11.4 Command Status Event (Opcode – 0x0F)
The BM70/71 module sends the event response to indicate receiving the command described by the command opcode parameter and that the BM70/71 module is performing the task associated with this command. Some of the HCI commands or HCI ACL data packets (in this case HCI-ISDAP commands) take time to complete, this event response makes it possible to prevent the host MCU from waiting for the command to finish. If the command cannot begin to execute, the status event parameter contains a relevant error code and no command complete event follows. In case of programming, the host MCU uses this event response to get the status on the HCI-ISDAP commands, which takes time to complete. For more details about the format and information returned to the host MCU, see the following tables.
