Hello all,
I am working in a project that I need GSM connection and to be battery powered, therefore the arduino MKR 1400 was a good solution.
Everything was working fine until yesterday, when I start working with my prototype I noticed that It was not working and the CHRG led was constantly blinking. It's not even being recognized by the computer. I checked the voltage levels and it's normal. I think that i am suspicious about the bootloader, but it is a big guess and I didn't found any good documentation on how to reflash it with the MKR board.
I'm hoping on revive the board somehow, since in my country those are very expensive.
Any help is appreciable,
Gardin.
