barometric altitude should be logged in csv, not only display.
so it means that the altitude in the csv file is the altitude coming from GPS.
But it will be nice in a future release to also log that barometric altitude (togeteher with other new available values, see other thread...)
1) I've updated the manual on that issue (just connect the GPS and you'll have the HRM also)
2) the barometric altitude is an extra "info display"; it does not influence the GPS altitude
1) do we need to setup 2 COM ports for each features (GPS part and HRM part) of the FRWD B serie ?
2) do you use the data of the barometric altimeter in order to somewhat adjust the altitude information ?
