I ordered rak3172-T radios, they have RUI 4.0.6. When I change the baud rate to 9600 it doesn’t save it. When I restart the radio, it has the default baud rate of 115200 again. This is a big problem because I use the Arduino pro mini controller software serial and it cannot work with 115200 baud rate. The previously ordered rak3172 radios worked correctly, i.e. stored the baud rate setting. Why does the T version not save the baud rate value?
Welcome back to the forum @TimoVee
That is strange, the bug with the not-saved baudrate was fixed in RUI3 V4.0.1
Can you reflash the latest RUI3 firmware, which is V4.1.1 and check if the problem is still there?
Yes, I know this issue.
I found version 4.1.0 here:
https://downloads.rakwireless.com/#RUI/RUI3/Image/
where can I find the 4.1.1 version?
I tried downloading the 3172-E version to the radio, and that baud rate works correctly. (otherwise it probably worked as it should)
Now I have the T version of the radio.
Still missing in the Download Center, it was released a few days ago.
You can get it from here ==> RAKwireless-Arduino-BSP-Index/RUI_4.1.1_282/RUI_4.1.1_282_release_firmware.zip at staging · RAKWireless/RAKwireless-Arduino-BSP-Index · GitHub
The same thing, the baud rate is not saved.
I don’t have a RAK3172-T, only the “normal” ones.
I will report this to our R&D team.
ok, these are new to me too. I need to get this working as soon as possible, I hope there is a quick solution to this.
