Hello,
I just updated my D2 Charlie to firmware 5.00 (CIQ 3.0.1).
Has anything changed in regards with the :altitude field when accessed through Activity, Position or Sensor.Info ?
PS: Maybe the issue at hand was already present in firmware 4.20 (given the known elevation issues raised in the forums), although I pinpoint it only now
When I use the Garmin Altimeter Widget, I read a (Calibrated) altitude of, say, 400m.
When I use the Garmin FLY App, configured for Pressure Altimeter, I read an altitude identical to the Garmin Altimeter Widget
When I use the ConnectIQ GPS Metrics Widget, I read an altitude matching the two former (I don't know what Toyboy source it's using though)
When I use my GliderSK App, I read an altitude of 445m, taken from Position.Info :altitude.
No going back-and-forth from the aforementioned widgets/apps changes anything.
Has anyone experienced the same discrepancy ?
Are all three Activity, Position or Sensor.Info :altitude source still supposed to give the same reading, namely "Elevation is derived from the most accurate source: Barometer or GPS in order of descending accuracy. If no GPS is present, then barometer readings will be used" ?
Also, when reading about Activity.Info :ambientPressure, I see a mention of "The data is smoothed by a two-stage filter to reduce noise and instantaneous variation".
This sounds strangely close to the numerous reports, in the Wrist-Worn section, about Altitude readings being delayed and smoothed.
This is obvious in one of my activity: https://connect.garmin.com/modern/activity/2900207608 ; enlarging the elevation graph and looking closely at time 1:35:30, one can see the altitude reading obviously switched from one "mode" to another.
Do you ConnectIQ guys would see some explanation to that change ?
Regards
