2 way communication #20

Closed 09Ria09 closed 3 years ago

09Ria09 commented 6 years ago

Hi! Is 2 way communication possible? I want to send MSP messages from the air to the ground and vice versa. Is that possible? Also, what's the difference between Radio Port and UDP port?

@svpcom Hi! Do you use any specific kernel or you just use the latest one?

svpcom commented 5 years ago

@09Ria09 For rtl8812au - any kernel because it use external driver

09Ria09 commented 5 years ago

@svpcom I was asking because on this EZ-Wifibroadcast page they say:

it's strongly recommended to use kernel 4.9.35, as this one has been extensively tested with EZ-Wifibroadcast and has turned out to be stable. Other kernel versions may have whatever issues that are not directly apparent, for example USB timing issues that lead to higher packetloss or instabilities that are hard to reproduce and may only show up under certain conditions or after many hours of running.

Also should I do this?

Put these options (in exactly that order!) at the end of cmdline text: dwc_otg.fiq_fsm_enable=0 dwc_otg.fiq_enable=0 dwc_otg.nak_holdoff=0 dwc_otg.int_ep_interval_min=0

svpcom commented 5 years ago

@09Ria09 I don't use Raspberry PI for WFB. My primary target is NanoPI NEO2. So for RPI you should follow EZ-WFB kernel selection guideline.

@svpcom Recently I tried to install wifibroadcast in Ubuntu, it's supposed to connect to 14550, but it doesn't work properly. When the drone(raspberry pi) is off and I run nc -lu 14550,I get this output:

�   t�m��d���   u�m��d�[�   v�m��d���   w�m��d�O�   x�m��dY��   y�m��dI#�   z�m��dh��   {�m��dx7�   |�m��d;��   }�m��d+
                                                                               �~�m��d

Do you know what could cause this? NetworkManager is already disabled. Also this only happens when wifibroadcast is started.

@svpcom Here is a part of the tcpdump's output when wifibroadcast is started:

Nevermind, I forgot about RSSI injection.

09Ria09 commented 5 years ago

@svpcom Hi! I tried to change the resolution from 480p to 720p, but then the video loses lots of packets and it stutters a lot. Here is the video command before: raspivid --nopreview --awb auto -ih -t 0 -w 720 -h 480-fps 48 -b 4000000 -g 48 -pf high -o - | gst-launch-1.0 fdsrc ! h264parse ! rtph264pay ! udpsink host=127.0.0.1 port=5600 and after: raspivid --nopreview --awb auto -ih -t 0 -w 1280 -h 720 -fps 48 -b 4000000 -g 48 -pf high -o - | gst-launch-1.0 fdsrc ! h264parse ! rtph264pay ! udpsink host=127.0.0.1 port=5600

Is it too much data for 2.4G? I don't think it's the channel because I used this: sudo iwlist wlan0 scan | grep Frequency | sort | uniq -c | sort -n, which tells me the channels used in my neighborhood, and the channel I selected(channel 2) doesn't appear in the list.

svpcom commented 5 years ago

It may be hardware or linux distro issue. See for reference: https://github.com/svpcom/wifibroadcast/issues/36

09Ria09 commented 5 years ago

@svpcom I've changed my setup, now I have a raspberry pi zero on the drone and a raspberry pi 3 on the ground connected to a laptop running Windows 10 via ethernet. The raspberry pis' are running both raspbian, I've installed kernel 4.9.35 as recommended by EZ-wifibroadcast, but I didn't apply any patches(one patch disables watchdog and another is for one way only, the rest are for other cards), and I also added dwc_otg.fiq_fsm_enable=0 dwc_otg.fiq_enable=0 dwc_otg.nak_holdoff=0 dwc_otg.int_ep_interval_min=0 at the end of the cmdline text.

09Ria09 commented 5 years ago

@svpcom Can this be a driver/kernel issue? I will try to use kali linux on the raspberry pi today.

svpcom commented 5 years ago

First try with both usb wifi sticks attached to the linux PC. Use ubuntu 18.04 or Fedora 27 or later. For arm boards i've tested it on NanoPI NEO2 (Armbian Stretch with 4.19.xx kernel). Use driver from https://github.com/svpcom/rtl8812au (v5.2.20 branch)

09Ria09 commented 5 years ago

@svpcom On the PC running both drone and gs Ubuntu it works better, I still get packet loss, but only around every 7 seconds and only around 8 packets each time.

I used these commands to test on my pc: gst-launch-1.0 -v videotestsrc ! video/x-raw,width=1480,height=720,fps=48,codec=h264,type=video ! videoscale ! videoconvert ! x264enc tune=zerolatency ! rtph264pay ! udpsink host=127.0.0.1 port=5602 and gst-launch-1.0 -vc udpsrc port=5600 close-socket=false multicast-iface=false auto-multicast=true ! application/x-rtp, payload=96 ! rtpjitterbuffer ! rtph264depay ! avdec_h264 ! fpsdisplaysink sync=false async=false --verbose (and sudo wfb-cli gs)

Use driver from https://github.com/svpcom/rtl8812au (v5.2.20 branch)

Would this help me? My network adapters use RT3070.

EDIT: If I use wfb drone on the raspberry pi zero and wfb ground on the PC, I have almost no packets lost(although it feels slightly laggy). So the problem is the raspberry pi on the ground.

svpcom commented 5 years ago

rtl8812au is for realtek 8812/8814au. For RT3070 use builtin ralink driver You should limit h264 bandwidth (for examle for 4Mbit x264enc tune=zerolatency bitrate=4000) to fit into your wifi channel bandwidth (for MCS#1 is ~7Mbit)
