Transparent mode behavior for outgoing TCP and TLS connections

For Transparent mode, the IP (IP Protocol) setting specifies the protocol and the DL (Destination Address) and DE (Destination port) settings specify the destination address used for outgoing data (UDP) and outgoing connections (TCP and TLS).

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

To initiate an outgoing TCP or TLS connection to a remote host, send data to the XBee 3 Cellular LTE-M/NB-IoT's serial port. If CI (Protocol/Connection Indication) reports a value of 0, then the connection was successfully established, otherwise the value of CI indicates why the connection attempt failed. Any data received over the connection is sent out the XBee 3 Cellular LTE-M/NB-IoT's serial port.

A connection is closed when:

• The remote end closes the connection.
• No data has been sent or received for longer than the socket timeout set by TM (IP Client Connection Timeout).
• You make and apply a change to the IP, DL, or DE.
