TX (Transmit) Status
RX (Receive) Packet: 64-bit Address
RX (Receive) Packet: 16-bit Address
API Identifier Value: 0x89
When a TX Request is completed, the module sends a TX Status message. This message will indi-
cate if the packet was transmitted successfully or if there was a failure.

NOTES:
API Identifier Value: 0x80
When the module receives an RF packet, it is sent out the UART using this message type.

• “STATUS = 1” occurs when all retries are expired and no ACK is received.
• If transmitter broadcasts (destination address = 0x000000000000FFFF), only
• “STATUS = 3” occurs when Coordinator times out of an indirect transmission.

Received Signal Strength Indicator -
Hexadecimal equivalent of (-dBm) value.
(For example: If RX signal strength = -40
dBm, “0x28” (40 decimal) is returned)
