Location based reminders (Shopping List?)

Have you ever told yourself "The next time I'm at the shops, I better pick up XYZ", but then you get the shops and completely forget about it? It could be any variant, like:
"The next time I'm at the bank..."
"The next time I go to Mom's place..."
Etc.
Imagine having a GPS powered application that popped up a reminder the next time you were within X metres of a pre-saved location. That would kill the battery, wouldn't it, because you'd have to leave the GPS on the whole time.
I like what Google Maps have done to their latest edition which can show you an estimate of your location based on Cell Info. Can this be used to make a location based reminder application?
Perfection would be if the application could pickup the location of an Outlook Task as well, and if it recognises a saved location in the text of the Task, it would pop up. Just a thought...more likely wishful thinking
I've search the net, but I don't think an application with this capability exists. If anyone knows of one, please do let me know. If someone thinks they can make one, that would be great too. I'm not a programmer, but I would willing be a tester or provide creative/functionality input, if you like.
Thanks,
K

Please be encouraged
This is a great idea...and if we dont do it here we will wish we had....one of those things that just makes life simpler and once we implement it wont know how we got by without it....let's say you have something in the trunk or back seat that you keep meaning to drop off...say the dry cleaning or the computer you promised your neice or church....but you never remember obviously till you get home and see it while grabbing your things out of the car...well this type of service would go a long way to help you look like you're not the absent minded geek that we all know we really are!!.......while we're dreaming it up...how about a part of it functions like this...lets say you're driving out and about and see say a house you like...cause maybe you're in the market... a few taps would bookmark your location within a few hundred meters....and the next time or every time depending on how you have it set up...you'd be alerted that you were near your bookmarked location...sweet

Well apps like SKScheMA and PhoneAlarm allow system changes based on cellid so it should certainly be possible to set up a pop up box with a todo based on cell id. I guess the tricky part would be a nice gui.

you'll need to have gps on all the time, so your ppc won't last half a day !

You obviously didn't read the entire post. I already mentioned the battery drain issue if the GPS was used. The alternative was CellID. Thanks for taking an interest though.

That's a great idea. Phonealarm has location based profiles using cell ID. I'm sure that a skilled developer could use that to make an app that does what you offer...

TrackMe offers this feature

sorry I replied too fast
now another problem is, from what I've seen on my device, tri-positionning was not accurate at all, around 500m accuracy as opposed to few meters of GPS. That could still be useful from town to town needs, though (like "go see your mother !" )

I followed the link to the App you suggested. Although the main page for the app doesn't talk about this CellID feature and the reminders, it looks like the update logs have them mentioned, and the screenshots look like the reminders must work the way I'd like.
UNFORTUNATELY, I've got an HTC TyTN which doesn't have a lot of memory for me to install .NET Compact 3.5 (I've got other required apps installed which I can't remove) so I can test the darn thing.
Perhaps if some of the other contributors to this thread would like to try it out and let me know, please?
I'm going to buy a Touch Pro next month (when they finally release an Invisible Shield for it) and I'm going to officially love this program, it it does what I want it to.

Don't worry about it. We all skim through sometimes. In fact, when I first mentioned the idea to my brother, he barged in with the same comment, just as I was getting to it
I think 300 - 500M would be sufficient if you needed to remind yourself to pickup a tub of your favorite coffee then ext time you were at your supermarket (unless you live next door to the supermarket).

For those of us that live in relatively big cities, 500m is usually enough for those things...

I took another look at the app you suggested (Is it the one by Espinosa?). It looks like it's a full featured location tracking application, but I don't think it has the specific feature discussed in this thread.
In fact, the app seems to be way too big to be practical for everyday use anyway.
If I'm looking at the wrong TrackMe, do let me know.

Funny this came up because I was checking google android last night and noticed that someone won 250,000 with an app that does exactly this as well as lets you price check other stores in the area

In TrackMe -> yes the one by Espinoza -> Menu|Tools|Geofence|ShowAlerts|Add|General
where you have the option of specifying a Latitude and Longitude the distance from the lat and long, and whether to fire an event based on if you are in the area or not. In the NotificationsTab you can specify if an e-mail or sms is to be sent, and what address/number to send the notification too.

I don't want a SMS or an e-mail. I want that the application will open a specific note when I reach a certain place. Or a pop-up reminder.

