Hello,
I use Tinker 3S with latest Tinker OS.
I connected a high-power USB 3 camera module (800 mA).
At the same time, my Tinker board is periodically accessed over Wi-Fi by a web client (it runs a web server).
When I cut the power to the Wi-Fi router, the USB camera capture suddenly starts failing in bursts. This is reproducible.
If I disable Wi-Fi power saving mode (see attached code), the problem disappears.
echo "options 8822ce rtw_power_mgnt=0 rtw_ips_mode=0 rtw_lps_level=0 rtw_low_power=0" \ | sudo tee /etc/modprobe.d/8822ce.conf
However, I would like to avoid disabling power saving mode if possible.
What do you think is happening here?
