This is "nn::bluetooth::IBluetoothDriver".
This is "nn::bluetooth::IBluetoothDriver".
The bluetooth driver implements the bluetooth protocol over h4/uart.
It interfaces with the [[Bus_services#uart|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.


Support for "nn::bluetooth::*" was added to sdknso with 6.x.

The bluetooth driver implements the bluetooth protocol over h4/uart. It interfaces with the [[Bus_services#uart|uart]] service to actually talk with the bluetooth hardware.
The bluetooth stack is Broadcom/Cypress brcm BSA (for example, see [https://github.com/hardkernel/buildroot_linux_amlogic_brcm-bsa here]).


The following L2CAP services are registered (dynamic channels): SDP, ATT (GATT), RFCOMM, HID (PSMs: 0x11, 0x13, 0x8001, 0x8003).
