Using BBBW as Bluetooth SPP device

Hello!

I’m using BBB for a few years now and they are great and I’m fan of these!
With BBB, I used to add a external Bluetooth module and to interact with it through a serial port. A mobile application connects to the BBB (the BBB is the salve and waits for connection).
With BBBW, I hope to be able to remove the external BT module to use the onboard one. I made quite a lot of googling around this but I’ve not been able to find out how to setup a slave SPP mode using the BBBW’ bluetooth.

Could someone help me on this topic?
Thank you very much!
Florian
