I received my bridge today (cheers Dave!) and have just put the whole PilotAware together on my RP2. I updated the software to 20160530.
However, when I look at the web page, I'm seeing strange values for QNH and QNE. The QNH is currently showing 1305mb! I don't think this is right. Either my barometric sensor is a bit out or there are some sums being done incorrectly somewhere.
Hmm, just looked, now showing QNH 1313mb, QNE=-8156ft, GNSS=154ft.
The GPS altitude looks fairly sensible for here.
Can I ask those who have the Bridge to have a look at what values it gives for QNH?

Hi Paul
Pi2 with bridge sitting on window sill reporting 1016 QNH against local (EGPH) ATIS reporing 1015QNH.
It does wander a mb or two when it is inside but usually pretty consistent.

Bridge been very good here +/- 1 mb using Blackpool and Warton QNH.
I have notice if the pressure change is very slow, electronic sensors
are slow to react, compaired to a quality manufactured mercury barometer.

Paul,
Mine's reading 1017mb at present which is about right for EGPH. Haven't heard of any other reports of dodgy readings, so unlikely to be software. Looks like you've got a dodgy unit.

Installed my new bridge last night and its reporting QNH=1016mb QNE=230ft GNSS=322ft, pretty much as expected (Doncaster showing 1014).

Sounds like a hardware fault doesnt it ?
I presume a cold restart (power disconnect) does not cure it ?

Hi Paul,
PM sent, could you drop me an email at the pilotawarehardware email address if you've not received it.
cheers
Dave.

Got it, thanks Dave.
No, a power reset doesn't fix the issue. I'd be up for soldering on a new baro sensor, but I might leave that bit up to you! :D
