Are you connecting via direct cable connection to the Pixhawk or via Radio telemetry. If its the latter, I would try connecting via direct cable for troubleshooting. Also, what happens when you try to connect via the “Connect” button at the top right of MP?
Also, I would try a baud rate of 57600 and see if that fixes anything.
That error in terminal means nothing. Even if you pick the same port as seen by Device Manager that error will occur. What are you trying to do with Terminal?
What happened with Motor Test? That is self arming no need to do it manually.
Sorry … I was thinking of testing the motors manually. Did take your advice and chose “Motor Test” from the MP menu. Would not work … error message that came up was “Command was denied by auto pilot” . That must mean something but not exactly sure what.
The safety switch needs to be pressed down for motor testing. If it says denied again, quickly switch back to the flight HUD and see what error it is saying.
Did that, thanks. Tested the motors and was able to get a tone sound. It seemed that the tones came only from one motor. Will Isolate the other 3 when testing for one.
Each motor should spin individually as you trigger them in the motor testing screen. The letters are as follows:
Motor A: Front Left
Motor B: Back Left
Motor C: Back Right
Motor D: Front Right
You might have to increase the throttle % input to around 10-20% to see any motor movement. If the motors still do not spin at 20% or more then there the Autopilot is not connected to the motors. Can you send a close-up picture of your autopilot hardware?
Do the ESCs/motors make any sort of sound when you unplug and plug the wire into the main out ports of the Pixhawk? Also, does the aircraft have a battery installed?
If there are no sounds when unplugging and plugging the wires back into the main out port then the ESCs are not getting power or you have plugged in the ESC cables upside down into the Pixhawk.
Here is a thought. Either I am missing something very obvious or … as a noob I bought this from Banggood at a good price. As time has gone on I’ve picked up it may not be “original” Pixhawk goods but rather clone. Maybe I should have gone with a product from Holybro etc and from a reputable dealer like GETFPV? I think I’ve got junk equipment here. Like they say , “If you pay peanuts, you’ll get monkeys”
Interesting. That either means the ESCs are not powered or that they are not receiving any signal from the Pixhawk. Just want to double check that you have the battery currently plugged in and powering all the ESCs?
Next step might be taking out a multi-meter and measuring the voltage of the signal rail on the Pixhawk. This will let us know if those ports are still operational.
