Bluetooth uses the protocol stack API to read device MAC addresses

Recently in the porting QQ IoT protocol, you need to read the device MAC address.

Read the CC2541 device MAC address method, there is a direct read Mac register, you can also call the protocol stack API. This takes the form of a call API.

The core content is Api:gaprole_getparameter

This API can refer to the 102th page of CC2541 Software Developer's Guide, where you can find the definition of this function in the IAR itself, and gaprole_bd_addr is a type that represents the MAC address of the Bluetooth device.
