Hi,
I can connect my raspberrypi3+ and apsync with QGroundcontrol. Video Streaming is fine working. The Copter is good flying with controller Pixhawk2.4.8.

When I type:
root@apsync:/home/pi# mavproxy.py --master=/dev/serial0 --baudrate 921600 --aircraft MyCopter
Connect /dev/serial0 source_system=255
no script MyCopter/mavinit.scr
Log Directory: MyCopter/logs/2020-09-26/flight5
Telemetry log: MyCopter/logs/2020-09-26/flight5/flight.tlog
MAV> Waiting for heartbeat from /dev/serial0

On my oscilloscope I can see that TX from the Raspi sends a command to RX from the Pixhawk2.4.8, but the Pixhawk does not answer. Where is the mistake?
What must be in MyCopter/mavinit.scr? Is this the problem?

48

Have you set the correct baud rate for the telemetry port on the Pixhawk? It should be 921600 baud and the MAVLink 2 protocol.

49

Thank You for help. I set:
MAV_1_CONFIG 102
MAV_1_FORWARD 2
MAV_1_MODE 2
MAV_1_RATE 1200
SER_TEL2_BAUD 921600

My Rpi3+ make:
root@apsync:/home/pi# mavproxy.py --master=/dev/serial0 --baudrate 921600 --aircraft MyCopter
Connect /dev/serial0 source_system=255
no script MyCopter/mavinit.scr
Log Directory: MyCopter/logs/2020-09-28/flight1
Telemetry log: MyCopter/logs/2020-09-28/flight1/flight.tlog
MAV> Waiting for heartbeat from /dev/serial0

Those don’t look like ArduPilot parameters. What firmware are you using? MAVProxy’s only been tested with ArduPilot.

51

The flight controller is a Pixhawk2.4.8.
Stack: PX4 Pro
Vehicle: Multi-Rotor
Version: 1.10.1
Git Revision: e0f016c2b3000000

52

MAVProxy hasn’t been tested with PX4, so there are likely some incompatibilities there.

53

What can I do?
Under what conditions (Sofware, Hardware) does apsync work?

54

You can look at using MAVSDK or mavlink-router. They are both designed to work with PX4.

55

Hi
the video image is upside down
how can i flip it vertically ?
thank you
Ram

56

There is no option in APSync to flip or rotate videos.

Hi, every thing was working great for few days…
now i have a problem with GPIO14 (tx of the RPI).
i get same problem with 3 Flight Controler that where fine.
i get data bat not read the parameters of the FC (parm list) so can not send command!
is there a way the set other connection as TX (other GPIOxx )?
Thank You

Hello,

I’m following this tutorial: Unlimited range HD streaming with LTE Part 2
to connect to Mission Planner via 4G.

There it says to modify cmavnode.conf. However, I couldn’t find it in the build. Is it renamed?

Please let me know,

Thank you very much!

59

Cmavnode is not included in my APSync build. mavlink-router is used instead.

The two are roughly similar in their configuration, but you’ll need to check the mavlink-router documentation to be sure.

60

Thank you very much!

61

you need add host address “10.0.1.128” in udp link

62

We have the same problem, we tried the bo solution, but we failed, can you help?

Hi Stephen, great work with this image! Is there a somewhat easy way to disable the access point and feed all the data through the ethernet port instead? I don’t have extensive networking knowledge so don’t know if it is possible or not.

Thanks
