Jasjam Bluetooth issues

[plains203]

Bluetooth switches off on our imate jasjam's we have at least 10 of them with this issue. When paired with a car kit they may receive a call through the kit then the next call through the device and when they check the device they find Bluetooth has turned off. To get it to re-enable they need to soft reset the device 3 times out of 5.
They are using 2 different brands of car kits.

After researching my bluetooth issues I found the 3518_09 fix for the imates bluetooth issues.
I have installed this patch on 6 or more imates and had mixed results. All of them were the latest official telstra jasjam rom. Some devices now have better connections to car kits with no bluetooth connection issues and a couple of them are now worse. The bluetooth radio switches off and then won't turn back on. If you reset the device then bluetooth will work again. Basically with or without this patch Bluetooth will switch off randomly on the imates. Some devices behaved better after the install and some worse. Frustrating.

Is anybody else having this issue?
Does Radio 1.41 help bluetooth issues at all?

Thanks

Radio 1.41 will not fix my bluetooth issues. I have read that much in the wiki :)

However it seems to be a problem either when I switch off the ignition with the phone in the car kit or remove / replace the phone on the car kit.

I didnt seem to have noticed an issue in the past month or so but since then its getting to be quite a pain. I have to go back into the comms manager and re-enable it most of the time.

I have an M3100
Operator Version 14.123.1.614
Rom Version 1.23.61.4
Rom Date 07/13/06
Radio Version 1.16.00.00
Protocol version 32.53.7018.01H

Since running the latest Orange Updater file:
SPV_M3100_ROMUpdate_0407.exe from Orange website.

www.orange.co.uk/business/downloads/SPV_M3100_ROMUpdate_0407.exe

This updated the firmware to:
Operator Version 14.211.1.611
Rom Version 2.11.61.1
Rom Date 03/23/07
Radio Version 1.38.00.01
Protocol version 32.71.7020.12H

This seems to have fixed my bluetooth issues. Also the phone is running much faster.

thanks for the info. is it possible just to take the bluetooth drivers from one rom and use them in another? I see that the 3518_09.cab has a bluetooth driver in it (i assume that's what it is) so maybe that is one of the files to look for. any help?

I have extracted the files from the rom posted above. I am going to try replacing btagext.dll, bthuart.dll & serial_btur.dll.
