monitor mode? #1

Closed QiXuanWang closed 5 years ago

QiXuanWang commented 5 years ago

After driver installation, do I need to set the wifi into monitor mode? Or if the wifi is working then everything is done?

svpcom commented 5 years ago

Wifibroadcast will do this itself.

QiXuanWang commented 5 years ago

I see. Any reason the LED is off? Do I need to configure something?

svpcom commented 5 years ago

what is output of sudo journalctl -x -u wifibroadcast@drone or sudo journalctl -x -u wifibroadcast@gs ?

QiXuanWang commented 5 years ago

I didn't start the service actually. I'm testing the video link. Let me try to run the service and report back.

... So it's actually failed to decrypt. It's weird. I'm using the key pairs generated by TX RPI's wfb_keygen. I'm using scp. Anything that I should pay attention to??

svpcom commented 5 years ago

Try to run TX and RX (wifibroadcast@gs and wifibroadcast@done) on the same machile (for example on PC with two wifi card connected) and run test video source and sink through it. tx video:

gst-launch-1.0 videotestsrc ! videoconvert ! video/x-raw,format=NV12,framerate=60/1,width=1280,height=720 ! clockoverlay time-format='%s' ! x264enc tune=zerolatency bitrate=4000   ! rtph264pay config-interval=-1 ! udpsink host=localhost port=5602

rx video:

gst-launch-1.0 udpsrc port=5600 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264' ! rtph264depay ! vaapih264dec ! clockoverlay halignment=left valignment=bottom time-format='%s' ! vaapisink sync=false

Also try to generate a new keypair.

svpcom commented 5 years ago

Attach journalctl full log (from daemon start, not only last lines)

svpcom commented 5 years ago

Run wfb-cli gs to see realtime monitoring

  1. Check link with both cards on PC (not on RPI) using videotestsrc with bitrate 4mbps
  2. If WFB on PC works, then check card power (connect directly to +5v, not to USB +5v, becase RPI usb power is too weak)

OK.... I'm glad I bought a testing 9271 wificards :) This one works perfectly fine except for slow refreshing speed for RX. I think which could be improved by gst-launch settings.

So the problem should be 8812au driver. I'll see what's wrong with it...

The second point makes sense though with EZWifi it still works with same testing condition.
By "card power", do you mean power RPI through GPIO power pins or did I misunderstand?

No. USB 2.0 is 0.5A max (by spec). It is ~2.5W. Some arm boards have weak usb power chain and high-power load (like 1w wifi card) can overload it. I recommend to connect its usb +5v pin directly to +5v rail and add low-esr capacitor like ESC has.

Thanks. I read about this problem at EZWifi wiki page but since my ASUS ac56 card worked with the testing image I thought it was OK. The USB on wifi is 3.0 but since RPI USB is 2.0, the power problem should still be there.

I'll close this issue as it's mainly power problem.

It's possible to change the USB modeswitch behaviour. Take a look https://github.com/kimocoder/rtl8188eus/commit/74161a96518ec08741ec7dd6082dab9f92b44e2b on howto

This can be done in runtime via rtw_switch_usb_mode=0 module arg or just use usb2 data cable.
