So I bought this bluetooth headset a pure beauty it self.
(Blackbeat903)
I have found out that my bluetooth signal is not strong at all.
The signal is supposed to reach 3 meters across. but as soon as I put it in my pocket, it begins to loose connection and I miss parts of calls/music.
I tryed to find out waht the problem is, first I thought it was because of programs in the background, that was not it, I even turn the mobile upwards in my pocket cause the transmitter is located in the upper part of the mobile.
But I geuss its just because the bluetooth is not strong enough to transmit trough human tissue? Now I can imagen that more poeple had this problem so is there a program of is there a way to boost my Bluetooth's signal range?
Greets.
It's just the way bluetooth is, you cannot simply change power class of bluetooth unit in HD2.
Well I didn't know about that.
But you can amplify allot of signals or sounds. So I thought it does not hurt to ask around.

Hi, as we'll all end up with an xda2, and they seem set to have built in Buetooth. I thought a thread all about the possitive applications for Bluetooth would be useful.
Can we steer away from the 'why can't it just have wifi' argument and actually discuss uses for bluetooth.
My thoughts are...
Bt gps mouse for the car would be fantastic. allowing you to pass the xda around the car and still have it picking up a signal. even take it outside the car when stopped to plan the rest of your route.
I have a broadband internet connection at home, running from a dedicated server machine, by Bt'ing the server i'll be able to wirelessly surf the net anywhere in my house, that would rock! internet based voice comms in my mobile. guess you could also Bt activesync if you really felt the need, but i tend to charge it at the same time so i'll stilll be plugging a cable in.
Bt headsets could be good. driving along the road and your phone rings etc...
Guess you could Bt contacts and appointments etc
Bt games could be interesting, think theres a worms clone called snails that already does this.
Does anyone know if it'll be able to connect to more than one Bt device at a time? say a gps system and a headset? or my server machine and a headset? Can anyone think of Bt uses that i've overlooked
i hope your house's not so big do not forget BTs range does not go over 10 meters and BT is much more subject to interferences frequencies with other devices than 802.b or g protocol. Even more BT max speed theorically is 2 Mbps, whereas wifi 802.11b is 10 and 802.11g is 54
i guess THAT makes the difference too
BT is more secure ok but within a very limited range and brandwidth, perfect for headsets
You can use multiple devices. BT effectively doesn't even give the full 10-meter specified range (unless it is Class II, 100 meter spec). It is very slow with an effective throughput around 700k. It is fantastic for headsets, and still much faster than GPRS. The GPS thing makes me laugh though...both devices need power, so why not just cable them together?!?
hey guys,
i have a little question,
i just bought a haicom gps receiver and use tomtom 2 software. When i get out of my garage, it takes always more than 15 minutes to get a signal. sometimes during driving i also lose it. How comes?
when i connect my device to the receiver and power, i get something like "connecting to t-mobile MMS"...
oh, btw i have a MDA II with latest NL t-mobile rom. 1.60....
if anyone could help please...
thanks!
The gps should only take this long when first used, after that it should lock in a matter of a couple of minutes, to test the gps properly it is best to test it outside the vehicle, I think most Haicom mouse gps come with magnetic base so stick it on the roof and drive around, if it works better it is probably becuase your car has a metallised windscreen which blocks the signal. The message about connecting to the service provider is an error due to the com port being accessed i think, mine used to bring up activesync every time but once I canged my activesync settings on the xda to manual instead of auto sync it solved the problem.
so i should always drive around with my window open?? and stick the receiver outside the car?
I would agree with Crusin Through - I think your car may well have some form of heated windscreen or heat reflecting windscreen. What car do you have.
If when you do place the receiver on the outside of the car you do get good signal you can get a special anntenna that had an outside part and an internal part that you can fit permanently to the car so you can still move the thing about. Bit like a mobile phone antenna.
Alternatively as you have the XDA II you can get a bluetooth receiver an place it on the rear parcel shelf (I think the wider heating strips won't affect it - but can't confirm it.)
John, I wasnt suggesting you drive around with your window open, I was suggesting a way to ascertain if your windscreen is the problem regarding your blocked gps signal, by the way I have used a gps on the roof and the window will shut almost all the way however as the last post mentioned you can obtain a re-radiating antenna, this will solve your problem if indeed the windscreen is the culprit.
Re-rediating antenna - that's the word I couldn't remember :lol:
ok guys, thanks. i'll try with such an extern antenna.
thanks for your help
Before you spend your money on the re-rad antenna - try the thing on the roof - if this works then the antenna is your only real option if you want to continue with the thing in the front windscreen.
I'd hate you to buy the re-rad and then find it doesn't work.
Incidently what car do you have? (Does it have a heat reflecting or headted windscreen)
And if it works outside,
you still don't have to buy an external antenna, as normally the windshield have an area where is not metal coating...
try to check the manual of your car..
i own a toyota Camry 2002 model, it has indeed a windscreen etc...
is it possible to get bluetooth relayed from my main computer all around my house so that i have wireless internet for my xda2?
something like a relayer of some description.
oh and is it possible to do this cheaply.. if not il go for wifi lol.
Yes
Yes, I use this all the time. I'd recommend getting a Bluetooth 100m adaptor. Connect via BT Activesync.
I would recommend wifi rather than bluetooth for networking in the house. It is much faster and far more stable and doesnt need line of sight.
i have a 100m connector for my pc. but my pda can only do 10m... so can i relay something in my room just to get the extra 10m or something? if so how?
bluetooth isn't line of sight either.
if you have the 100m repeater, it shouldn't matter how far the pda can see, the 100m repeater should get the signal into your room or wherever. only one of the devices needs to be strong, not both.
im not sure why its not working
the xda series bluetooth is only 10m
so as far as i know having a 100m bluetooth dongle dont help
because both ends have to be cetified for 100m for it to have a
range of 100m
maybe some repeater would work
of cause it would prob be more expensive then going wifi
also i find bluetooth slow

