Version 1.2.1 is a minor release. It adds support for TeleBT and
the AltosDroid application, provides several new features in
AltosUI and fixes some bugs in the AltOS firmware.
AltOS Firmware Changes
Add support for TeleBT
In TeleMini recovery mode (when booted with the outer two
debug pins connected together), the radio parameters are also
set back to defaults (434.550MHz, N0CALL, factory radio cal).
Add support for reflashing the SkyTraq GPS chips. This
requires special host-side code which currently only exists
Correct Kalman filter model error covariance matrix. The
values used previously assumed continuous measurements instead
of discrete measurements.
Fix some bugs in the USB driver for TeleMetrum and TeleDongle
that affected Windows users.
Adjusted the automatic gain control parameters that affect
receive performance for TeleDongle. Field tests indicate that this
may improve receive performance somewhat.
Handle missing GPS lock in 'Descent' tab. Previously, if the
GPS position of the pad was unknown, an exception would be
raised, breaking the Descent tab contents.
Improve the graph, adding tool-tips to show values near the
cursor and making the displayed set of values configurable,
adding all of the flight data as options while leaving the
default settings alone so that the graph starts by showing
height, speed and acceleration.
Make the initial position of the AltosUI top level window
configurable. Along with this change, the other windows will
pop up at 'sensible' places now, instead of on top of one
Add callsign to Monitor idle window and connecting
dialogs. This makes it clear which callsign is being used so
that the operator will be aware that it must match the flight
computer value or no communication will work.
When downloading flight data, display the block number so that
the user has some sense of progress. Unfortunately, we don't
know how many blocks will need to be downloaded, but at least
it isn't just sitting there doing nothing for a long time.
Add GPS data and a map to the graph window. This lets you see
a complete summary of the flight without needing to 'replay'
the whole thing.
