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.

Frame-specific Data
0x06 - ACK
0x15 - NACK
Bootloader Message
Type
0x40 - No Mac ACK
0x51 - Query (received if the bootloader is not active on
the target)
0x52 - Query Response
Block number used in the update request. Set to 0 if not
applicable.

20 0x00
21 0x40
22 0x52
23 0x2B
24 0xAA
25 0x66
64-bit Address of remote device that is being updated
(target).
64-bit Target Address
Checksum
0xFF - the 8 bit sum of bytes from offset 3 to this byte.
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.
