New Features

  • Supported "Passthrough FrSky Telemetry" from Ardupilot (protocol 10).
  • The frequency at which position data is received is shown on the display (i.e. LTM from iNav is sent at 5Hz).
  • Automatic home from aircraft telemetry without local GPS.
  • Baro altitude supported for FrSky D protocol

Ardupilot Passthrough FrSky Telemetry

It is a open protocol available in ArduPilot that allows the transmission of raw data to OpenTX based transmitters, and it is optimized specifically for the FrSky datalink bandwidth. Read more about this protocol at Ardupilot Passthrough FrSky Telemetry website.

In order to use this protocol in the configurator you can activate the AUTODETECT feature or select the FRSKY X protocol in u360gts-configurator and, in addition, in CLI window you have to execute this command:

set telemetry_provider=APM10

Telemetry Frequency on Display

Data field Hz: is shown on display with the value in hertz at which telemetry position data is arriving at the tracker.It will help to us to get a better idea about how fluid is the position data stream. As an example, when using LTM protocol, iNav sends position data at 5hz, which ensures fluid tracking and good user experience.

Automatic Home from Telemetry

Thanks to this new feature local GPS is needed no more for auto tracking (unless you are planning to pilot your aircraft from a mobile platform like a car or a ship, in that case local GPS is mandatory becaus the tracker home position have to be updated continiously), and no button have to be pressed in order to set home position from telemetry ().

In order to use this feature you have to disable local GPS and set AUTO mode to telemetry_home parameter:

feature -GSP
set telemetry_home=AUTO

Note: If you want to set home manually, leave telemetry_home parameter value as DEFAULT.

You also have to set telemetry_min_sats parameter with the desired number of sats as the condition necessary for home position to be set:

set telemetry_min_sats=6

Please, be aware that the tracker will never know which is the home position that the autopilot has set for the aircraft because no frame from the telemetry stream that might carry it on is processed.

The procedure to set home automatically is described bellow:

0 - Tracker and Aircraft have no power.
1 - User powers the aircraft.
2 - Aircraft set its own home position.
3 - User checks information displayed on his ground control software or OSD data.
4 - User thiks that he has a good and stable gps signal and decide that it is a good moment to power on the tracker system.
5 - The tracker receives telemetry data from the aircraft and if the "min number of sats" condition is overcome it will use the next lat/lon data arrived as home position.

Baro altitude for FrSky D protocol

For a better precission in altitude, BARO_ALT_BP_ID packet from FrSky D telemetry protocol is parsed.

Upgrading from previous version

  1. Be sure to run the latest u360gts configuration release (download from here).
  2. Download the hex file for your controller board.
  3. Select baud rate, connect and press CLI ENTER button
  4. Go to Cli Mode tab, press BACKUP Config and save the configuration file.
  5. Press BOOT MODE button.
  6. Run Flash Loader Demonstrator (download from here.)
  7. Select port, baud rate, and next.
  8. Browse and select the hex file, select Global Erase and Jump to user program options, and next.
  9. After flashing close Flash Loader Demonstrator.
  10. Go to u360gts configurator, select 115200 bauds, press Connect and CLI ENTER buttons.
  11. Go to Cli Mode tab and press RESTORE CONFIG.
  12. Save and you are done.

After this you are ready to connect and enter CLI Mode in order to configure the new features.

Installing for the first time

  1. Download the latest u360gts configuration release (download from here).
  2. Download the hex file for your controller board.
  3. Turn on your controller board in "boot mode". For NAZE32/Flip32 you have to bridge boot pins before giving power.
  4. Run Flash Loader Demonstrator (download from here.)
  5. Select port, baud rate, and next.
  6. Browse and select the hex file, select Global Erase and Jump to user program options, and next.
  7. After flashing close Flash Loader Demonstrator.
  8. Run u360gts configurator, select 115200 bauds, press Connect and CLI ENTER buttons.
  9. Follow the instructions to configure your tracker.
