I’m working on large fixed wing UAV with auto pilot, but i’m having issues with the telemetry radios.
The radios i’m using are RFD 868-EU, one is connected to my computer, and the other is connected to a cube orange+. My problem is that when both are powered up, with power from the cube and USB cable respectively, they seem to work just fine and transmit data (Both have solid green LED and flashing red LED), however i cannot establish a connection from mission planner to the cube orange, i just get the error message “connection failed“. I already use a baud rate of 57600.
So, mine now works. The issue was with the serial port configuration that the modem was connected to - in my case TELEM 2. I think the baud rates were different between the RFD 900 Tools setup and the ArduPilot serial port config.
Hmmm…you are not mentioned about howto connect the TX to your PC, are you using USB2Serial? or how?
2nd. unless you set differently, the default for RFD868EU are 115200, please set all baudrate (FC PLUS RFD) to that number
yes i’m also use RFD868EU which using Orange Cube also, so should be no problem
This is not a must for you to watch, i just try to show you i’m not kidding
but if you curious please jump to @5:30
Edit:
Please disregard this post
i just remembered i change it to 115200 because to sync to something so yes 57600 is the right default value for the baudrate and also i just realized mine is RFD868UX not RFD868EU
I was running Mission Planner on a Windows 11 emulator from my MacBook. It turns out, that while this solution works fine for most applications, the emulator has trouble with connecting with the hardware on the computer id est sending data on the Universal Serial Bus. I borrowed a Lenovo laptop and i could access the flightcontroller with radio telemetry as intended.
