I am sorry to report that i getting nowhere. I have looked at the links but I am missing the basic fundamental understanding.
I have loaded the firmware from the Mashtastic site (success) but I never see any code, never need to open an IDE (Platorfmio or arduino) so how can I edit a .h file?
Is there a firmware file on Meshtastic I should be looking for.
Is it simpler to abandon Meshtastic and code for Lora and IO sensors. That just leaves me with a range issue that the Mesh solves.
I hope my stupidity will help future stupid people.
Thanks
