TCP Server Example
The device can also act as a server and wait for incoming connections. In this example, a listening socket is
opened. When a connection is established from a client, the module receives an unsolicited response. When the
client sends data, another unsolicited response is received. The application switches the module to on-line data
mode to read the received data. The client closes the connection and the module receives another unsolicited
response.
