Example
In the following example, the destination device reports that a unicast data transmission was
successful with a 16-bit address of 0x7D84. The transmission could have been sent with the 16-bit
XBee/XBee-PRO® S2C ZigBee® RF Module
0x8B
Identifies the serial interface data frame being reported. If Frame ID = 0 in
the associated request frame, no response frame is delivered.
The 16-bit Network Address where the packet was delivered (if
successful). If not successful, this address is 0xFFFD (destination address
unknown).
The number of application transmission retries that occur.
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
0x00 = No Discovery Overhead
0x01 = Address Discovery
0x02 = Route Discovery
0x03 = Address and Route
