Bluetooth pairs but won't connect

I have successfully paired my nexus 7 to my evo 3d and my HP laptop. However, it will not connect to either one. There is no connect option visible either. Both the laptop and my evo 3d connect fine to each other and other Bluetooth devices. Is my nexus 7 faulty or am I missing something?
Edit: ok it connects fine to my Bluetooth headphones, so why won't it connect to my phone or my laptop?

i used foxfi and pdanet to pair my nexus 7 to my sgs3 and tether my nexus 7!, maybe those 2 apps could help

Thank you. That does seem to allow me to tether. But why won't my tablet connect on its own though the Bluetooth setting?

is anyone else having trouble connecting (not pairing) their nexus 7 to a laptop or a phone without using any external apps? Just native settings.

Not sure if this helps, but I have Verizon and it seems that they block Bluetooth tethering while on 4G LTE. I could get my phone and nexus 7 to pair, but wouldn't connect. However when I switches my phone to 3G, my tablet and phone connected no problem. Its nice BC when they are connected your tablet automatically uses your phones internet. If I just want to use 3G, I go this route. When I want to connect them while my phone is on 4G LTE, I have to use foxfi/pdanet.
In other words connecting while the phone is on 4G seems to be blocked. Switch to 3G and see if that doesn't work to connect.
Hope this helps.

I tether 4G with my stock RAZR maxx without a problem. Turn off WiFi on both devices and it will probably work perfectly.

I've paired my Samsung Galaxy S2 with my Nexus 7 and I can't access my phone from the tablet using ES File Explorer, though I can access the tablet from the phone.

Clicking on the other device in bluetooth settings usually gets it to connect for me. If I walk away from my tablet with my phone I have to redo the process.

This doesn't work for me. The only option I am given is to unpair. I have tried it without WiFi as well. No go.

I have the same issue as you. It may be that our phone don't have the right BT Profile for "Internet Access".
Are there any other options? I've tried FoxFi and that didn't create the "Internet Access" profile either. I'm on a Samsung Stratosphere with 2.3.

I have also been trying to tether my new Nexus 7 with my old Xperia X10 mini. I can pair but not connect. I can't access my Bluetooth settings on my Nexus. I can't pass files vie Bump either. I can't get the wifi tether to the phone working either: My phone doesn't allow me to download Foxfi, my phone says PDAnet doesn't work on my version of Android. I bought the Nexus in the UK but I'm using it in Germany. My phone is with O2 which typically requires an additional €20 charge to tether. Any advice would be appreciated.

I think you folks are missing a setting?
Hi
Aside from pairing, on the device whose connection is being shared (i.e the phone), you need to goto settings-->More-->Tethering And Portable Hotspot, and make sure that 'bluetooth tethering' is selected.
This works on my Galaxy Note. 4.04 ICS
No 3rd party apps are required to do this. Note that Bluetooth PAN only came to android in 3.0. If your phone runs 2.3x or below, you'll need the software discussed elsewhere in this thread to make BT tethering work.
Whatever internet connection the phone has is shared, whether wifi or 3g
NB: Its a bit flakey! OK once connected, but requires BT to be cycled off/on on both ends...

Mine also "pairs" but won't connect to my Galaxy S3. Also can't get Wifi direct to work between the two (ICS on the S3)

Theres a wee bug in android where after a new pair, restart, or occasionally on bluetooth disconnections bluetooth tethering will become disabled on the host device.
Go to the device with the Internet Connection and (on ICS / JB) hit Settings -> More -> Tethering & portable hotspot -> Bluetooth tething and check it.
You'll have to redo this regularly but combined with an occasional bluetooth off/on unpair / repair this will work.
(Nexus 7 / Galaxy Nexus - both rooted stock)

Hi
If you don't have the screen below (or equiv) mentioned in my previous post, then you wont be able to tether without using 3rd party apps. I guess the BT PAN profile is missing where this option is not available.

Thanks for this. All was working fine between my UK (stock European with a few Vodafone apps) Samsung Galaxy S3 (SIII) and Note 10.1 until I upgraded to 4.1.1 on my S3. It seems this option was added then or disabled by default. All working splendidly now, cheers.

Droid Razr Nexus 7 connection
All,
You can tether the 4G LTE on a nexus 7 you just have to enable bluetooth tetheriing in Setting > Tethering & Mobile Hotspot > Bluetooth tethering
Without doing this, it won't link via bluetooth tethering.As for laptop, you have to allow access point in your laptop in order to allow the Nexus 7 to fully connect to your laptop to share files.
Cheers!

