VOXL2 RC uart failure
-
We are currently using VOXL2 products.
I'm connecting voxl-elrs now, but elrs is not recognized.
I have several voxl2. When I connect elrs to another voxl2, it recognizes the connection. But the other one is not recognized. It seems to me that the elrs uart port is broken.
So I don't use GNSS so I want to connect els using that port.
Is there a way? -

Is there a way?Hi @tkddnjs825 ,
Can you please provide more details:
- which ELRS receiver are you using?
- which connector / port are you connecting the receiver to?
- does the receiver appear to power on (LED on, etc) when you connect it to VOXL2 that is unable to communicate to it?
- does the same receiver work on another VOXL2?
- how exactly are you testing ability to communicate to ELRS receiver?

Hi @Alex-Kushleyev ,
Q1. which ELRS receiver are you using?
A1. I am currently using BetaFPV Nano RX.Q2. which connector / port are you connecting the receiver to?
A2. I'm using port J19 for VOXL2. It is connected to ports 1, 10, 11, and 12.Q3. does the receiver appear to power on (LED on, etc) when you connect it to VOXL2 that is unable to communicate to it?
A3. The receiver is powered on because the LED is on and the controller binds the receiver to display the antenna.Q4. does the same receiver work on another VOXL2?
A4. Yes.Q5. how exactly are you testing ability to communicate to ELRS receiver?
A5. It's time to fly by connecting to another VOXL, and it comes out exactly when you scan voxl-elrs --scan, but in the problem voxl2, when you scan voxl-elrs --scan, ERROR comes out. -

Can you please confirm that it's not running on the voxl2 board where
voxl-elrsis not working?I will also forward this question to my colleagues who should have more info.

In addition to Alex's question above, could you also please share which version of
voxl-elrsis being used on each voxl2? Thevoxl-versioncommand should list the versions of each installed package.Can you also please confirm that in the voxl-px4 configuration file on the voxl2 that is not able to communicate with the ELRS receiver that the RC type is set to CRSF_RAW, like this:
RC=CRSF_RAW.Furthermore, if you could share the output of
voxl-elrs --scanfrom the voxl which is unsuccessful that would be helpful.Thanks,
Max
