Asset Description
480-00052 firmware is for Pinnacle 100 DVK.
480-00070 is for MG100.
- *_LTE-M.hex = AWS OOB demo firmware only (MCUboot image not included). Flash this image to the device to leave MCUboot unchanged. You can use this image to update a device that already has the MCUboot boot loader installed, v3.x (GA3) or newer.
- *_LTE-M_FOTA.bin = AWS OOB firmware binary used for firmware-over-the-air updates.
- *_LTE-M_full_image.hex = Complete AWS OOB firmware image including MCUboot boot loader. This is the binary used in manufacturing to flash a blank Pinnacle 100 modem. Use this if updating a device that has firmware 2.x (GA2) or earlier.
- *_NB-IoT* files = same as above, but are the LwM2M demo over NB-IoT.
- *_CT* files = same as above, but contact tracing firmware using LTE-M and AWS cloud connectivity.
Updating to This Release
If coming from 2.x firmware, flashing the full image via SWD is required.
nrfjprog -f NRF52 --program 480-00070-R4.1.0.1618931859_LTE-M_full_image.hex --chiperase --reset
If coming from 3.x firmware, BLE, UART, or SWD can be used to update.
