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.