Bluetooth doesn't need line of sight either. Performance varies, but is actually better than WiFi in some circumstances. It does not matter that your device can only handle 10m, a 100m dongle will still transmit faster to a further distance, in my experience.
Well from experience and having spent quite a bit of money on setting up bluetooth networks in my home...it sucks bigtime. I now have wireless and have never had a problem.
Rudegear, yes you are correct, although it doesnt sound logical it makes no difference whether you have a 100 mtr adaptor on your desktop, if your phone does only 10 meters it will struggle. I had a 100 meter usb dongle but lost signal in the next bedromm.
The reason I mentioned line of sight is because the signal seems to be drastically reduced when it has travelled through a wall, whereas if it is in the same room it will be ok. WiFi is designed for fast data connection over distance while bluetooth is a low power application that has relatively low data speeds.
i think if i put a usb 100 m in a room upstairs aswell then itl work... i have a crappy comp tht i cud use but is it worth doing... i mean its another £20.. i probably will.. thx fr the help.
WIFI v Bluetooth
We have both running, and my wife and i both using simultaneously the XDAII, we measured manually the speed between, and WIFI was marginally better.
We were both in the room next door. However, we do get better distance from the WIFI rather than the bluetooth.
Both were centralised to the house, and both at the same height (about 1.6m high), and all can reach around the house. Few houses get over 20mx20m, so if you centralise either or, you can get around it easy enough with adequate coverage.
WIFI is generally better as most routers and WIFI units can handle multiple simultaneous access, where as bluetooth struggles.
would bluetooth not loose connection speed as the range inc much more then wifi would ?
the watt they send are much much lower
Hi Aidwe,
I just installed a Bluetooth Access Point DBT-900AP from D-Link (euro 50).
Bluetooth-to-LAN Access Point
Connect it somewhere to your internet router/modem/switch via Ethernet.
The box will get an IP-adress and via Bluetooth PAN-profile, you will have internet access throughout the house (circle of +- 10 mtr. around the access point).
My only problem: the Magician (T-Mobile MDA Compact) doesn't support the bluetooth protocol standard, but out of the box XDA's with the Bluetooth Manager will work.

