Good day

I am working on the Setinel VOLX2 platform and I am having issues working with QGC. There seems to be an unstable connection to QCG from the drone.

The wifi connection from the PC to the drone stays constantly connected. However, I see that the drone status on QGC continuously cycles from *Ready To Fly* to *Communication Lost*. 

The log on QGC is depicted below:

I am also noticing that my RAM is also running out when I have QGC connected. Could this issue be related to the log that keeps running continually?

Can you run ```voxl-version``` and report what version of software you are running?

I thought this screenshot would give a better indication of the communication issue between the drone and QGC

@TPSetati When you say that your RAM is running out, is that the RAM on the computer that is running QGC or on the VOXL2? For the connection issue, what are you using as your wireless link?

## Reply by TPSetati · 2023-04-11 07:56:10 UTC

I mean the RAM on the host PC running QGC. I can't have QGC open for more than 5 minutes without the machine freezing up.

I am using the drone in softAP mode and connecting to its WiFi.

That sounds like a qgc issue. Have you reached out on the PX4 Discord?

## Reply by TPSetati · 2023-04-11 14:13:27 UTC

No, I have not. How do I reach out?

I'll try them out. Thank you.

@TPSetati Is there a chance you have two ground stations trying to connect to the drone at the same time?
