In open Tx is there a way to send serial data over the Telemetry channel to the receiver. To program a device remotely? While I have not dug though the source code yet, I was hoping to ask here to save myself some searching. Also is there a Doc somewhere on the telemetry protocol used?

Thanks,
Brad

You might want to say what radio you're using, what RF hardware etc...

Wow... I was just thinking about this very topic. Hursto75, are you talking about being able to remotely program a flybarless controller with something like the jeti protocol?

Anything possible with this idea? The msh brain will soon be offering "jeti integration" and it would be great if we could do that on a radio that doesn't cost $1400

It's being worked on with the FrSky protocol.

Sweet! Thanks.
Is there a thread you can point me to, or is it still too early..

It's in the developer chats for now. We're currently only at the level of figuring out how it can be done.

Hi Hexperience, look at tool from FrSky named SP2UARTConverter, maybe this will solve You problem.

It's not that I have a problem I'm trying to solve or anything like that. I'm just looking to see if true 2-way serial communication is possible through the s.port, but it looks like serial only goes 1 way. The TX sends RC control data, and received Serial data, so we can't send serial data to a flight controller.

2-way serial is possible over the SPort. The limitation is the throughput.
If you have two of these "FrSky S.Port to UART converter with 2 ADC ports (SP2UART)", then you plug one into the receiver SPort and the other into the Tx SPort and you get two way serial between them, but limited to 30 bytes/sec or so.

Mike.

The FrSky modules and system make it possible, but there is nothing done in the radio firmware to make use of it at this point. There will be in OpenTX 2.2.

Interesting, 30 bytes per second is enough to make a change to a flight controller. If 2.2 adds some ablity to control that via lua scripts there might be something that can be done along those lines. (Pun intended )