PhoneAlarm would be the best. It does not have the exact feature you are looking for, but you can ask it to run certain program/application when you are within a certain CellID choosen by you. You can also label the CellID to your liking.
If you buy the software, you can actually ask the author to add the feature you want. He is very open to suggestions. And if you do, you can also ask him to monitor the CellID first, and if you are in the CellID, then the GPS can be used to track the range of the specified point.
Good luck.
Edit: I just checked the software, it has the feature of using the GPS for location detection.

PhoneAlarm can indeed solve the problem. You need to make permanent notes for each location, and then tell PhoneAlarm to open the specific note for your location.
For example: you make a shopping list note, create a profile on PhoneAlarm that's called Shopping, and tell it to open that note when switching to Shopping profile. You can keep the note itself, just change it's content. The same thing can be done for the bank, parents' house, etc...
My only problem with PhoneAlarm is major battery drain...

[Q] Augmented Reality App Development

I would like to know how the AR app Layar/junaio works. I want to build a similar app but for indoor guide of a particular building. The building is fixed and the plan inside the building doesn't change.
The crux of the app would be to guide visitors of the building to their destinations.
End Result: Possibly throw a map as output or provide wikitude like drive.
Typical Usage:
Visitor visits the building, scans the QR code posted at the entrance and downloads the app from appstore/market
At the lobby, user opens the downloaded app and scans another huge picture (Can be barcode or any unique picture)
The app shows the different areas of the building just like layar or junaio and then user selects a particular area and requires a navigation map as output from the point.
Will be using different unique pictures/barcodes at different point to locate the users location instead of relying on gps as it would not help indoors for navigation.
Any inputs on how to start would be of great help. I'm an experienced mobile app developer and have developed regular utility apps, api mashups etc. But nothing in AR.

AR apps usually use a combination of GPS, Compass, Altitude, Accelerometer, and gyroscope data to figure out the exact location of a device. They then access the camera view and place graphics on top of it.
The problem with your idea is that most AR apps usually come in one of two forms:
- Outside without pinpoint accuracy to position, (the device knows exactly the heading so the direction is perfect but the distance may be a litte off)
- Based off a target symbol (think 3ds card, barcode, etc) to keep a point of reference in the scene
Unfortunately your application would require you to be indoors so it would be extremely hard to figure out the exact position because of the GPS loss. At best you could have a series of "scanable qrcodes" to then display a map and direct the user to the next point. You could determine the exact position of a user by calculating the change in gyroscope data from the beginning to the current time, but that would hard especially dealing with inaccuracies and interruptions.
I think the safest bet for your app would be to have codes at certain points to help at your users. If anyone else has a better answer please correct me XD

That would be epic... but not all phones have gyros. Soo...
What about having devices setup to emit a distinct directional non audible noise that the phone will listen for and use that to key the user to what room they are in. All phones have a microphone.
Or key off music in a room if there is any

Well, I have already discounted the use of gps. Series of QR/Scannable Codes
should help me solve the problem. Since I would only be showing a map from the QR/Scannable Code point.
Let me give you an example of how I would like to implement in real life.
User enters walmart, opens the app after scanning the first scannable code, he gets to see the different areas/offers on the camera view (AR)
and then would like to give a map output on how to reach within, when the user selects say "groceries" on the camera view. The app should give a map output on how to reach the groceries area from the scanned location.
I believe lot of people get lost in locating things in a large retail store. Walmart was just an example to explain, there are other stores which have this issue.
Guys, your inputs on the idea itself are welcome.

I dont think it will work in a noisy environment like malls, retail stores etc. But works well in a ambient place like museum. Though ur idea is brilliant, dont know how it will work in reality.

Yes that sounds like it should be possible. An honestly what you could do is have a large "maker" (some sort of distinguishable shape and color or pattern) on a cube in the middle of the store, that way when the user holds up his phone to look at it, the phone will know what he is looking at depending on which face on the cube it is. you can then use that as a reference in the view and map out location icons over the view.

[IDEA] Improving GPS accuracy

Our Developers are making great work, now we even have dedicated TEAM
But sadly revision after revision we all getting them more and more faster, stable...
But can we do something about GPS ?
I was forced to install GB because of badly accuracy with CM10 GPS. I know you can change NTP server or use other stuffs. But could we have official GUIDE for making GPS on JB better? Its sad because after installing GB alot of apps dont work because they need android 4.0+
Ultimate guide for getting our GPS better.
When im using bus and have hand to hand GB and JB on both i9001, GB have no problem with getting Fix when JB can't get one.
Using Maps JB look like im flying above the city, and GB is tracking me fine with little errors.
Ever played Ingress with that kind of GPS ?

