[1113870631]

Yes. By default statistics collection is disabled on the drone side. To enable it add to /etc/wifibroadcast.cfg on the drone:

[drone_mavlink]
stats_port = 8001

[drone_video]
stats_port = 8002

[drone_tunnel]
stats_port = 8003

You need to run wfb-cli gs on the GS side

[svpcom]

You have different wifi channels configured: 1 vs 161

[svpcom]

Set common channel number

[svpcom]

On the drone you can use peer = 'serial:ttyUSB0:115200' to avoid use of mavlink_router

ok thanks it's connected and on the drone i use the ffmpeg to send a udp stream such as :
ffmpeg -f v4l2 -i /dev/video0 -f flv udp://127.0.0.1:5602
the video connect is ok the wfb-cli shows like this

but on the gs i use ffplay udp://127.0.0.1:5600 there is no video windows comes out

is it the video stream no the rigitht formate
what format should i use
and the wfb-cli gs shows the connect is not stable ,it is link lost ，It happens every once in a while，is it normal?

Do you use raspberry pi for drone? If yes, try prebuilt images https://github.com/svpcom/wifibroadcast/releases/download/wifibroadcast-21.08/wifibroadcast_22.2-beta2-rpi3.img.gz

To grab and display video use gstreamer pipelines is preferred.

# display stream on X11 from UDP 5600
gst-launch-1.0 udpsrc do-timestamp=true port=5600 caps='application/x-rtp' ! rtph264depay ! h264parse disable-passthrough=true ! avdec_h264 ! xvimagesink sync=false

# grab stream from UVC camera use software encoder to UDP 5602
gst-launch-1.0 v4l2src device=/dev/video0  ! videoconvert ! video/x-raw,format=NV12,framerate=30/1,width=640,height=360 ! x264enc tune=zerolatency bitrate=4000  ! rtph264pay mtu=1400 config-interval=1 ! udpsink host=127.0.0.1 port=5602 sync=false