This thread has the most similar problems that I have. By me the problem is opposite. I need to get internet connection on my phone (xperia U) and the only way is through tethering through my iphones hotspot. Bluetooth says paired but not connected and wifi hotspot isn't found in the list of wifi networks.
Bluetooth tethering worked fine on ICS but I downgraded to GB and now nothing. I can't install 3rd party apps yet because no internet on phone.
Is there no other option? Is it either GB, lag free phone but no tethering option or laggy ICS phone with tethering??

What's the best way to share my phone's Internet connection with my tablet?

It would be nice to just be able to carry my phone in my bag, so that when my tablet is within range of WiFi it uses that, but cal use my phone's 3G connection if wifi isn't available.
What's the best way to achieve this? A wireless hotspot from the phone? Or Bluetooth?

Wifi tether is best way to go. I would suggest foxfi because you can have a wifi password if necessary. Also a free app from the play
store, just be sure to watch your data limit!

Try install BlueVPN(ics client) from Google Play. Activate and pair your device with 3G phone. Launch BlueVPN, Selecet your 3G phone and BlueVPN will do the rest. Good luck

Pair your phone and your tablet. And you are connected.

Disable lockscreen security when connected to AW, BT, or WIFI device. ROOT REQUIRED

OK, so I have to use my fingerprint to unlock my phone. For me this gets annoying when I am in my car or extremely busy working and my screen times out. this wouldn't be so much of a problem if the note 4 had lollipop but we dont at the moment.
I solved this using the following:
Root
Xposed
and a module called NO LOCK HOME
You can set it to any bluetooth or wi-fi connection, or to a specific one. I set mine to my car but changed it to any bluetooth because of my moto 360 and hands free are the only other devices that connect over bluetooth. Plus if you go out of range it auto locks or when the the screen is off depending on your settings.
you can download NO LOCK HOME straight from xposed installer

You can do this via Tasker as well.

[Q] Phone hotspot, mobile hotspot device or 3G USB modem?

I looked through this forum trying to find which method gives the most stable Internet connection for these head units but I'm not having any luck. Which connection have you found to be most stable: the phone's hotspot, dedicated mobile hotspot device or a 3G USB modem?

I don't think a lot of people have tried all 3 options to give an objective opinion. I've only tried connecting to my phone's hotspot and my home router and it works fine on both, however it sometimes takes a while to connect. I would even select the SSID manually and hit "Connect" and it wouldn't do anything. Then I just leave it alone and it connects all by itself in a few minutes.
I haven't used a USB modem so I can't say anything about that.

Any hiccups or gotchas when using your phone as a hotspot? Does the phone get hot? Does it drain the phone battery even though plugged into the charger? What's the longest you've had the phone running as a hotspot at a given time?

I haven't had any problems with this really. The phone doesn't get any hotter than it usually does (I have a Galaxy S6 Edge). The battery still charges while hotspotting when it's plugged in to my car charger. I've used it for a couple of hours at a time with no problems. The only issue you MAY find is the battery drain even while plugged in, bt that will really depend on your phone and your charger so that's a "try and see" situation.

I tested it out today for hours (using phone as hotspot) and you're right - it's a stable experience, no connection issues. The phone didn't get hot and it basically still charged. I was presumed a mobile hotspot device would yield the best experience versus a 3G USB modem (because I saw too many posts citing connectivity issues across multiple models) and phone as a hotspot (because I feared it'll get hot and be subject to connectivity issues too), but phone as a hotspot is solid enough (and I save $20/month over the other two options).
Thanks for the input!

I've tried all 3 options and i've settled on 3G USB modem with Phone hotspot as backup.
in my radio it NEEDS to be a huawei modem or the radio wont recognize it (tried with a TP-Link but couldnt even see it).
The advantage over both phone hotspot and dedicated hotspot (and the reason i use this solution) is that it turns on with the radio, and no need to worry about unsecure network as it isnt shared.
The disadvantage is that it is a bit slow on startup, and looses connection from time to time (could be network related tho)

Yeah, that's why I was weary of going with the 3G USB modem option as most say theirs lose connection often.
The phone as a hotspot option is still working very well for me. My only complaint is that I have to manually turn it on every time I get in the car

Not the one i used... I needed to turn it on when i needed it (usually just before i started my car). The one i used had a power saving mode so if it wasnt used for 15 min it would turn off to save power on the internal battery (7h capacity)

Surely there must be a way to disable that and have it power on automatically when connected to AC. I understand tehe power saving feature, but it should be possible to disable it at least when it's not using it's own battery.
In my case, I use my phone to share the connection via wifi and I set it up to automatically start the hotspot when it's connected to the radio via bluetooth and turn it off when it disconnects. That way I don't even have to worry about turning it on/off.

