6.4. Monitoring Real Time Sensor Data Using the Telnet Interface
The temperature and light sensor data can be monitored using the command line Telnet interface. The Telnet
interface is very similar to UART, except bytes are sent over a TCP connection instead of an RS-232 cable.
Figure 13 shows a screenshot of the Telnet connection to the CP2201EB. Pressing the S key starts printing and
updating samples on the screen. Pressing the P key pauses the updates. A key difference between this method of
accessing sensor data and the web browser is that the MCU initiates updates of the information on the screen. In a
web browser, the browser must request data from the MCU. Note: The Telnet demo has been configured with a
fast update rate. We recommend closing the Telnet connection when finished viewing data to free system
resources for other parts of the demo.
