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.

Notes

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!

Sub Protocols

Recommended for best telemetry performance.

1 - No_Sync

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