Greetings Ben...
P.S. no info about the DBT-900 on www.dlink.com !
not sure about the bluetooth stack on universal but himalaya default ms bluetooth stack dont support PAN
Any PPC with 100 meters bluetooth?(or CF card)

Hi Everyone
After ive been suffering with poor bluetooth range (From my pocket to my ear bad) I found a random post on OP forums with a guy saying he fixed it by toggeling "Bluetooth Antenna Diversity" In developer options. So I tried this out, and damn now the range is just as my old phone.
But now my question is, does it come with any unknown downsides toggling that on?

Yes there is..
Normal Bluetooth usage involves emitting signal in all directions and then a direct line of sight is usually obtained and a direct link made between the source and target devices.
Diversity works by reflecting off anything it can in order to obtain the connection required.
Whilst this can work great Vs an unstable connection, it has a downside..
Input lag and response time mainly.
I've had this issue with a MacBook and the magic mouse 2 and magic keyboard 2 and trackpad 2 and several Bluetooth devices, in my front room from a distance of only 10 feet.
Problems involved disconnects, unwanted input and sporadic movement, also noticed it on a second device, Nvidia shield tv pro (the new £200 box)
So what was going on?
Well there's a soundbar in my room that uses Bluetooth, connected to my rear speakers, Alexa is also in the room and that is constantly transmitting.
Now unless the top android box and a £2k MacBook Pro with all the top accessories are all malfunctioning, there has to be a simple explanation.
It's the signals getting mixed up, blocking each other, interlinking and causing problems.
Sorry for the long explanation but that's my experience.
I can't even get this settings to stick I'm my dev settings I'm about to wipe my phone over this
Posting here as I think I used the wrong secrtion previously
I recently installed a Xtrons PQS90MTVL head unit in a skoda superb. I have a couple of questions on how to get it to work correctly when navigating.
1) It seems that you can set the navigation sounds to be a percentage of the radio volume but cannot set it to play at a given volume regardless. The problem is that the radio seems to be constantly on and there is no way to turn it off. The 'on/off' button simply mutes the radio - and the navigation sounds.
Often I am in an area where I cannot pick up a decent radio signal on the programme I want and just get static. In these situations I want to turn the radio off but still hear navigation sounds. I don't want to listen to loud static just so I can have the nav sounds play at a percentage of that static. Is there a way to turn the radio off but still get navigation sounds? (a workaround I have found is to play a media file instead of the radio and then pause playback. The nav sounds are then still a percentage of the - non existent - playback volume. However this should not be necessary)
2) It also seems that a Internet connection is needed for any navigation. even google maps won't do a search without it as it says I am offline. (is this true?)
I have bought the 4G wifi dongle but have a question about its use. Does the HU connect to the dongle, as far as data is concerned, via the USB socket that comes out of the back of the unit or is that socket simply powering the dongle and the HUI is actually connecting to it over wifi using the dongle as a hotspot? If so then I don't have to use the wired usb socket from the unit (which I suspect is underpowered) and can plug the dongle into an ordinary 2A USB socket that I have in the car, positioning the dongle near the roof for a better signal
Incidentally I did try using Android Auto with my phone using wired connection. That seems sort of OK but is not very reliable. Often when starting the car it hangs at the 'connected' screen, or even at the 'trying to connect' screen, although other times it seems OK
3) There is a small socket on the left hand side of the HU that looks like a slot for a small memory card or a sim card. It is labelled 'GPS'. What is that socket used for? it is not mentioned in the manual as far as I can see. - The manual is generally a bit hand waving though, excitedly telling you what you can do but not how to do it.
(I did try the xtrons forum but not only are the last posts there around January 2022 but there seems to be no way to register for it. Hence posting here)

