I want to know the DIRECT usage of wfb_rx wfb_tx wfb_tx_cmd wfb_tun

[archfelix]

I want to use wfb-ng to transfer some custom message.
for example, I want to use two RTP server, and transfer RTK data.
I dislike the service-based and python tool chain.
Could you please provide an example of a primitive tool?

Sample scripts:
https://github.com/svpcom/wfb-ng/blob/master/scripts/rx_standalone.sh
https://github.com/svpcom/wfb-ng/blob/master/scripts/tx_standalone.sh

Thank you very much! But I got some new problems.

[archfelix]

I started wfb_tx and RTP program to send h264 encoded data to 127.0.0.1:5600
It shows:

radxa@rock-3a:~/third/wfb-ng$ sudo ./wfb_tx -p 0 -u 5600 -K drone.key wlan0
Listen on 5600 for wlan0
940130  LISTEN_UDP_CONTROL      55829

And on my laptop, I started wfb_rx:

felix@felix-laptop:~/third/wfb-ng$ sudo ./wfb_rx -p 0 -c 127.0.0.1 -u 5600 -K gs.key wlxfca3860f0e6a

7198880 PKT     0:0:0:0:0:0:0:0:0

It seems that RX can NOT receive TX.

I have set the 8812au to monitor mode, and both of them are set to same channel.
On drone:

radxa@rock-3a:~/third/wfb-ng$ sudo iw dev wlan0 info
Interface wlan0
        ifindex 3
        wdev 0x1
        addr 1c:a7:70:e7:44:ca
        type monitor
        wiphy 0
        channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz
        txpower -1.00 dBm

On gs

felix@felix-laptop:~/third/wfb-ng$ sudo iw dev wlxfca3860f0e6a info
Interface wlxfca3860f0e6a
        ifindex 2
        wdev 0x1
        addr fc:a3:86:0f:0e:6a
        type monitor
        wiphy 0
        channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz
        txpower 5.00 dBm

Most of 8812au cards are 5GHz only. Also ensure that networkmanager, wpa_supplicant and other are off.
Run tcpdump to ensure that you actually inject and receive packets

[archfelix]

Wow! Thank you very very much!!! It works. I forgot to turn off NetworkManager.
By the way, I think the primitive tool is very useful! It is much more flexible than Python Tools, and it can expose the low-level interface.
So I think it should not give up the primitive tool. There are still many developers in need of this.
