Problem with RAK4631 bootloader update

Hi, I purchased some RAK4631 modules from RAK for a new project, I used Arduino IDE on Windows for code and while it compiled ok, on the download it came back with possible bootloader version mismatch - see attched error.
So, then I tried to update the bootloader using adafruit nrfutil and it came back with same error as attached. Questions ; do the RAK4631 modules from RAK come pre-loaded with RUI3 firmware and the latest bootloader ? How do I read the firmware versions that is on the module ?

Welcome to the forum @socie

There are two Arduino BSP’s for the RAK4631
Community driven BSP
RAKwireless RUI3 BSP

From your log I see you are using the Community driven BSP. That doesn’t work with a device that has a RUI3 bootloader.

You need to install the RUI3 BSP as shown here ==> RUI3 Supported IDE

Thanks Bernd, I will try the RUI3 Arduino version…
