Hi,
I just got a Cube orange and tried to connect it to the Herelink as well as to a companion computer (JETSON NANO DEV KIT). With both systems I can not establish a serial connection and thus also get no heartbeat when installing px4 1.14.3. It all works well when I install Ardupilot but I can’t get it working with px4.
The companion computer is connected with Telem2 to the serial port of the Jetson Nano. The Herelink is plugged into Telem1. I have enabled both ports using QGC and also tried different baud rates, all with no success.
I have tried different firmwares still without success. The cube also doesn’t detect the Herelink (RC input nor UART). But everything works well when I flash Ardupilot on it.
I still had no luck getting this to work. Have you seen anything similar @JulianOes in the past?
Try with an FTDI cable instead. I could not get my Jetson’s serial port to work properly, and I have seen multiple reports online of electrical issues with the Jetson’s serial port.
Thank you for your reply Julian!
I have tried connecting with a FTDI cable. Still with no success. Interestingly I can establish a connection to the Jetson when I first plug in the TELEM cable of the Herelink and then swap it with the TELEM cable of the Jetson. I assume there must be some sort of issue in setting up the initial connection.
Flow control is set to off, right?
Yes, I’ve set Flow control to off. But still with no luck. At the moment I still only get it to somewhat work with the Herelink when I use Ardupilot. With PX4 it does not connect through either of the two serial ports.
When I want to read telemetry using MAVSDK with Ardupilot I get the following read out on MAVLINK:
Request was for msg ID: 242
heartbeats timed out (system_imp.cpp:265)
sending again after 1.01687 s, retries to do: 2 (520). (mavlink_command_sender.cpp:320)
sending again after 1.51937 s, retries to do: 1 (520). (mavlink_command_sender.cpp:320)
Discovered 3 component(s) (system_imp_.cpp:509)
this continues over and over again.
Ok, what’s the MAVSDK version?
