I have a mamba f722 app flight controller I just installed and it’s hooked to the caddix vista the FC comes set to 9v by default but for some reason I don’t have any battery voltage showing in my goggles. I first used the wiring harness provided with no luck then soldered everything and still nothing. What am I missing please help thanks

make sure rx is going to tx and tx to rx. also check the ports tab in the configurator and make sure its set on the correct uart

Check if the wires are broken
