Hard-configuring a BT Module
Hi,
we are building a custom board using the TI AM335x ARM processor and want to base it on the armhf port of debian linux.
to save cost/power/etc), our system will not have a usb bridge, so the usual method of adding a bluetooth device via plugging it into a usb port will not be used.
is it possible to configure bluez and/or the kernel to recognize and use a BT module (an LSR TiWi-uB2) that has its HCI serial interface hard-wired to a specific serial port / uart on the ARM?
also, is the LSR TiWi-uB2 known to operate with bluez correctly?
thanks for any help you can suggest.

you are looking for hciattach or btattach tool to attach a serial port to the kernel.

No idea. Nobody ever send me board and enough instructions to test this all. There is TI support in hciattach. So at least there is a starting point if it does not work out of the box.

Aha! Excellent! Thank you, Marcel.
