Pi Zero Testing about dronebridge

[cglusky]

Great!. I have to rebuild my 300 frame and will give it another try. Might take me a week to get back to it but it is on the list. Thanks!

BTW, It's not going to be Pixhawk/MAVLink so I won't be able to test that part in short term. Going to stick to CleanFlight for my 300 for now. That may change as ArduCopter 3.6 matures since it has more support/docs for F4 type flight controllers.

Hi!
I have never tested a Pi Zero W but think it's cool you would like to try it out!
I have nothing particular in mind right now but keep me posted if something goes wrong :)

I hope to have DroneBridge v0.3 ready by next week with some MavLink telemetry support. Right now the ready to use images only do LTM telemetry and MSP.

[cglusky]

OK. I'll wait for v0.3. Also waiting for some hardware anyway. Will report back here when I give it a try.

It's out now! I am very sorry it took that long but university dropped a shitload of work on me 😒

I have never tested it on a Pi Zero nor with an actual MAVLink FC. I am very interested in how it performs. I am sure there will be issues with MAVLink in some way. Keep me posted an check out the setup guide in the wiki. Posted a sample config that should work with MAVLink over one serial port.

Thanks! No worries about timeline. Still working on frame design. This is for digital FPV on a 300 class frame.

Very impressed with video quality! I see why the wifi broadcast community is so excited.

Setup:
TX: Pi0 with OEM 5572 WiFi card; also connected to PixFalcon via ttyAMA0
RX: Pi3 with Alfa 051NH and AP Hotspot via internal wifi

Results:

• Solid video via HDMI to monitor on RX
• NO Mavlink telemetry that I could see either via HUD in monitor or QGC
• Had video in QGC once but never got it back after a reboot of TX and RX systems

Overall, I am a complete wifi broadcast newb. I followed your instructions in the wiki for the ini settings. Only thing I changed was channel to 5825 and reduced video to 30FPS and stream rate to 12mbit since I am running a Pi0.

Serial settings for control module were ttyAMA0 and 19200 baud to match FC side. I tried both Mavlink v1 and v2 for protocol. I also tried changing telemetry define in OSD config file with no change. Really not sure what files need to be touched to tweak everything.

Also tried the android app on a google pixel. Opens and then crashes when connected to RX hotspot. Assuming I can get an IP assigned.

Hope that helps.

Damn. What android version are you running? Did it crash every time right after startup?

I will fix the MAVLink thing in the next release. It probably is the same issue the guys from Wifibroadcast have with parsing the stream. Next release will have a plain pass through option. That will solve it.

OSD config just tells the OSD what data to exxpect and what stuff to display. Wifibroadcast config is for all the video and transmission stuff. DroneBridge config is for data links, RC etc.
I know it's a mess. Maybe I can solve it in the future

Pixel XL running 8.1. Yep. Open and then crash right after.

[seeul8er]

I added a crash reporting system to the app. If you want I'll post a link here so you can install (& crash) that one. Maybe that gives me more insight on whats causing the problem :)

[cglusky]

Happy to test it.

[cglusky]

Also if you want to mark a 0.3.1 release or some such with your recent MAVLink pass-through changes i can test that as well if you like.

[seeul8er]

Cool! Here is the link to the updated app

Good idea. I'll try to get a 0.3.1 release working till monday.

[cglusky]

App is no longer crashing my Pixel. Will need to hook everything back up and see about video feed etc.

[seeul8er]

Made a new release. Tested it with iNAV.
Set the serial_int_cont to the serial port connected to PixFalcon and just set the serial_int_tel to something that does not exist or disable it on the AirPi by setting en_tel=N.

in osdconf.txt set telemetry type to MAVLink
