I have the zubax GNSS 2 and I’m struggling to get it working with a pixhawk v1 on APM software.  
I read that for APM I need to configure a unique device ID. Is that correct? If so, how do I proceed?

I am surprised by lack of documentation for this…

Sorry if this is a noob question.

Ok I figured it out. For future reference :

For windows via USB:  
Install STM32 Drivers ([STSW-STM32102 - STM32 Virtual COM Port Driver - STMicroelectronics](https://www.st.com/en/development-tools/stsw-stm32102.html) you may have to do it manually), download and install PuTTY.  
In PuTTY use the following:  
Enter your COM Port  
Baudrate: 115200

After you’re connected execute the following:

```auto
cfg set uavcan.node_id 50

```

```auto
cfg save

```

```auto
reset

```
