I reflashed my RM Nomad as RX by copying the nomad TX target json file and editing the RX/TX to 3/1. After referencing the correct RX unified firmware, it is working fine. The TX and RX are communcating and there is RC outputs detected on the flight controller.
What I currently have an issue is that when using the ELRS script on the transmitter, the "other devices" sub-menu is missing as I want to adjust the power output.
