Hello everyone i would like a help in connecting the OMNIBUS F4 V6 tx and rx to the RP4

I understand that in the fc you need to connect to the serial1 - telemerty1 - USART1 and i did do that. but for some reason when i try to connect with mavproxy it gives me no link.

i have checked everything the wires, solder and it should work also here is a diagram where i soldered the rx tx:

Is this V6 or V6.x? UART1 likely won’t work if 6.x, see the Ardupilot documentation of the board.
