The bluetooth driver implements the bluetooth protocol over h4/uart.

It interfaces with the [[uart]] service to actually talk with the bluetooth hardware.

The code seems to be derived from a broadcom stack. A good starting point for similar source code can be found in the MICO project: https://github.com/yinhongxing/mico/tree/ea67ff3659f12d730d4dc3b8d547b093bd2ee2ee/MICO/bluetooth_bte Note that the library files contain many (symbolized) functions which match btdrv.
