ZigBee Transmit Status
Frame Type: 0x8B
When a TX Request is completed, the module sends a TX Status message. This message will indicate if the
packet was transmitted successfully or if there was a failure.
Example: Suppose a unicast data transmission was sent to a destination device with a 16-bit
address of 0x7D84. (The transmission could have been sent with the 16-bit address set to 0x7D84
or 0xFFFE.)

Start Delimiter 00x7E
Length MSB 1 0x00
Number of bytes between the length and the checksum
Frame-specific Data
LSB 2 0x07
Frame Type 30x8B
Frame ID 40x01
Identifies the UART data frame being reported. Note: If
Frame ID = 0 in AT Command Mode, no AT Command
Response will be given.
16-bit address of
destination
5 0x7D 16-bit Network Address the
packet was delivered to (if
success). If not success, this
address matches the
Destination Network Address
that was provided in the
Transmit Request Frame.
60x84
Transmit Retry Count 70x00
The number of application
transmission retries that
took place.
Delivery Status 80x00
0x00 = Success
0x01 = MAC ACK Failure
0x02 = CCA Failure
0x15 = Invalid destination
endpoint
0x21 = Network ACK Failure
0x22 = Not Joined to Network
0x23 = Self-addressed
0x24 = Address Not Found
0x25 = Route Not Found
0x26 = Broadcast source failed to hear a neighbor relay
the message
0x2B = Invalid binding table index
0x2C = Resource error lack of free buffers, timers, etc.
0x2D = Attempted broadcast with APS transmission
0x2E = Attempted unicast with APS transmission, but
EE=0
0x32 = Resource error lack of free buffers, timers, etc.
0x74 = Data payload too large
0x75 = Indirect message unrequested
Discovery Status 90x01
0x00 = No Discovery
Overhead
0x01 = Address Discovery
0x02 = Route Discovery
0x03 = Address and Route
0x40 = Extended Timeout
Discovery
Checksum 10 0x71 0xFF - the 8 bit sum of bytes from offset 3 to this byte.
