Hi,

I have a voxl 2 starling drone and I am running the camera stream using hireses_front_small_encoded inside adb shell via voxl-camera-server -d 0. Its crashing after 5-7 minutes, not sure what it is wanted to send here for inquiry purposes.

Hi, we recently purchased a VOXL2 Drone with this SKU number: MRB-D0012-4-V3-C28-M36-T8-K2. However, we are noticing that it's softap mode connection is intermittent, i.e devices like my computer can connect to it the first time and it stops connecting after that. To fix this, we replaced the wifi card with the AC600 Wifi + Bluetooth Adapter (ALFA Network) and it works smooth. We suspect something is off with the original wifi card the drone came with. I will send a photo here:
