Hi

I have a new betafpv micro elrs rx which has servo connections for a fixed wing. it is supposed to work in pwm. After binding successfully to my zorro elrs tx i get telemetry but no servo control on any channel. This seems to be not in pwm mode. Youtube setup tips seem to show settings via wifi but when i go into its wifi setup it looks diiferent and no mention of pwm channels. the software on both the rx and tx is elrs 3.3.0.  

Any ideas please?

Sounds like its possibly got the Crossfire firmware option loaded?

Get the correct firmware from BetaFPV direct and flash that?

Try checking your channels/Mixes

Do you have the correct firmware flashed? It should be "BetaFPV 2.4GHZ PWM RX". Show a screenshot of the receiver's webui.

It's not a crossfire Rx it is 2.4ghz elrs but uses crsf protocol.

There's a "Servos" option in the "Other Options" pull-down of the Betaflight Configurator's Update Firmware page. I suspect you need to rebuild Betaflight with this option selected.

The Lite RX is not a PWM receiver so if you do in fact have the Micro RX then it looks like it has the wrong firmware. You will likely need to reflash the correct firmware. It might be named PWM RX instead of MICRO RX in the ELRS configurator. Otherwise you can download it from Betafpv's website.

Thanks. How does elrs configurator on the pc connect to a receiver?

There are several ways (Betaflight pass through or via UART, you can refer to expresslrs website) but wifi is probably the easiest in your case. You were already on the firmware update page as shown in your screenshot. Just first compile the firmware in configurator for the correct target which will create the bin file. Then connect to the RX via wifi and use the same webpage to load the compiled file.

Many thanks all it's now sorted. For some reason it was supplied with the wrong firmware.