I had the same problem, but in my opinion noone can fix it, because of on JB we using GB libs, which are not fully compatible

There is a post were someone used some specific gps.config file and his/hers GPS is working better then before. If i only could find the post

Code:

Using Brood GPS tool dedicated to GB I got a gps.conf file looking like this
(its for Europe > Poland)
Will try that on CM10 mayby that will help, a bit. Any more teaks/tips ?

no such file in stock, and you need this cert to use SUPL_TLS_HOST
SUPL - Secure User Plane Location
- In reference to SUPL_HOST and SUPL_TLS_HOST
The values can either be in FQDN (www .blahblahblah.com) or a direct IP address. They are both ways of retrieving AGPS data, and while both methods are secure to prevent anyone tracking you** the difference lies in the source. SUPL_HOST can be any open server such as Google's or any network your phone can register to, SUPL_TLS requires a security certificate to connect to the site (hence, SUPL_Transport Layer Security). The downside to the SUPL_HOST is that the requests can get flooded or can go down, and with SUPL_TLS the certificates can expire (think expired security certs for webpages). All current information I can find says that only ONE of each SUPL location service is supported by Android.
Furthermore, in the field for SUPL_TLS_CERT you can't just arbitrarily input the value "SuplRootCert." There has to actually be a cert already there for the conf file to call upon. Some SUPL_TLS connections have multiple certificates such as seen in the MyTouch 4G (no slide).

INTERMEDIATE_POS=1

INTERMEDIATE_POS - Intermediate position
Values are 1 for on, 0 for off
This will give a jumpoff location for giving a rough estimate of your location based off cell tower registration. For instance, let's say you live in Dallas and you're driving to Austin. You turn on your GPS mid trip, and the last time you had it on was back home. By default the Dallas location will be loaded, and if this is turned on when you first fire up Maps you should see the map rapidly zoom to an approximate location. This switch is used in conjunction with ACCURACY_THRES.
unrelated to speed or accuracy
ACCURACY_THRES=2500

Click to collapse
ACCURACY_THRES - Accuracy threshold
Values are numerical, 0 disables the switch
This value is measured in meters(need confirm?), and for the intermediate location you want a pretty large net. The intermediate position gets you a quick and dirty estimate of where you're at while the AGPS/Satellite location data is syncing, and pulls information off what towers you're registered to. A value of 5000 gives you a larger net than 3000, and while 5000 is less accurate the 3000 value will take longer to get you a position.

Maybe someone here would like to try out my Faster*** like app on the play store called TopNTP. The app is developed by me in cooperation with RC @crypted. He maintains an excellent NTP server. All parameters of the gps.conf can be modified. If someone comes up with the most efficient gps.conf for the SGS1 I can update the app with a profile for this device (my first android ever, SGS1 rocks!)
An expert on this matter, @FadeFx once told me to lower ACCURACY_THRES to 500, might be a tip for thos who try.

You, sir, are ignorant. You rehash discussions over two years old. And, instead of reviewing those many discussions I openly had, you decided to defame me.
Thank you for showing why XDA is becoming worthless to DEV communities.
NTP.ORG has a lot of cable modems and other overloaded and poorly networked time servers. I use Stratum II time servers (look it up). Further, I calculated NETWORK HOPS AND LATENCY from many locations to mobile data connection points. Learn that a little bit and you'll be much better off.
If I'm sitting in Caen, France and my carrier (Orange) has its outpoint for my mobile data traffic as London, England, then using a server near me is nonsense. Further, NTP does not rely on your physical location or timezone. It's absolute time for the almanac data.
XTRA data is a funny one. Let us assume I just copy data. Do a MTR monitoring from about 20 global locations and write a script to pull xtra data to those same 20 locations. See the great latency that occurs through the reliance on the original servers. Then, do the same for mine. You will see a huge decrease in latency and procurement time across almost every mobile carrier I was able to get tests ran on.
Now I don't feel like going on to much more to try to educate someone who refuses to read my previous long postings on these subjects...
But hey, I'm an asshole as you indicated. I did nothing of use. Sadly, over 10 million query's a day say differently.

i am not into the mood tp discus that with you. best latency is something your server IS NOT providing for me so i see no point in using it.

