Hi all,

I'm writing an application to capture the button events of the Bluetooth
headset for WM5.0 smartphone, but I don't know the keycode of them, and
there is no WM_KEYDOWN, WM_HOTKEY events triggered when the buttons pressed.

What can I do?

Thanks,
Qiang He

I have absolutely no experience with bluetooth headsets, but just thinking
logically, I would be surprised if bluetooth headset sends WM messages at
all.. it's a radio signal, that acts probably like a serial port, or at
least stream of data. And over this connection, data is exchanged. I'd
assume those buttons are part of a standardized protocol for head sets.
On the PocketPC side, this could be converted into WM messages, but there's
no point.. WM is for message loops, not for data packets exchanged over BT.

Compare it to a USB scanner that has scan button.. those buttons don't
generate WM_KEYDOWN either.
