- 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. -
