Hello,
OK, this is driving me crazy. Everytime my Samsung Vibrant connects to my car stereo via bluetooth, it will download the phonebook. The reason is drives me nuts is it takes over the display of the car stereo saying "Downloading". It may take 15-40 minutes to complete.
I don't want it to download it at all! I will use the phone to dial anything.
Below are links to the phone, car stereo and bluetooth adaptor unit to help anyone solve this problem. Kenwood couldn't help.
The manual for the head unit, on page 24 simply says "
To cancel downloading of the phone book data. operate
the cell-phone"
Operating the cell phone in any way didn't appear to stop the downloading of the phonebook
It appears the profiles involved are:
OPP is a profile used to transfer data such as a phone book between units
PBAP (Phone book Access Profile)
Turning off Data Sync on the Vibrant didn't affect downloading.
In the Bt-300 bluetooth adaptor manual, I have what is designated a Model J headunit.
Please can somebody help with this, as this is hundreds of dollars of equipment that I can't use for it's intended purpose. Do I need to unlock/jailbreak the phone?

Maybe they should have put a wifi radio in with the dongle too to alleviate the wifi problems while streaming bluetooth as well. I ran this same scenario a hand full of times and at best I lost 10mbps at worst I lost 13mbps I'm also within 5ft of my router. Its still comletely fucntional for any streaming media I've used so far as long as I'm at home sitting on my router.
In the first test in the video the music was coming from the internal speaker in the prime the download was 13.21mbps and the upload was 14.00mbps. the second test I turned on bluetooth and it connected to my external speaker download was 3.30mbps and upload was 6.32mbps. For both tests ping was unaffected over all the tests I did the ping was between 54ms and 31ms.

I can't tether the internet from my cell phone to my prime when I'm on 3g and listen to music or stream video with my bluetooth headset on it wont even load. I don't even try anymore and this is a huge issue for me. I wish we could have gotten a solution in the gps dongle that also worked in the dock and wasn't so hideous
My new evo lte randomly connects and then drops bluetooth connection in my vehicle. (My OG EVO paired with it once and then ran perfectly every time i entered the vehicle) Anyone with similar problem? Suggestions?
My Audio would automatically dim after a while. As in the volume would go really low until I hit pause and play again. Was listening to an audio book and it would do this like every 40 minutes it seemed. Other than that it was connected to my car bluetooth for hours without dropping the connection. Like 6 hrs
I'm having the same problem connecting to my Pioneer car stereo. It connects fine at first, then randomly drops off, or won't re-connect without rebooting phone.
I think its HTC Car dock app. Because when I use the app CarHome ultra it works perfectly. That sucks because I actually like HTC Car dock, but I guess 3rd party apps for me.
I'm looking for a solution to stream audio to multiple smart-phones without lag.
Can this be done?
Using a laptop (win/mac) as a broadcasting station with WiFi connected.
Is there a limit to the connected clients in a Wifi Router?
Can LAG be minimised?
FM transmission is not a direct option, because it's illegal to do. Although most smart-phones have a FM radio and this option produces no LAG.
This is a project to supply listeners to a small open air concert with the direct audio feed, without the use of central amplifiers.
Hi all,
first post, this issue starts to drive me mad :crying:
My device is a Lenovo C2 (K10a40), not rooted (If BTW anyone knows how to root this device: You're welcome )
I have Bluetooth connections to many devices. My car and my wife's car (Phone Audio and Media Audio) , Raspberry pi (Media Audio, to stream from device to rasppi), a Philips TV with a "built in" Bluetooth speaker, to stream from device to TV, and my Linux PC (Phone Audio and Media Audio), to dial etc. from my pc when sitting at my desk.
ALL of these connections are working fine, except one, to one car:
- When paired for the first time, all worked fine for a long while, days/weeks/months
- No idea why, once and suddenly when re-connecting the device and the car, after some seconds, AOSP standard media app "Music" starts, and again after some seconds, a popup says "Bluetooth Share has been terminated" (or very similar, translated from German msg).
- Car says on radio screen "A2DP has been terminated"
- Both car and device tries infinite to reconnect, same issue
Tried the usual stuff:
- Clearing cache: no change
- Resetting network (and Bluetooth) settings: no change (after painfully adding all WLAN and Bluetooth connections again :crying
- Rebooting both car's radio and android device. no change
I didn't try and really, really, really don't want to try a factory reset, would take me ages to reinstall and reconfigure everything, as I'm not sure if simply restoring a backup after resetting the device will re-introduce the error anyway. I don't want to test it :silly:
What sometimes, whyever only sometimes helps (for a short while, sometimes days) is to drop phone from car's paired devices and vice versa, and re-pair after that.
My question is, could be a deep technical answer if necessary: What on earth triggers the start of the "Music" app, after (re-)connecting both device and car? The Bluetooth crash *** ONLY *** happens, if "Music" app starts. Before first crash "Music" app has NEVER been started. Now, when successfully paired after dropping connections as described, "Music" app does also not start at first. But as soon as "Music" app was used to stream media to car, it's going to start automatically after reconnect. Although if for instance media playback has been terminated before disconnecting, e.g. for listening to radio. For a while then reconnect with automatic start of "Music" app works, and after a while the crashes appear again.
On the other hand, if "Music" app is started automatically after a re-pairing, after dropping connections before, at the first Bluetooth connect, the crash is ALWAYS a result.
I also found out, that if I'm DISABLE A2DP "Media Audio" profile in the connection settings of the android device, connection is stable and "Phone Audio", including adressbooks sychning etc. works fine and stable. But unfortunately not "enough", I need A2DP for navigation audio.
Any hints how to get rid of these "Music" autostarts would be great!
