Hi:
I flew my Telemetrum v1.2 system today with the Altus Droid connected to
the Teledongle via USB.
The flight was good. Went to 6887ft and only had about 1/4 mile to walk
for recovery.
A couple issues though.
The altimeter did not record the entire flight in the flash memory. Only
the first 75 sec of the flight was recorded. The entire flight time was
several minutes. When I go to save the flight data using the AltOS
application on a computer the download errors out with:
"Flight 8 download error invalid checksum at 0x100000 Valid log data saved".
So, this kind of makes sense because I had the Max Flight Log Size set
to 992 (2 flights). So, if I understand right, it would use only the 1st
MB of the 2MB storage for the flight (no other recorded flights). And
0x100000 is the 1MB location where the data probably just ends.
But at this point in time I can find no way to actually delete that
flight from the altimeter and also the Maximum Flight Log Size selection
in the Configuration panel is greyed out and disabled. I don't remember
for sure, but does the UI normally give the option to delete after you
have downloaded? Since it is erroring out, I'm not getting that option.
What am I missing here? Do I understand the cause of the problem
correctly, or should I be at all worried about a flash failure?
The second issue is that during the recovery phase, the Altus Droid
application as it was giving me the voice updates kept saying "Speed
0.0" and never anything different than that. So first question is, is
that supposed to be vertical speed or horizontal speed? We had so little
wind today that it really didn't move very much horizontally, so if that
is what is being reported, then it might make sense. But if that is
supposed to be vertical speed, then maybe there is a bug there.
Lastly, I know that the Altus Droid saves the telemetry data to the
Android file system. Is there any way to then get the droid app to load
one of those files and replay it like you can with the AltOS computer
app? Or at least get the flight stats? I would find it useful at times
to be able to load one of those files on the phone and at least see what
the basic flight stats were.
Thanks!
Steve
