Hello,
I use sim cards from different ISP, therefore I have to flash devices each time I want to change ISP in order to change APN.
Would it be possible to dynamically change APN, that way I could swap sims from different ISP without changing anything.
Sincerely,
If you have some means of feeding the new credentials to your device, you can store them in EEPROM and on next boot pull the new settings from there.
For the Electron/E Series, this technique can be used:
A similar method can be used for the Boron, but the code would need to be slightly different.