I didn't want to get involved in any discussion and I won't.
Leaves me to say, try the app and use the ntp server, use the app and use one of the xx other servers out there or don't use the app at all.
Some report great results, others don't report anything. We hardly get any negative results reported.
The service is offered for free and remember, if you don't like it eventually, the app backs up your old configuration and is able to restore it also.
I'm always open for suggestions to improve the app or the database. I would love to include an entry special for the gt-i9000 as this device has brought me into android app development.

ExtensibilityApp class in WP 8.1 Silverlight

Hi all,
If you've read the text that USED to exist here before, scratch that. Big Thanks to @Sunius1 for clarifying what I thought was a win. Due to this, I DID find something interesting in regards to the ExtensibilityApp class (Windows.Phone.System.LockscreenExtensibility.ExtensibilityApp). I happened to also find a hidden capability "ID_CAP_SHELL_DEVICE_LOCK_UI_API" (Seems to be a locked CAP because it only works on Emulator. I get a deployment error on my if I try including this capability). I suspected that these two worked together, but I wanted to make sure of this.
Before we get started, read through the documentation from this site: http://msdn.microsoft.com/en-us/lib...lockscreenextensibility.extensibilityapp.aspx.
We have the following methods:
BeginUnlock
EndUnlock
GetLockPinpadHeight
IsLockScreenApplicationRegistered
IsSystemOverlayApplicationRegistered
RaiseToastNotifications
RegisterLockScreenApplication
RegisterSystemOverlayApplication
UnregisterLockScreenApplication
UnregisterSystemOverlayApplication
EDIT: After the release of the Live Lock Screen app, my speculations about the ID_SHELL_CAP_DEVICE_UI_API capability and the ExtensibilityApp object were correct. Thanks to @jessenic for finding out a good bit of info on this with me.
It seems that in order to get this working, we have to add an Extension to the WMAppManifest.xml
<Extension ExtensionName="LockScreen_Application" ConsumerID="XXXXX" TaskID="_default" ExtraFile="Extensions\\LockAppExtension.xml" />
In the LockAppExtension.xml:
<?xml version="1.0"?>
<x:Extension xmlns:x="urn:LockApp">
<AppID>AppNameForLockScreen</AppID>
</x:Extension>
As usual, Microsoft doesn't really give us much in terms of documentation.. Probably because it isn't meant to be used by the normal developer Confirmed: For now we have to actually ask for permission in order to use the cap. As to whether we'll get that granted? Who knows....
All of these methods have no parameters at all, but I can almost guarantee this has to do with having an application that can control the lock screen.
This thread will be for efforts in breaking this open and seeing whether we can create lockscreen applications..

Lockscreen App by @-W_O_L_F-

There are actually two Windows.winmd files in Windows Phone SDK, one for Silverlight 8.1 apps and one for Jupiter 8.1 phone apps (located in C:\Program Files (x86)\Windows Phone Silverlight Kits\8.1\ and C:\Program Files (x86)\Windows Phone Kits\8.1\). There's only one the phone. And some APIs support only one app type (it's phone limitation it seems: faking .winmd file results in Platform::InvalidOperationException, saying you cannot use that API from this app type). That explains why the one on the phone has more APIs available than either of for single app type.
As for LockscreenExtensibility - it's documented, just not available for Jupiter apps:

Well that is very good to know! Thanks for the clarification. The best part is that I was actually able to compile without receiving an error (somehow).

I found something that may be of use in order to get the LockscreenExtensibility working (I just tried on a Silverlight 8.1 app and got access denied).
<Capability Name= "ID_CAP_SHELL_DEVICE_LOCK_UI_API"/> <----. Can't be used OOTB
EDIT: I just tested this in the Emulator and it really IS the capability that the LockscreenExtensibility needs in order for it to work.

<Capability Name= "ID_CAP_SHELL_DEVICE_LOCK_UI_API"/> <----. Can't be used OOTB
EDIT: I just tested this in the Emulator and it really IS the capability that the LockscreenExtensibility needs in order for it to work.

I assume this is the thing Rudy Hyun used to create the lockscreen app at Build?

I speculate that this is what he's using. I bet there's more going on that we have yet to figure out. It also could be that the base class EXISTS, but the full implementation isn't available yet. Who knows.

