I have to setup Quectel EC25-E hooked up to my Rasp Pi Zero. I can setup the ppp connection but manually.
This is what I do: Quectel module ppp connection
However, I have to make this pi headless and so no SSH or manual input possible. I am looking at creating a service which executes a script on boot but that would do it once but I want some sort of error handling which would try to connect in case of network issues such as dropouts.
What would be the best way to pull this off?
