RAK3401 RUI3 support

Is the RAK3401 + RAK13302 supported by RUI3? I would like to flash the RUI3 firmware to my RAK 1 Watt Starter Kit so I can use the AT commands. Is this possible?

I flashed rui3_rak4631_latest.zip to my RAK3401 and unsurprisingly, it doesn’t appear to work. I cannot connect to it over serial and issue AT commands.

The release notes say it’s supported (RUI3 v4.2.4 Firmware Update: RAK3172 Flash API & Fixes), but I cannot find a download for it.

Welcome to the forum @beala

The RAK3401 is supported by RUI3 as a nRF52 module with Bluetooth only.
There is no support for the LoRaWAN transceiver available.

‘rui3_rak4631_latest.zip’ cannot work, as it expects a LoRa transceiver on the module, but the RAK3401 does not have this transceiver. LoRa is only available with the RAK13300/RAK13302, but they are not supported by RUI3.
