enable bluetooth handsfree profile in WEC7

Other Parts Discussed in Thread: DM3730, WL1271

Hello,

I would like to know how to enable bluetooth handsfree profile in WEC7.

I have added these two lines in platform.reg:

[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\HandsfreeProfileOn]
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\hci]

The board I'm working with is Mistral EVM with DM3730 processor and WL1217 module. Running WinCE6 OS, the bluetooth device works fine. The other bluetooth device can discover EVM and find the services like "File Transfer, Object Push, Serial Port, Personal Area Network User, and Audio Stereo".

However when WEC7 OS is running, the services provided by EVM are "File Transfer, Object Push, Serial Port, and Personal Area Network User" without Audio Stereo. I'm just wondering how to enable the Audio Stereo service in WEC7.

Thanks,

James

I also tried to use btagconfig app to turn audio on. I got an error message "Operation failed: 21". The error number 21 means the device is not ready.

What could be the reason?

Thanks,

James

What driver for the WL1271 did you use for WEC7? Where did you get it from?

Also remember if you include the Bluetooth Profile Managment API component (SYSGEN_BTH_BTHUTIL) it will add registry settings that leave the radio off by default and the driver will not load.

I got driver for CE6 from Adeneo. Our company has an agreement with Adeneo. I only ported bluetooth driver from CE6 to CE7. Bluetooth works on both OS. The only difference is that there is no "Audio Stereo" service in CE7.

David,

Thanks for the help.

I can activate Bluetooth radio by running "btcmd -radio visible" and it can be discovered by other bluetooth devices. My problem is that I cannot enable the "Audio Stereo" service of the bluetooth on my board in CE7.

Thanks,

James
