A sample app to debug and validate cellular modems on balena devices

Cellular Test App for balena

This is a simple test application to validate if a cellular modem is working correctly with a balena device.

With this app one should be able to validate the stability of the modem on balena without the application container causing adverse side affects.

The app includes the the mmcli binary to interact with the modems via dbus.

The src folder found in /usr/src/app in the container also include a python script to run a speedtest on the device to .

ERROR: HTTP Error 403: Forbidden

Hi,

I'm using this python file in my app to retrieve the network speed from the device in the background services. But while I'm testing this script today, it is giving me the error saying forbidden.

I'm pasting the exact error message below for a better understanding.

Retrieving speedtest.net configuration...
Cannot retrieve speed test configuration

Error start.sh script: invalid path or index string specified

After start i get the error:

What is going wrong?
I think my celluar modem (Huawei E303) is not available. How can i check if the cellular modem is available?
