No video/telemetry transmission with CSL300 (Ralink rt5572)

[Yes21]

I think my problem is on my airPi and my wifi board (CSL300 - rt5572) So I've connected my hdmi screen on it. The boot is ok, and the wifi board set in monitor mode. But after that, I see a continuous flow of lines which never stops (see joint picture). I never had this problem with the same setup and 1.6rc6 ... That's certainly a specific problem with ralink rt5572, but I've any other compatible wifi board.

Hello, I tried your image during lunch. The video quality was below 1mbs Boot: OK OSD: OK Video: really bad and 2sec latency

Freq: 2312

*I have pi3b+ ground and I had to enable RC-mavlink in the wfb.txt file.

*I also enabled the 5G hotspot in apconfig.txt on pi3b+.

Here is a Dropbox link to my exact config settings for wfb and apconfig.txt

Here's a link to the video, sorry it's very poor quality it was set up in my car. https://youtu.be/wMEOmpY0AME

I hope this helps in some way... On Oct 23, 2018 8:04 AM, "Jelle Tigchelaar" notifications@github.com wrote: I ahve generated a new image based on the lastest Github.

I have no rt5572 to test this with, but i can definately confirm video works with the Atheros cards...

@RespawnDespair please see my notes and video above.

Your image had RC and internal hotspot disabled.

I tested as is and also enabled hotspot RC for the second test.

Both resulted in poor video. *I thought it was the result of an under voltage error but I checked the logs and there weren't any.

EDIT: nevermind, i see you shared it in your post...

I think the version i have included in the overlay/boot folder has some default settings that are not 'optimal'. Even when running kernel7.img on the pi3b+ i wouldn't expect a 2 second lag. RC and hotspot are indeed disabled in the config i now have.

Thanks, What settings do you normally use for the bitrate and quality and cts settings? I don't think what i have there now is optimal... I'd like the default config to be optimized for quality without sacrificing too much range.

[htcohio]

8/4/1024 is the standard default setting that seems to be very reliable for short-range.

And data rate 4

All of this is just the stock video setting except for the frequency. I use 2312 to eliminate any local Wi-Fi noise issues.

Understood, so the defaults in my config are ok, except for the RC and hotspot. I will keep FREQ in the 24xx range for dongles that don't support 23xx range by default.

I hope to hear from user1321 about the Pi3B+ image, i really want to support that, going to order one for myself next week in order to be able to test quicker.

CSL300 is now working.
