Firmware over-the-air upgrades

A firmware OTA upgrade upgrades either just the application firmware or both the application firmware and the bootloader firmware on a device. OTA firmware upgrades must be to a different version, re-installing the same version as what is already installed is not supported.

Note Performing an OTA upgrade will erase any file system or bundled MicroPython code on the target device, even if the OTA upgrade does not complete.
