Hott telemetry protocol

Hi all,
i need some help…
i’m using with success an APM 2.5 with 3.0.1 firmware modified to enable the Hott telemetry on my Graupner mz18 radio.
Now i would like to upgrade to Pixhawk board… Is there a chance to enable the Hott telemetry like on Frsky sistem?


currently, the only way to to this is to translate mavlink to HoTT using a device from
-This is mostly because Pixhawk’s OS does not allow UART to disable RX pin on a UART while sending bytes, and HoTT uses bidirectional serial.
