Hi, Mr. Bonkers here......
Step 1: unplug ESC signal connection to APM 1.4
Step 2: plug in Lipo (beeping starts)
Step 3: plug in USB cable
Step 4: Use Mission Planner to connect to Quad and start fiddling with stuff
I just would like to use the Mission Planner plugged into my Quad for setup, without that constant beeping! Is there a way to turn it off?
The quad is calibrated and flies OK using 2.5.3 . I am trying to set up my Turnigy/ 6 Mode switch in the Setup page and between trying to follow a YouTube video on this, and the incessant beeping it is driving me batty.
You might want to make this simple mod to your APM board:
This also powers the RC receiver from the USB, so you won't need to connect the LiPo for radio tests.
Thanks Dave, I will take a look at that.
I guess I could also plug in the receiver with a separate battery pack, to power that. I was thinking there might be some kind of common ground required for that, provided by the lipo power. But I'll give it a try.
This does not work. The APM and receiver need a common ground.
The other thing you could do is pull the ESC connections and then plug in a _spare_ ESC which does not have a motor attached to the outputs. That way you won't hear it complaining, since the beeping is generated by the connected motor.
Running it straight off the USB may pose problems depending on the current draw of your receiver. But a spare ESC should provide a quick and easy source of +5V.
I've measured 20mA current drain for a Turnigy 9-channel receiver, which I'd imagine that would be typical for most receivers. That shouldn't be an issue for USB.
On my quad, with APM (1.4 with compass), telemetry, receiver and sonar, I've done the mod and it powers up from a Netbook, Notebook and Desktop without problems.
However, if you're trying to drive servos (say Pan/Tilt), that would cause a problem for the USB supply.
