The RAK10700 is coming with a pre-flashed firmware.
It is not based on RUI3.
What do you get when you send AT+VER=? over USB to the device?
The device is not connecting to a “Gateway” it is connecting to a “LoRaWAN server”. A gateway is just receiving LoRa packets and forwarding it to a LoRaWAN server.
I didn’t explain myself correctly, I always use chirpstack V4
In your experience, it would be better to continue with RUI2 on this device or update and load new firmware, checking the components are the same as those I use for RUI3
I was thinking of using rui3, is it possible to update RAK4630, since I can do other functions and the example firmware that you keep GPS is very similar to the one that comes with RAK10700
I am not sure what you mean with RUI2. There is no RUI2, there is an old discontinued RUI V2, which is for our old WisDuo modules RAK811, RAK4200, RAK4270. RUI V2 does not work with the RAK4630/RAK4631
For the RAK4630 there are only two options
Arduino BSP based on the nRF52 BSP from Adafruit
RUI3 BSP which is developed inhouse.
