Softap issues
-
Hello
We are experiencing issues when connecting via wifi. We setup the voxl-wifi on 5ghz and it will work great for a while. Eventually, after a few days with minimal changes it will stop working. We can ifconfig wlan0 down and up again to get some signal, but it is very weak.
The things we have changed is all on the px4 side and the camera configs, so nothing with softap specifically other then setting it up.
We keep getting to the point where we factory reset the drone and then it works again for a few days. Any advice or assistance would be beneficial.
Thank you

Hello @jeremyrbrown5 ,
Can you please answer the following questions to help us diagnose the issue?
- Which wifi adapter are you using?
- Does rebooting VOXL2 Mini help?
- How are you measuring the connection quality?

@Alex-Kushleyev Apologies for the delayed replied. We have mostly resolved our softap issues. I'm not sure which wifi adapter we are using, I believe its whatever comes in the developer kit. When we run into the error, rebooting the mini doesn't help, the only part that works is factory-resting. As for connection quality, its very much relying on the icons visual bars.
What we determined is that the more changes config files and the more services we have operating at once increases the chance that softap will just not work. Since we have been messing with custom yolov8 models, we have been moving and removing .txt and .tflite files from usr/bin/dnn, and if everything is even a little bit off, we have the issue. Now we are pretty ok though.
So, I guess its resolved, but in a very hand-wavy kind of way.

@jeremyrbrown5 , it is possible that overheating VOXL2 cpu could be causing your SoftAP performance slowdown. You can run
voxl-inspect-cpuwhich is a tool that will show you cpu usage, temps and other stats. If the CPU cores reach 95 deg C, the thermal management will slow down the cpu clock, so all the processes will run slower, including SoftAP.Alex
