Over-the-Air Firmware Update Status
Frame Type: 0xA0
The Over-the-Air Firmware Update Status frame provides a status indication of a firmware update
transmission attempt. If a query command (0x01 0x51) is sent to a target with a 64-bit address of
0x0013A200 40522BAA through an updater with 64-bit address 0x0013A200403E0750 and 16-bit
address 0x0000, the following is the expected response.
If a query request returns a 0x15 (NACK) status, the target is likely waiting for a firmware update
image. If no messages are sent to it for about 75 seconds, the target will timeout and accept new
query messages.
If a query returns a 0x51 (QUERY) status, then the target's bootloader is not active and will not
respond to query messages.
