Hi there! Pop OS 6.1.11-76060111-generic #202302091138~1675975749~22.04~f771a7f SMP PREEMPT_DYNAMIC Thu F x86_64 x86_64 x86_64 GNU/Linux here. HW: TL-WN722N v2 card with this fix. Airdump-ng works fine - tested it.

[jeanlemotan]

The problem seems to be this: 0:1(10): error: GLSL 1.30 is not supported. Supported versions are: 1.00 ES, 3.00 ES, 3.10 ES, and 3.20 ES Can you comment this code and try?

    if (glsl_version == NULL)
        glsl_version = "#version 130";
    IM_ASSERT((int)strlen(glsl_version) + 2 < IM_ARRAYSIZE(g_GlslVersionString));
    strcpy(g_GlslVersionString, glsl_version);
    strcat(g_GlslVersionString, "\n");

It's in the imgui_impl_opengl3.cpp file, line 107.

[Yury-MonZon]

Commented this block out. And I get this:

[Ncerzzk]

can you test with sudo tcpdump --monitor-mode -i wlxac15a2eb4253 I'm sorry that I know little about Airdump-ng generally in my test case, if the tcpdump operating netcard works fine, gs can work too.

[Yury-MonZon]

Sadly, it doesn't work this way: tcpdump: wlxac15a2eb4253: That device doesn't support monitor mode I think I can try to fix it later on.

But the main problem here is that I'm not passed the video issue yet. Would really appreciate your help here: sudo -E DISPLAY=:0 ./gs (I) src/PI_HAL.cpp: 286: Drivers: 4 (I) src/PI_HAL.cpp: 289: Driver 0: x11 (I) src/PI_HAL.cpp: 289: Driver 1: wayland (I) src/PI_HAL.cpp: 289: Driver 2: KMSDRM (I) src/PI_HAL.cpp: 289: Driver 3: dummy (I) src/PI_HAL.cpp: 298: Mode -1: 947570897x1420212923 (E) src/PI_HAL.cpp: 317: Cannot create window: No available video device (E) src/PI_HAL.cpp: 604: Cannot initialize display Segmentation fault

Thanks a lot!

[Ncerzzk]

please exec printenv to get your DISPLAY info first and try sudo -E DISPLAY=XX ./gs replace XX to your display,example: :0.0

[Yury-MonZon]

No video problems so far. Thanks. I'll try to find my monitor mode problem. $ sudo -E DISPLAY=:1 ./gs (I) src/PI_HAL.cpp: 286: Drivers: 4 (I) src/PI_HAL.cpp: 289: Driver 0: x11 (I) src/PI_HAL.cpp: 289: Driver 1: wayland (I) src/PI_HAL.cpp: 289: Driver 2: KMSDRM (I) src/PI_HAL.cpp: 289: Driver 3: dummy (I) src/PI_HAL.cpp: 298: Mode 0: 1366x768 (I) src/Comms.cpp: 718: Radiocap header size: 11, IEEE header size: 24 (I) src/Comms.cpp: 581: Opening interface wlxac15a2eb4253 in monitor mode (E) src/Comms.cpp: 623: Error in pcap_activate: That device doesn't support monitor mode

[Yury-MonZon]

Just to be sure: I should see beacons and acknowledgements, right? Then it works fine with sudo tcpdump -l -i wlan0 (not sure about -L key) after I put it in monitor mode with my script.

[Ncerzzk]

why remove --monitor-mode option?

[Yury-MonZon]

Because I have to put my card into the monitor mode via script. Can you provide some info on what tcpdump prints out on a properly working setup?

[Ncerzzk]

sudo tcpdump --monitor-mode -i wlxac15a2eb4253 just a command to test whether your netcard could be operated well, it would put your card to monitor mode automatically(if it support), you don't need other script. if it runs ok(no error), you can directly use sudo ./gs.

[Yury-MonZon]

Tcpdump can't put my card into monitor mode for some reason. I have TP-WN722N v2. But after I put my card manually into monitor mode I can run sudo tcpdump -i wlxac15a2eb4253: `sudo tcpdump -i wlxac15a2eb4253

[Ncerzzk]

gs didn't contain tcpdump. tcpdump for me is just used for test netcard.

try to remove if (pcap_set_rfmon(pcap.pcap, 1) < 0) https://github.com/jeanlemotan/esp32-cam-fpv/blob/adc1e5c040bada4780de0db60716af411d326435/gs/src/Comms.cpp#LL599C9-L599C23

[Yury-MonZon]

Thanks a lot! Now I'm getting somewhere - I can see the GS screen with HAL menu.

But sad news - my camera is borked, so I'll have to wait for a new one (confirmed with another code as well).

Is there an easy way to make esp32 send dummy frames(like the camera is there) so I can play with the link range etc?

[Ncerzzk]

you can package a static jpeg into c header, then send it by call camera_data_available manually
