10.1.2 Response Format – BM70/71 Module to Host MCU

The BM70/71 module returns the following responses:
  • HCI event response – Number of completed packets event (opcode - 0x13) after successfully receiving a formatted HCI-ISDAP command. This also helps the host MCU to know about the acceptance and processing HCI-ISDAP command.
  • HCI ACL data packet – ISDAP command response (ISDAP opcode) with no additional values appended to the packet.

For more details on the general format, refer to Number of Completed Packets Event (Opcode – 0x13). The BM70/71 module returns an HCI-ISDAP packet with an embedded HCI-ISDAP lock/unlock command response to let the host MCU know the status of the operation (success or failure). This response does not include any additional data to the response packet. For more details on the format and values for the packet, refer to HCI-ISDAP Command Response (HCI-ISDAP Opcode – 0xXXXX).
