@RyanH , from the spin log above, i can only tell that the motor attempts to spin up but re-starts after the open-loop sinusoidal spinup is done and the ESC detects that the motor is not spinning.

You should try to clear the debris by spinning the motor by hand first (or use compressed air) and then use the test script to spin for longer periods of time without propeller (changing speeds, etc).

You could use a spin step command to automate increasing and decreasing spin speed (without rpm control, since it's not needed):

./voxl-esc-spin-step.py --id 0 --step-delay 2.5 --step-frequency 1 --power 20 --step-amplitude 30

@Alex-Kushleyev , thanks! We'll give it a try and let you know how it goes.

Hello @RyanH ,

The GPS interference work is still ongoing. Currently, the solution that works is elevating the GPS using a mast with some shielding right under the mast, as described in the thread you referenced.

We recently added a feature to voxl-portal to allow you to see the individual satellite signal strengths in order to help with debugging the signal quality. The GPS page can be located under the Debug section of voxl-portal, you should get the recent nightly build of voxl-portal in order to try it.

Elevating the GPS receiver by about 4 inches with shielding has shown to completely eliminate the interference, but you will also need an extended cable that plugs between the GPS receiver and VOXL2.

If you need more details about the workaround, I can prepare better documentation and I'll see if we can have replacement cables or extensions available to make the electrical connection easier.
