u-blox / Mbed OS example-C030-out-of-box-demo

Example program demonstrate the use of the User LEDs and the User Button. The example also initializes the I2C3 Bus for the battery charger BQ24295, sets the battery charger and the cellular module driver, powers up the cellular module. However, the UART2 , which is used for communicating with the module, is not configured. Hence, the Serial USB Sniffer could be used for exercising AT commands from a development PC.
