Graupner Hott telemetry

I wish to have the telemetry of radio Graupner MZ-16 but its displays nothing.
I put the requested settings, but nothing works.

  • [SERIAL1_BAUD] set to 19 (for 19.2KBaud)
  • [SERIAL1_PROTOCOL] set to 27 (HOTT)
  • [SERIAL1_OPTIONS] set to 4 (Half Duplex)
  • [BRD_SER1_RTSCTS] set to 0 to disable flow control (optional)

I tried on different ports

Anyone to help me???

Graupner radios are really rare there are very few people use them with ardupilot so there really arent many people that can help you unfortunatly. Last time i set one up was over 4 years ago

Thank you, but then why include an option that does not work??? Even for a rare radio at 700€ lol

I never said it doesnt work, just that there are so few people using them that you will struggle to find somone to help you.

If your still stuck, this is the converter i used last time I had to use a graupner radio with Ardupilot just set the port for mavlink 1 and it should work.

Do a search on the forum for “hott telemetry doesn’t work at all” and post in that thread. Some say it works others not.
