Here's the up to date spec for ArduPilot's Passthrough:

We're in the process of updating the ArduPilot wiki for its passthrough telemetry implementation: https://github.com/ArduPilot/ardupilot_wiki/pull/635 In particular, there's a spreadsheet with the spec: https://docs.google.com/spreadsheets/d/1HIfioe-EGTOtH5rOdexGlAz2E5HnCvZLm0EG6rfjNSI I'll make ano...

Both our modified 3.3.3 and the official rc5 sends (when using passthrough - SERIAL#_PROTOCOL = 10): - GPS MSL altitude in decimeters on ID 0x1002 for our modified 3.3.3 and ID 0x5002 for official rc5: https://github.com/craftandtheory/APM_FrSky/commit/31b4e1661e591bacafa98495adc38756d40f0b2e#diff-4...

$7 USD/mo is to get private repositories. You can compile for free...

Email [email protected] and I'll send you the firmwares... Just so you know, though, the FrSky passthrough protocol is only in rc5.

Oh, a question was asked "which version did the APM log creation stop working correctly?" So I would need compiled versions. Just as 3.4-rc5 is now. I would be more than happy to run those tests for you all - (I used to be a HP Protect Tools software functionality tester a while back). So...

Standard IDs are already implemented in the stock firmware and no special version is needed, anybody can use that already. Absolutely. It's the protocol #4 (SPort) in ArduPilot which has been around for a little while now (as far as I know, at least since Copter 3.2). That protocol uses all standar...

My main question is why values are being passed in the 'special' IDs (1000-1007) when, for some values, there is a standard ID for them. A specific one is GPS altitude, this is 0x0820~0x082f and the value is a signed 32 bit integer in cm. Using the 'special' passthrough value causes a resolution pr...

Hi,

I'm the dev for the OpenTX Passthrough protocol in ArduPilot. If you have any question about it, I'd be happy to answer them here...

By the way, you should probably use the latest protocol which is found in the official ArduCopter 3.4-rc5 (or same in master branch)...
