TL (TLS Protocol Version)

This command applies to the XBee 3 Cellular LTE-M/NB-IoT.

Sets the TLS protocol version used for the TLS socket. If you change the TL value, it does not affect any currently open sockets. The value only applies to subsequently opened sockets.

Note Due to known vulnerabilities in prior protocol versions, we strongly recommend that you use the latest TLS version whenever possible.

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