RUI3 for Rak3172

Hello. i bought rak3172-t module, but it doesn’t provide choosing channel.

So, I need the old RUI3 firmware for RAK3172-T (TP) module.
Is there anyone who has RUI3 firmware?
Pls share RAK3172-T_RUI3_V1.0.2.hex for development.

Welcome to RAK forum @jotgildong ,

The FW can be found on the datasheet.

What issue do you encounter related to choosing channel? Maybe it is not a RUI3 version issue but something else.
