Receive Packet
Frame Type: (0x90)
When the module receives an RF packet, it is sent out the UART using this message type.
Example. In the above example, a device with a 64-bit address of 0x0013A200 40522BAA sends
a unicast data transmission to a remote device with payload “RxData”. If AO=0 on the receiving
device, it would send the above frame out its UART.
Frame Fields Offset Example Description
Start Delimiter 0 0x7E
Length
MSB 1 0x00
Number of bytes between the length
and the checksum
LSB 2 0x12
Frame-specific
Data
Frame Type 3 0x90
Frame ID 4 0x00
Identifies the UART data frame for
the host to correlate with a
subsequent ACK (acknowledgement).
If set to 0, no response is sent.
