This program will start when a TCP connection is established. For this example, we are going to use Netcat. The command bellow should connect the host with the device. When the connection is opened, the device will start to stream data from the internal temperature sensor with ASCII characters. Binary data can also be sent.
$ netcat 192.168.7.1 7777
