This is an inquiry regarding RAK3172.
I used the previous version, but this time I am using RUI3 version (4.0.6).
At the time of purchase, the firmware version was 4.0.0, so I updated it to version 4.0.6.
The firmware was updated normally, but an issue occurred in several modules (6-7 out of 100)
where no output came out of the UART port when power was applied.
The upgrade was performed using the STM32 Cube Programmer.
I was wondering if there were any known bug reports regarding this phenomenon.
I’m also curious if there is a way to factory reset the internal settings.