Ah, Yes that makes sense. I wonder if there are any other "half-baked" API's in the SDK?
Edit: I Know it sounds stupid but honestly I think we should have a thread dedicated to finding odd API's (Just found one: Windows.Phone.System.SystemProtection, nothing terribly useful though)

there are also some hidden APIs in the current SDK for 3D Touch-enabled Apps!
From WP Central:
Some of the features include APIs for gestures, side interactions and even heat maps.
Crazy stuff.
Believe it or not, some of these APIs for developers are in the current SDK, they're just not visible. What this mean though is developers will have access to this 3D Touch technology for their apps. It also means that Microsoft will have a small batch of third-party apps supporting this 3D Touch technology on launch day.

Yea, even though those 3D touch APIs may be available, they're not particularly useful, as they require special hardware to work.

That is true. Sort of of a side question though, has anyone made a OEM account and looked over the API documentation there? There maybe some useful things we could learn about WP and maybe further a jailbreak for all WP devices....

API isn't much useful as long as you cant really use most of functions due to policies.

Sounds like there will be a dev preview update to enable lockscreen functionality quite soon. Joe also mentioned keeping the lock screen in memory. So 512 MB devices won't get the functionality soon....

Good stuff. Another question: can apps show the action center? Because I want code an app to show notifications on lockscreen. Thanks

something to force the volume/music control on the lock screen to automatically open would be really useful as well

Updated first post with some more data since the Live Lockscreen App debuted yesterday. There's more I didn't get into, but I want others to dig in and find out

I suppose we can only speculate how it works at this point, but if I had to guess, it goes like this:
1. You have 2 projects in your LockScreenApp solution, one for the application to register the lockscreen, and the second one for the actual lock screen application.
2. The former would use ExtensibilityApp APIs to register the the second one, coupled with the manifests so it's all "valid".
3. The second application is just a another app that is able to process input and draw whatever it wants on the screen. That would explain why there's a delay at it starting when you press lock screen button while the phone is sleeping (probably it's a time for .NET to startup? Direct3D app should be able to start much faster).
Although this is only speculation, I think this makes sense, because that's how background tasks work on Windows, at least. I wonder though, why Microsoft is not releasing the APIs to be used in public - are they afraid somebody will make a lockscreen application that will drain the battery fast or something?

I don't think its that but most likely the fact that the API is un-optimized, some of the facts you stated (i.e. Slow start up, documentation is lacking) etc... The fact the OS needs to be updated to show a section telling the user what lock screen app has taken over (since the setting page doesn't now)
Edit: Remember what Joe said about keeping the lockscreen in memory and 512MB devices might not be supported for that reason? Yeah seems like they aren't doing that since you can see the resume time for the lo screen is wayyy to much

You are correct. Two projects: One is the settings page, which is the main entrypoint of the app when it's opened from the start menu and the second one is the actual lockscreen app.
The settings page uses the ExtensibilityApp APIs to register the second one as a lock screen application. That second application is another 8.1 Silverlight app that uses a LockScreen_Bridge WinRT component that has native access to read what is shown on the lockscreen from the WP Settings item.
It then uses some storyboards to make it do different things as you're swiping up and down on the LayoutRoot grid. It does use a timer so that's where that little lag comes from.
The only background stuff it's doing is latching on to system events ("Start button being touched for example").
I can see where MS would be protective of this. They DID say that they would be releasing a public version of the API at some point. I'm hoping it's not one of the situations that leaves it public only when they've approved you to be able to use it.
It does suck that it's restricted to 8.1 Silverlight though. I could see some Music Apps wanting to take advantage of the lockscreen like this.

Quite interesting...!
The API in itself is quite powerful, custom lockscreens with weather animations are possible! http://wmpoweruser.com/wp8-1-live-l...amazing-lock-screen-weather-animations-video/

Xiaomi Mi Bluetooth LE Band Protocol reverse engineered!

Since there is no Forum for the Mi Band ...
After receiving my Mi Band yesterday I started digging inside the sourcecode of the Mi Band App to find out interesting stuff.
It works with all BLE device, not only Xiaomi ones
It uses an unsecure protocoll which can be reverse engineered, so you could build an API out of it or port it to other mobile OS.
I will update algorithms & the protocol asap, but there is already a lot of usefull stuff on the protocol inside my blog: http://allmydroids.blogspot.de/2014/12/xiaomi-mi-band-ble-protocol-reverse.html
If someone is interested in writing an API, contact me.

