Calibrate Altimeter

The way to calibrate altimeter in my FR645 is to start an activity and wait for GPS, start, stop and discard. ok so far.

How to implement in an own app? I mean I'm only doing sessions with my own app and not using activities.

Should be the same with a CIQ app, or it was in the past. Start up GPS in your app and there should be a calibration when it gets a 3d fix.

But I just heard yesterday from a user that there may be a bug with the current FW on the 645.

I've the feeling, that since latest FW update of 645 it is working if I'm starting my app (which activates GPS). Because we have a stable air pressure at the moment, I cannot prove, but will observe ... thanks for feedback :)

Update: Can confirm, now works with latest update (5.20).
