BLE Chip SDK(single point)

What is the DP point CCR8 used for the door opening method during the development of door locks?

The specific algorithm of CRC8 is: CRC8=CRC16 (hardware type, member id, frozen state) & 0xFF. For the specific algorithm of CRC16, please refer to the source code in the door lock SDK: uint16_t crc16_compute(uint8_t * p_data, uint16_t size, uint16_t * p_crc).

Bluetooth door lock SDK integration, how to modify the uuid, arch_key and mac in the firmware program?

Key is the auth-key in the program, UUID is device_ID, h_id can be ignored
