@luffe LilyGO products...generally yes, they charge all the time while plugged in to USB.
You should conduct a simple test with your actual unit, as the documentation is very sparse.
(I could not find a schematic for your board)
Well, Arduino IDE 2.0 is much nicer to use with very little learning curve!
ESP 2.0.11 board defs are most likely mandatory but older ones may still work.
I would update all libraries and, then, I would copy the contents of the Lib directly to your libraries and overwrite all, as 'replace'. In that order.
["I typically download the zip from Git Hub and launch from the extracted files. Is that good enough? If I have that local file structure do I need any of the libraries installed? "] should be OK.
Also, thanks again for your feedback on the video. I've just updated it on Youtube (it will take up to 80 minutes for the High Quality versions to be available) but even what's there now is much better. Here's the link: https://youtu.be/YdbTDYZ2Ues
@oragion : Hi Guillaume, did you succeed finally? What do you think of the Lilygo card? I am currently thinking of using the SIM7600 version, with the same operator as you, but I've not purchased the Lilygo board yet.
