modem AT commands tests #networking

Rafael Dias

I'm starting to work with the modem SIM7000.
To do this, I'm using a B-L475E-IOT01A with the DF Robots SIM7000 arduino expansion shield.
Well, I'd like to exercise the AT commands before integrate it into the device driver. Are there some mechanism to enable the terminal on the IoT node board, enable the serial port between the iot node board and the SIM7000 expansion shield, control the GPIOs to turn on/off  and verify the modem status and etc?

Is this done only programmatically?

best regards and thank in advance

I think the best starting point would be the modem shell, I believe there is a sample in Zephyr.
