When does logging start

[paulbutcher]

This feels like a stupid question, but I can't find anything definitive anywhere in the documentation.

When, exactly, does logging start?

I've got an RCP2 with integrated telemetry. I *think* I'm right in saying that, if I have telemetry setup and "background streaming" on, logging is streamed whenever the RCP2 is powered on?

What about logging to the SD Card? Am I right that this is controlled by the start/stop logging button on the RCP2 itself and/or the startLogging/stopLogging Lua functions? Is that it, or is there anything else?

So, given that the RCP2 is installed somewhere I can't reach it from the driving seat, if I want to log to the SD Card as well as to race-capture.com, I will need a Lua script which will start logging whenever (say) speed as determined by GPS exceeds 10mph?

Assuming that that's how I have things configured, is there any benefit to having background streaming on?

Background streaming controls whether data is streaming over the telemetry link all the time (background streaming = ON) or only when logging (background streaming = OFF).

Aside from manual start/stop you can control automatic logging using a Lua script.

There are a number of different approaches - speed, engine on/off -etc. We asked this question a few days ago on our FB page. What would be your preferred approach?

Thanks - I think that confirms that my understanding as expressed in my original message is correct?

Right now, I'm just trying to work out what the situation is. I've not really thought about what it *should* be yet

Correct as in there's a lot of ways to interpret how / when to start logging; that's why we didn't bake it in as a formal firmware feature.

Let us know your thoughts! Clearly we're narrowing down on a few candidates.
