On the compass calibration

[seandepagnier]

Thx. Indeed I can run the calibration from openplotter remotely now, but I don't get the yellow dots yet, which, I guess, would be equivalent to a successful calibration and a cue to lock it. The green dot cloud is rather messy. I guess this is due the interaction with the power cable. I'll do this on a swing in the garden another day; the neighbours already think I'm weird.

Avoid magnetic distortions. Normally best to do by rotating the whole boat.

Does this manual remote calibration not interfere with the automatic calibration that also takes place on the Tinypilot image? Can I stop the Tinypilot automatic calibration entirely, and solely rely on the remote, manual one? Or can I visualize remotely the tinypilot automatic calibration process? I want to be able to rely at all times that my compass heading is on the mark. When I see imu.compass_calibration_age set, can I conclude that it's the automtic process that did get a fix?

There is no manual/automatic difference. It recalibrates whenever it can unless locked.

If you see the age reset and the yellow points, it got a fix.

Running pypilot_calibration, I do get some output that suggest something's wrong. Could you cast an eye on that? See attached. I think it's a mismatch between imu.compass_calibration (in the script) and imu.compass.calibration (in tinypilot's signalk). Underscore vs dot in the parameter name.

Thx again!

Your pypilot install on openplotter is too old. You should upgrade it to fix this error.
