No heartbeat packets recieved

Hey all,
I’m having difficulties getting telemetry working on my SpeedyBee F405 V3 with a Sik radio. The lights on both radios are solid green and the settings seem to match. I’ve checked baud rates, port config, etc., but I clearly am missing something.

I’ve read through all the forum posts I could find on this topic and wasn’t able to fix it. I’d greatly appreciate any help

Update:
I just noticed that when attempting to connect, the radios both flash red, meaning they are transmitting data, I believe.

Another update:
I managed to get it working with a Pixhawk, but not the F405 V3.

On the F405 V3, it’s connected to the R6 and T6 pins. I figured I might as well set them all to MAVLink2, but still nothing:

And the Sik parameters:
