XBee® Wi-Fi RF Modules

RX (Receive) Packet: IPv4
Frame Type: 0xB0
This frame is used by XBee when RF data is received using the Serial Data service on the
port defined by the C0 command.
Example: When a module in API mode receives an IPv4 transmission, it will produce an
RX notification (0xB0) and send it out the UART or SPI. This example is the response to a
UDP transmission to IP address 192.168.0.103 with data ‘Hello’ from the source address
192.168.0.104.
