Frsky D8 and Graupner Hott not works on Ethos 1.5.15

[fdapport]

Module hardware: IRX4 Lite modulo 4-In-1 2.4G Multi
Firmware Module: mm-stm-serial-reta-air-v1.3.4.0
Radio hardware: Frsky X20S
Firmware radio: Ethos 1.5.15

it work great with Hitec receivers and V761 receiver.
I am not able to set Frsky D8 receiver ( V8FR-II) and Graupner receiver (GR16), see attached picture.
What protocol I need to select? I have try Frsky D8 and Graupner Hott but not works. Could please help to set it. Thanks,
Franco

Both receivers should work well with the latest firmware and these protocols:

https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/Protocols_Details.md#frskyv---25
No idea how Ethos works,..

I have try as well with a taranis X9d+ 2019 and the Miltiporotocol module, Openx Tx version 2.3.15, multiprotocol version 1.3.4.0. same result, both receivers NOT Working with frskD8 and Hott protocol. Could somebody help me. Thanks

Have you done the frequency tuning as indicated in the protocols ? https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/Protocols_Details.md#frskyd---3

I have try a couple of values with any signal/connection, if you thinks this could resolve the problem I need to do more values and see if a could bind it.

[pascallanger]

As indicated, you need to try to bind with 0, -40, +40.
After I don't know your frsky Rx , since it's a V8 so I would have say it's frsky v protocol but...

[pascallanger]

Also, what are the module LEDs doing before, during and after bind?

Finaly I the V8FR-II works with Frsky-V protocol as sugested!!! Thanks... Hott is not working also with fine tune procedure , do you know if I ned to load some LUA script to alow Hott works? Please let me know...

[pascallanger]

There is no lua to run for the bind. Hott should work, try different values of freq tunning and try at different distances from touching the antennas to a couple of meters. The RX listens to the tx and the tx to Rx.

what about the receiver firmware, could be relevant for the bind process? Thanks for your help.
