Additional serial protocol: Graupner HoTT SUMD #2137
Conversation
setting SUMD Failsafe bit is not necessary as it is handled by !frameAvailable
plus some editorial changes
|
Anything else I can do? |
No, it will get reviewed. We're busy getting ready to cut a 3.2.1 release and this change would then be (hopefully) included in 3.3.0 release. |
- removed not necessary changes - moved defines to .cpp file

@pkendall64 Thanks for your review, please see new commit |
|
Yep, lets get this merged ASAP for v3.3 and some testing. |

@JyeSmith Please check new commit |

Looks the good with BF 4.4... cant wait to take it for a rip. |
|
@JyeSmith U own Graupner stuff? |
|
Nup. Just a little tongue in check that'll I'll use it with betaflight. |
|
have at it |
|
Thanks guys |
No probs 😄 Keep the PRs coming if you have anything else in mind. |

Actually there's things on my mind: To be compliant with EU regulations we'd have to implement 868MHz LBT. I say we as I'd need some discussion on how to best do this. And a completely different thing. As there is a vast number of Graupner HoTT telemetry gear available (Graupner OEM, third party like SM's swiss knife Unisene and DIY stuff like openXsensor) it'd be not too difficult to implement a simple telemetry bus master to poll HoTT telemetry devices and downlink telemetry data via the already ELRS/CRSF telemetry packets. All that's required is (soft)serial half duplex communication on a separate pin, the bus master implementation and repackaging of telemetry data to CRSF packets. |

@mha1 ping us on discord in the dev chat 👍 |
SUMD is a serial protocol similar to SBUS which is used by some FCs and a variety of flybarless controllers.
In addition Graupner HoTT receivers can be used as a PWM channel extenders or redundant backup system in dual module ELRS/HoTT scenarios.
