Hello. I am working with another ESP32 project. It will be used as a ultra low power tracking device. It will have GPS and GSM.
The device will be used in a different region than I am at hence I am concerned about remote firmware update. At some point in the future, I may need to release an update and flash all the required devices. There may not be wifi available.
Can someone share their knowledge or suggest me any ideas what are other options to perform a remote firmware update for the device? Is it possible to do over GPS?
