Graupner HOTT telemetry doesn't work at all

ArduCopter Copter 4.0
21

Hi anyone succeed to use Graupner Telemetry? I updated my copter to 4.04 RC firmware but it doesn’t work. All settings are set ok:

Sorry for bothering but I telemetry is essential for me and I have to decide to work with Graupner or buy another transmitters and receivers. I need it for my work. I have also problems with Mavlink to HOTT converters, some interference which disables the HOTT telemetry.

edit:
As I understand it will be fixed in next release:

Dear all,
having the same issue.
Was trying to activate HOTT telemetry on ArduPlane and failed while following this setup guide: HOTT Telemetry. Also tried out different ports. No sensors showing up at all.
My setup is F765 wing, GR12 + MZ 18 transmitter.

Thanks in advance for your support.

Guido, Hott telemetry works with copter 4.0.4rc3.
You have to set the serial port to half duplex and flow control has to be disabled

Hi, thanks for the reply.
Does that mean, with plane its not supported yet?

Guido, this is the Copter section of this forum,so my answer related to the copter version.
I’m not sure about plane, but the release-notes say that it has been integrated in “Release 4.0.6beta1, 23rd May 2020”. So may be it’s not in the stable release yet.

Ah, maybe, I’m using 4.0.5. Thanks for clarifying!
Strangely, wiki telling that it should work from 4.0.0

maybe I will give beta a try.