First of all you need to fix your FM reception. You need to use a phantom power adapter to get some voltage to the OEM antenna.
There are some navigation apps which don´t need a internet connection. TomTom as example and others using offline maps. But you won´t get traffic messages if you don´t have an internet connection.
That would fix your white noise.
The FM radio can be closed if you use the back button on top right. If that does not help, chose the recent apps button on top and swipe the radio app away as for each other app... You really should learn how to use Android.
The navigation loudness can be set in the system settings. Depends on the unit where you can find it. In this case the navigation software needs to be registered as navigation in settings /Apps/Standard apps.
Regarding your 4G-WiFi dongle... The name itself shows the functionality.
It connects via 4G to the internet and provides the connection via WiFi to anyone in the car.... even too to the radio.
The GPS slot on your radio is nothing else as a micro-SD slot, which also can be used to store music on it or whatever else you want.
BTW: Seems that you are not that familiar with car electronics. May be a good idea to ask someone who can help you with some knowledge what has to be done.
Might be an easy task to just swap a radio, but there are more things behind than just swapping.
May I recommend 'Magic Earth' navigation, works fine with no internet but no live data of course.
At least there are a lot more offline navigation apps...

But without internet... no traffic data..

Thanks for a helpful reply. I have already fitted a power injector for the FM antenna which made some difference but I like to listen to radio 4 and there are parts of the country (along the M11, on the A5 in North Wales), where you cannot pick it up on any radio - and of course in Europe where I have just been for a few weeks where I usually don't want the radio on at all. That's why having the nav sound set as a percentage of the existing volume seems a bit odd as it implies you already have some other sound on. Better to have a dedicated channel for it or have the nav mute any other sound.
I'll look at doing all the swiping etc to turn off the radio by closing recent apps although this doesn't seen like a very safe thing to start doing when you drive into a area of poor reception. I was hoping the unit would have a simple press button like in the good old days!
The dongle info is also useful thank you. Xtrons do not make this clear at all. They imply that by plugging it into the socket on the unit you have made a (wired) data connection. If the HU is still only connecting over wifi anyway then I can install the dongle wherever I like in the car so that it gets a good 4G signal, instead of it having to be in the driver footwell at the end of the short USB cable xtrons supply and I can use a dedicated 2A usb adaptor to supply decent power .
I guessed the 'GPS' socket might have nothing to do with GPS. Shame Xtrons couldn't say what it was for instead of just mis-labelling it.
Incidentally. The SIM in the dongle would only ever be used for the navigation to receive traffic updates or bits of map or whatever it needs i.e I don't intend to be surfing the net or downloading Utube videos. Do you have any idea what sort of data requirements this would mean. Would a 250Mb a month sim be enough?
I'll experiment with your suggestions.

I'll look into those thank you. I use maps.me on my phone but couldn't get google maps to work on the HU as it said I was offline. Of course I still need an internet connection to download any of those apps and install them on the HU but I could just park near my house and using the house wifi.
Data plan for using navigation online data depends on the app you use and the amount of mileage per month.
You can use your smartphone first to see what you need in a "normal usage" month and then decide what you need.
If you use any offline map solution, it´s also some sort of usage dependency.
BTW... If you would invest into a higher data plan (2GB), you could use the app Radionator to use Online radio. BBC Radio4 should be in there too. Radionator is the best alternative if you want to listen to one specific radio station. Just needs a stable internet connection, nothing else... and the sound is mostly better than FM.
May be you can use the Navradio+ as alternativ solution for receiving FM radio. Depends on the MCU of your unit. Search for it in MTCD software forum.

I would recommend to use HERE WeGo, it served me very well for the years I didn't have mobile internet connection. Also it shows the max allowed speed in most countries, whereas Google Maps doesn't do that.
Sure, Here WeGo is a good choice, even without internet connection.
