+ Version 1.0.1 is a major release, adding support for the TeleMini + device and lots of new AltosUI features +

+ AltOS Firmware Changes +

+ Add TeleMini v1.0 support. Firmware images for TeleMini are + included in AltOS releases. +
+ Change telemetry to be encoded in multiple 32-byte packets. This + enables support for TeleMini and other devices without requiring + further updates to the TeleDongle firmware. +
+ Support operation of TeleMetrum with the antenna pointing + aft. Previous firmware versions required the antenna to be + pointing upwards, now there is a configuration option allowing + the antenna to point aft, to aid installation in some airframes. +
+ Ability to disable telemetry. For airframes where an antenna + just isn't possible, or where radio transmissions might cause + trouble with other electronics, there's a configuration option + to disable all telemetry. Note that the board will still + enable the radio link in idle mode. +
+ Arbitrary frequency selection. The radios in Altus Metrum + devices can be programmed to a wide range of frequencies, so + instead of limiting devices to 10 pre-selected 'channels', the + new firmware allows the user to choose any frequency in the + 70cm band. Note that the RF matching circuit on the boards is + tuned for around 435MHz, so frequencies far from that may + reduce the available range. +
+ Kalman-filter based flight-tracking. The model based sensor + fusion approach of a Kalman filter means that AltOS now + computes apogee much more accurately than before, generally + within a fraction of a second. In addition, this approach + allows the baro-only TeleMini device to correctly identify + Mach transitions, avoiding the error-prone selection of a Mach + delay. +

+ AltosUI Changes +

+ Wait for altimeter when using packet mode. Instead of quicly + timing out when trying to initialize a packet mode + configuration connection, AltosUI now waits indefinitely for + the remote device to appear, providing a cancel button should + the user get bored. This is necessary as the TeleMini can only + be placed in "Idle" mode if AltosUI is polling it. +
+ Add main/apogee voltage graphs to the data plot. This provides + a visual indication if the igniters fail before being fired. +
+ Scan for altimeter devices by watching the defined telemetry + frequencies. This avoids the problem of remembering what + frequency a device was configured to use, which is especially + important with TeleMini which does not include a USB connection. +
+ Monitor altimeter state in "Idle" mode. This provides much of + the information presented in the "Pad" dialog from the Monitor + Flight command, monitoring the igniters, battery and GPS + status withing requiring the flight computer to be armed and + ready for flight. +
+ Pre-load map images from home. For those launch sites which + don't provide free Wi-Fi, this allows you to download the + necessary satellite images given the location of the launch + site. A list of known launch sites is maintained at + altusmetrum.org which AltosUI downloads to populate a menu; if + you've got a launch site not on that list, please send the + name of it, latitude and longitude along with a link to the + web site of the controlling club to the altusmetrum mailing list. +
+ Flight statistics are now displayed in the Graph data + window. These include max height/speed/accel, average descent + rates and a few other bits of information. The Graph Data + window can now be reached from the 'Landed' tab in the Monitor + Flight window so you can immediately see the results of a + flight. +
