Hello Everyone! I am having trouble with my first FPV build. I have a BetaFlight ELRS 2.4GHz Lite Reciever and RadioMaster Zorro transmitter. Both have been updated to ELRS 3.3.0. They seem to connect, as the receiver has a solid blue light, and the Transmitter shows a "C" in the LUA script. When the power of the drone is disconnected then connected, the transmitter says "Telemetry Lost" and "Telemetry Recovered". In beta Flight, UART 2 is set to serial, and protocol is set to "CRSF". In Betaflight, no movement is detected in the reciever tab. I've attached photos of my wiring and transmitter. Please help!

thanks 

EDIT: Added photos

SOLVED: WIRES WERE SWAPPED

the photos arent vidable, try to upload them again ore use somthing like igmur to provide a link to a photo

Please post clear, well lit photos of your wiring between the flight controller and the receiver. I’m not actually seeing pics of that in your first post.

In case you weren’t aware, a common mistake folks make is to mess up the wiring. TX on the receiver goes to an RX pad on the flight controller, RX on the receiver goes to a TX pad on the flight controller.

Since you’re using uart2, that would be:
ELRS RX - Flight Controller
TX ———-> RX2
RX ———-> TX2

Swap the yellow wire and the white wire positions on the flight controller.

You’re currently going rx to r2, and tx to t2.
Needs to be rx to t2, and tx to r2.

Easiest way to remember this (for the way my brain works at least):
RX = Receive
TX = Transmit
If one board is transmitting (tx), then the other board needs to receive (rx), and vice versa.

You’re welcome. I did the same damn thing when I first started. Happy flying!
