Can the browser display be updated to have the barometric pressure displayed in the field as well as what's currently there? Just a thought!
At the moment it prints the following
Pressure Altitude (BMP) | Enabled (Auto) QNH=1025mb QNE=-124ft GNSS=229ft
As already discussed the QNH is estimated based upon the relative GPS/Baro Altitude.
Are you asking for the Barometric pressure from the sensor ?
If so that is not easy, the sensor is modal, and can be configured for Altitude, or Pressure.
So it would need re-initializing and then require settling time to perform the calculations for each reading
so in effect you would need to do the following
Initialize for Altitude
Settle ...
Read Altitude
Initialize for Pressure
Settle ...
Read Pressure
That would take quite some time I think, I guess it could be run in a separate thread so as not to impact the main thread.
What is the reasoning behind the question ?
