The following command upgrades modem firmware over the serial port exposed by the nRF93M1 module:
nrfutil 93-series modem-firmware-upgrade --firmware <firmware_path> --serial-port <serial_port>
For example:
nrfutil 93-series modem-firmware-upgrade --firmware mfw_nrf93m1_update_from_1.4.1_to_1.5.0.bin --serial-port COM9
The command performs the following operations in this order:
- Clears flash storage.
- Uploads firmware.
- Verifies firmware.
- Waits for the modem firmware upgrade to be applied (unless
--skip-wait-for-applyis set).
Use 93-series version-query before and after the upgrade to confirm the installed firmware version.
