Navio2 - Unable to calibrate ESC's after upgrade!

After installing the upgrade, to be safe I ran through all the calibrations. I am unable to calibrate the ESC’s. Also I have not commination with the ESC. Before the upgrade I didn’t have any issues with calibrating the ESC’s. Is anyone else having this issue?

Hi @bobbyl8133,

We’ll check what could be the issue here. In the meantime, could you please specify what Raspberry Pi you’re using?

I"m using raspberry pi4 4g

Were you able to duplicate the issues?


I had a look at ESC calibration on my Hexa, Navio2, RPI 4 with latest kernel. Arducopter is 4.07.

ESC are beeping but there is no calibration signal.

Hi everyone,

Thanks for the details!

At the moment, we’re investigating this issue. I’ll let you know as soon as there is any news.

Hi there,

We’ve reproduced this issue with Navio2. If you need to use the device for flights at this point, please reflash your SD card and don’t update the packages in order to bypass this issue. I’ll write back once we have a fix for it.


Any updates on the ESC calibration issues?

Hi there,

We’ve deployed a new kernel. It should fix the issue with ESC’s calibration.

Please run the sudo apt update && sudo apt upgrade for the update.
