@Alex-Kushleyev ,
Thank you for your response.

Currently, I am using the MDK-M0062-3-00 board. The reason for using this board is that I previously connected the VOXL and Jetson via Ethernet. However, since there is now only one Ethernet port on the Jetson, I need to use it for other purposes, and there are additional reasons as well. Therefore, I am trying to work using UART.

I have an additional question. Currently, I am using the MDK-M0062-3-00 board, and for the UART port, I am using J9. The UART port is recognized as /dev/ttyHS2, and I am working with it. The voxl-mavlink-server.conf is currently configured as shown in the image below. I would like to know if this setup is correct.

The current VOXL2 SDK is as shown in the image below.

Hello, @Alex-Kushleyev
Thank you for your answer.
I am currently trying to use a Jetson device with MAVLink-router through a UART port.
In this case, is it possible to use PX4 with VOXL simultaneously?
My ultimate goal is to use VOXL while Jetson serves only as a router. I want to achieve this by using the UART port.

Hello, I'm using VOXL2 right now. And I'm using it by connecting jetson. By the way, I want to connect voxl and jetson with uart and use the Wi-Fi function on jetson to run QGC on another PC to get the data. I won't use the Internet for voxl. The image below is an overall block diagram. Is there a way to connect by referring to the block diagram?

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.

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?