Great! But some questions:
1) when you say "I started digging inside the sourcecode" you mean the smali decompiled from the app apk, right? Or is there some open code I missed?
2) if we create an apk which exposes the API (for example via android intents) can it connect to the device at the same time with the original Mi app? Or is the pairing exclusive to an app so we have to hack the app itself (for example via an Xposed module)? (Note: I'm extremely ignorant about bluetooth LE).
Thank you!

Decompiled and looked at smali + java from smali (which skips stuff so make sure to check original smali, too)

We are currently developing a BLE app to a customer and I agree that it is horrible. Android has really messed up everything they could when it comes to BLE.
Other apps could access at the same time. Pairing is done through the Android not the app itself. Although it could be that the band itself limits this somehow. I will check that soon.

Awesome...I'm glad I found this. I just got my band and didn't realize it only worked with the app from XIAOMI. Very disappointed. Also, I can't even set mine up right now. I set up an account and when I go to sign in it says I have the wrong password! When I go to reset the password it has to SMS me a verification code and it NEVER COMES. Total waste.
I hope you guys get this working soon and we can use it with apps that won't send our data back to mainland China. Do you know if this will work with 'Sleep as Android'? That's what I got this for. I thought it was a basic bluetooth device, not some proprietary POS.

I uploaded a very first Android App today but it can do only very few things yet - but currently it doesn't do the setup. I don't know that app so I don't know if it can interact with other devices and if, how good. But the Miband can detect sleep phases (pretty good for me) and can wake you, so I guess it could be possible.

Ah you tried the .apk from /bin? Thats not working. You have to compile it. I will upload a working one when it has some more features.

Hello again,
downloaded and installed Android Studio. Compiled your project, all went quite smooth. Unfortunatly the app still does not quite work. Without the band close it quickly complains that there is no band around (good). With my miband close, it scans for ever (not good). Somehow it does not communicate with it.
The BLE Device Monitor detects it well.
Regards

Hi,
I tried the same actions. Seems problem with discovering.
According to google:
startLeScan: Added in API level 18 This method was deprecated in API level 21.
Changed API from default 21 to 18 - nothing has changed.
MI device is visible in other BLE apps, in Bluetooth settings as well. Original translated app working well.
Nexus 4, android 4.4.4
Android Studio 1.0.1
Regards,
Klym

yeah, I commented out the code that actually loads data. Will fix that.

Could you get the Mi Band to sync with Google Fit?

There is an api for Sleep as Android.
https://sites.google.com/site/sleepasandroid/doc/sleepcloud-api

How about accelerometer raw data or sleep data, is it available?

Hi,
i try to connect my miBand with my laptop.
I found this site with some source code:
https://bitbucket.org/OscarAcena/mibanda
I installed all dependencies and run this as sudo python miband.py:
Code:
from gattlib import DiscoveryService
service = DiscoveryService("hci0")
devices = service.discover(2)
for address, name in devices.items():
print("name: {}, address: {}".format(name, address))
But after 10 seconds, I get an empty result.
My hciconfig shows this:
Code:
[email protected]:~$ hciconfig
hci0: Type: BR/EDR Bus: USB
BD Address: 00:C2:C6:59:91:73 ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING PSCAN ISCAN
RX bytes:1475 acl:0 sco:0 events:71 errors:0
TX bytes:1723 acl:0 sco:0 commands:47 errors:0
Does anyone know, what to do?

I'd happily swing a few bucks for an app where it can link with google fit.

Well...

I just have a quick questions about the possible functionality of the MiBand and what has been discovered thus far. Can the LEDs be individually controlled? Also, I know you can dismiss an alarm by touching the MiBand, does it detect this touch through motion or is there a capacitive switch in the MiBand?
I don't know how much help I can be, but I'm just curious about the technologies that they've been able to pack into the band.

Seems there is no "touchpad", when needed (alarm and pairing) bracelet just detect vibrations from finger knocks.
Very likely it's internal firmware function and can't be accessed outside.
Also some advertising: useful additions for Mi Band

@motioncoding
Can you please tell me what Bluetooth profiles are supported by Mi Band ?
For this:
1. Go to the Bluetooth settings on your phone
2. There you will see the names of Bluetooth devices listed including the Mi Band
3. There will be a gear (or options) icon beside the name... tap on that and please post a screenshot of the screen that appears.
Thank You
