Hello!! So here I am at my second attempt to build a solution to enable multi-modems and multi-bearers usage in OpenWRt, with re-connection handling for persistent connectivity.
This time I wrote a simpler application which only monitors existing bearers, and tries to keep them connected. An helper script is invoked whenever a bearer is added, connected, disconnected or removed. Was wondering for what could be the best path forward for reusing existing modemmanager protocol handler in this scenario. I plan to post the app to some git hosting site once it's in a more mature form. Thanks for the help and feedback! Enrico
