I have been using In-Flight on both my laptop and pda and in both cases I get no altitude information. The gps unit is a cheap one from Maplins which connects via bluetooth.



I monitered the incoming messages on the com port and get the following:



$GPGGA,081925.000,5134.2084,N,00022.1493,W,1,06,1.3,63.5,M,47.0,M,,0000*7C

$GPRMC,081925.000,A,5134.2084,N,00022.1493,W,0.19,114.94,310510,0,,A*4E



AFAICS the altitude is correctly reported in the GPGGA message as 63.5 metres. Why does this not display ?

I've never seen one that doesn't. One customer did have one that didn't, but discovered that there was a message that needed to be sent to the GPS chipset to tell it to output all messages, and sending this message before running SkyDemon solved the problem.
