Enable the serial line monitor
Either if you are just configuring the module with your App, or designing a new µPanel for your micro-controller based system, it may be very useful to check the messages the module sends out on its serial line. The µPanel firmware allows you to easily monitor directly on your mobile device all the transmitted messages. To activate this monitor, open the App main menu and click on the Monitor Serial Line item, as follow:
A semi-transparent overlay will appear on the Panel window showing the last messages sent by the module on its serial interface
To disable the serial monitor, click again on the same menu entry. Please refer to the module command section for the full list of messages that can transit on the serial line.
