Bob, both those files produce altitude graphs for me. Is there something I'm missing?

When I try to analyze the one flight graph, it becomes a single line, like the image shows. The multi day graph ( with lots of launches) works OK. I assume some header information is probably missing in the truncated one flight data. (clipped from the multi day data set)

Bob, what happens if you click and drag up and to the left (zoom out) on the graph that is not displaying properly? The data files do not have headers. Only the logging interval on the first line. The data looks normal.

The plot is still a straight line. If I clear the analysis it goes back to the normal graph.

The voltage line stays normal, as does the other logged information.
The file 3-9-14 Validol full.bpm works as it should

Be aware that downloader shows less height than what is called out by f3k master.
I have noticed this too....I thought it was something I missed before but I just got back and the F3K master readout is higher than the downloaded file. Is there a fix for this??

Not yet. But Adrian says he'll be looking into it during his next coding session.

I have a feeling it has to do with this line:
return (((Math.pow((((double)basePressure/100)/((double)pressure/100)), 1/5.257) - 1.0) * ((temp/10) + 273.15)) / 0.0065);//sea_press /

The problem with the downloader graphing lower values seems to be to do with the temperature compensation calculations on the data. It comes up with different values for calculations on the device vs in the downloader. I have removed the compensation in the downloader and it seems to be better.

Also, I have fixed the version check as well as the climb rate value (it recorded about half what the climb rate really was). Changing the climb rate units to meters/sec and feet/sec (instead of feet/min) so F3KM takes less time to readout as well as making more sense for this particular application.

New versions to be released after some field testing!

Skyler, the default settings work great.

One setting to note is the Bluetooth TX power.
Set this to a value that makes it connect at the right time as you land. If you have to hold the plane and wait for it to connect, turn up the BT power one step. If it connects too soon, reduce the power.

Also, (if possible) make sure the side with the BT antenna (opposite side to the wire/usb connector) is not completely shielded in carbon.

The rest depends on your setup or what you want it to do.
