Hello everyone,
If anyone has the time to help me around a bit it would be really appreciated, I already spent 2-3 days on this issue and cant find the solution. The documentation on FrSky and radiomaster is garbage.
I got a Tandem X20 radio, I didnt know better when i got into the hobby a few months ago. I want to switch to the elrs system, FrSky being a trash company (i got a drone that is supposed to work with frsky but it doesnt because they switch between protocols like socks and those protocols are not compatible between eachother).
I order to switch to it i got a Gamini TX module from Radiomaster and a DBR4 RX. While i managed to get the modules to communicate, i cant seem to get the channels to work in betaflight. I got both TX and RX flashed with ELRS 3.5.1 . On the radio i got the Lua scripts working, i can see the module, i can access the setup page of both the rx and tx.
The UART ports on the FC seem to be set correctly. I could flash the receiver using BF pass trough. The bind process seems to be right and the receiver tab seems to be set correctly, but i am missing something and could not find the answer.
I will attach some pictures with my setup. Any help would be really apriciated.

This is my BF receiver setup, with the RX/TX on pads for UART6, RX to TX and TX to RX.

Hi Benni, you must have flashed the FC with frsky.
You only have to flash the FC with the Crsf config then you also have stick input.

Yes, make sure you select "CRSF" under receiver protocol when flashing Betaflight

The giveaway is that no bars are showing up on the receiver tab
