Secure Sockets Layer (SSL) certificate checking
Currently, the XBee Cellular Modem is not capable of checking the certificate of the remote end of the
socket connection. We will add this support in the future.
This means that the device cannot authenticate the remote end of the connection. Although the
connection is encrypted, there is no way to verify that the remote server is the expected server.
Socket timeouts
The XBee Cellular Modem implicitly opens the socket any time there is data to be sent, and closes it
according to the timeout settings. The
TM (TCP Client Connection Timeout)
command controls the
timeout settings.