I thought about setting it up that way too, but my phone doesn't automatically reconnect to the heat units Bluetooth when in range/in the car. How do you get your phone to auto reconnect to Bluetooth and how do you set it up so that hotspot auto starts after that connection?
Sent from my LG-D850 using Tapatalk

It's actually the headunit that automatically reconnects. Go to the bluetooth options and check the settings for your device (after you've paired it). By default it should automaticqally reconnect though, unless you changed it, but check anyways. As for the automatic hotspot, I use an app called NFC Retag. It's meant to be for automating tasks when you use an NFC tag (hence the name, duh!) but it also supports some other trigger, such as detecting when the phone connects to a specific device via bluetooth. I'm using it since I already had it for a few things I do with NFC tags and it's worked like a charm, but I guess you could also do the same with Tasker or some other app.

Just another follow up - phone as hotspot is still very solid for me. The only problem is it cuts out temporarily at start of calls but cuts back in seconds later in a call.
Hope that helps someone

I have Tasker setup on my phone to automatically activate/deactivate the wifi hotspot when it connects/disconnects bluetooth to the headunit. The headunit then automatically connects when it detects the wifi signal. Works great and I never have to touch anything or take my phone out of my pocket.

Ya, I got it to auto connect by checking the button in the Bluetooth app. The thing that sucks is phone screen needs to be awake and unlocked for hotspot to turn on. Otherwise it just sits in the background saying "Authenticating..." forever and never turning on

Automate Hotspot

Hi All,
I am trying to automate enabling hotspot when connected to my car's bluetooth. I tried with both Tasker and Automate applications and from what I can tell, it cannot be done without root access. I have not seen a successful root for the S8 yet (could be overlooking) but is there any way to actually achieve what I am looking for?

Never heard of automated Bluetooth - hotspot setup before
Sent from my VS987 using Tapatalk

Not with BT per say, but I used to achieve auto hotspots in my car on my OP3 with a little NFC tag.
Was stuck on my car holder. Worked a treat.

It can be done. In fact, I did it for my car. So yes, tasker is a way to go. So in tasker you do:
Trigger: State->BT connected->Name CAR KIT.
Then single Task WiFi Tether ON.
No root is needed to do that and it works.

I use 'Hot Spot Starter' Creates the wifi hotspot all the time automatically when connected to the car via Bluetooth

This works for you guys w/ the S8??

This does not work on my S8 (T-Mobile). It says it is turing on the hotspot and will actually turn of my WiFi, but the hotspot does not turn on.
I also tried HotSpot Starter and I get the same results. It turns off my WiFi, but does not turn the HotSpot on.
Anyone have a confirmed way of doing this on an S8?

This does not work w/ the S8. There is another plugin which works. The dev of tasker is no help for us S8 people saying it is our carrier which it clearly is not since it doesn't work on sprint either.
https://forum.xda-developers.com/android/apps-games/app-toggle-wi-fi-hotspot-5-0-xda-t2981805

just use bixby ... create a quick command with all u have to toggle.
i use the word "start Driving" to turn on mobile hotspot and turn off wifi , then turn on bluetooth.
"finish drive" does the reverse

the native tasker hotspot toggle doesn't work for most of us w/ s8s
dave

Probably the trick is to install a SM-G950U1 firmware instead of native carrier's SM-G950U firmware. I got my U1 firmware over here https://forum.xda-developers.com/tmobile-galaxy-s8/how-to/eng-boot-root-t3608353

Here is solution for you, it works on galaxy s8, note8 and android 8.0 oreo
https://play.google.com/store/apps/details?id=com.carspot.wifi

Was struggling with this issue for a while, tasker tricks didn't help and autoinput looked not very reliable/convenient.
Solution I found -
1. just install GoodLock from Galaxy Store: http://apps.samsung.com/appquery/appDetail.as?appId=com.samsung.android.goodlock
2. In the application main menu Enable/Install "Routines" component
3. Configure your routine - select bluetooth connection in Condition and "Turn Hotspot On" in action section.
As the app was developed by Samsung, it has access to enable hotspot by default. Works on my galaxy S8+ with latest android Pie update.

Whoops, wrong thread! Sorry
