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.

1. AltOS

AltOS new features:

-Add support for TeleBT -

AltOS fixes:

-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). -
-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. -

2. AltosUI Application

AltosUI application new features:

-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 another. -
-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. -

AltosUI application fixes:

-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. -
-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. -

3. AltosDroid

-First version of this application -
