HoTT
Protocol Number: 57 Autobind: No Channel Re-mapping: No Extended Limits: Yes Failsafe Support: Yes Receiver Match: Yes Telemetry: Yes Option Value: Frequency fine tuning
Frequency tuning is required for this protocol. See the Frequency Tuning page for more details.
Models: Graupner HoTT receivers (tested on GR-12, GR-12L, GR-16, and Vector)
Receiver feature configuration can be performed using the OpenTX script Graupner HoTT.lua.
Basic telemetry is available on OpenTX 2.3.3+ with receiver voltage, receiver temperature, RXRSSI, RX LQI, TX RSSI and TX LQI.
Lower TX LQI values indicate better link quality. TX LQI is a good indicator of how well the module is tuned.
You must use a different Receiver Number for each receiver. A maximum of 64 Hott receivers are supported.
Failsafe must be configured once with the desired channel values (hold or position) while the receiver is up (wait 10+ seconds for the receiver to learn the config) and then failsafe must be set to RX/Receiver otherwise the servos will jitter!

Recommended for best telemetry performance.
Telemetry compatibility mode which can be used when Sync does not work due to an old firmware on the RX.
You should upgrade your receivers/sensors to the latest firmware versions: https://www.rcgroups.com/forums/showpost.php?p=44668015&postcount=18022​
