The RAK5010 is a cellular board based on Quectel's BG95 modem (Qualcomm chipset). A Nordic nRF52840 microcontroller "runs the show", connecting to the modem via UART. This is a nice combination for a number of applications like remote sensing, application tracking, and Bluetooth <> Cellular gateway. Let's walk through the process of developing for this board in the Zephyr RTOS.
Golioth works with Qualcomm. The Golioth Firmware SDK, release 0.12.0, supports the Zephyr Modem subsystem. This enables support for more modem technologies, starting with Qualcomm, and support for the Quectel BG95 as a first class cellular modem.
