Do I need to build the OOB Demo to evaluate the Pinnacle100?

You do not need to build the OOB Demo on your own, if you have need to upgrade your OOB Demo version on your Pinnacle 100 modem or MG100 gateway, please use our official releases found here: https://github.com/LairdCP/Pinnacle-100-Firmware/releases.

Found at this link are several firmware file types depending on how you plan to upgrade, *.hex is for SWD while *.bin is used for BLE, UART, and HTTP over LTE. Additionally, 480-00052 is for the Pinnacle 100 and 480-00070 is for the MG100.

See the Firmware Updates section for how to upgrade over the different interfaces, BLE/UART/HTTP over LTE

To upgrade over SWD, use the JLINK USB port on the Pinnacle 100 DVK board, for the MG100 see the MG100 Hardware Guide section 5.4.4 to learn how to connect a J-Link debugger to the board for the upgrade using nRF Connect or Nordic Command Line Tools.
