Hi! I'm trying to use the GCS controller to control my quadrotor, however, every time I activate it, telemetry health always shows a yellow input state in which it says the drone is in failsafe mode. I couldn't figure out where the problem is. I would appreciate the help. Thanks!

Hi,

Quacopter need a external battery/bec/ubec to power the receiver.
If you are using PWM, maybe you have a input/channel configured but no signal received on it.

Do you see something in Input tab about Receiver activity ?
If the issue still, you can redo the transmitter wizard.

I'm currently not using any receiver. Instead I'm trying to use USB telemetry and control through GSC just to see the output PWMs using oscilloscope. I'm not seeing any change on the duty cycles. It's just giving out the neutral duty cycle. I set the input types to GCS in the Input tab. What I'm planning to do is to use Bluetooth telemetry and then control the board through GCS controller. I'm not really sure it is possible to do it without a reciever.

Sorry, i miss the GCS controller information.

Maybe you need to arm the board.
Simply set the arming setting to Accessory0, GCS controller allow arming with iit.

I already did that. No response unfortunately.

I have checked the ObjectBrowser actuator desired tab shows logical values for the inputs coming from the gyros for stabilization as well as for the inputs i give but ActuatorCommand tab shows no change in PWM values.

I don't know what you did wrong.

Maybe you can post the config file.

Newbie mistake

I wonder how you can arm if the Arming setting is set to "Always disarmed"

Except the arming issue your config file is working fine.
No need to setup channels inputs.

Now I see, I thought the arming setting is only the button on GCS controller, didn't notice the huge arming settings tab for some reason Thanks so much for the help.
