Receive (RX) Packet: IPv4 - 0xB0

Description

The XBee 3 Cellular LTE-M/NB-IoT uses this frame when it receives RF data on a network socket that is created by a TX request frame or configuring C0 (Source Port).

Note For NB-IoT, TCP support is dependent on the network. Contact your network provider for details.
