I would say you need to write your own code for that: I had a very quick look at the library and I didn't find an option to do it.
See https://github.com/stanleyhuangyc/Multi ... D/UTFT.cpp and related files.

AFAIK, no: one pin is not connected and another one is used to control GPS power.

Is this a followup to your earlier post?

Do you still have this issue?
I have noticed that datalogger will happily record OBD data during the first run after booting.
When I park the car and later restart the engine, only the GPS data is recorded, not my selected PIDs.

Not with the UBX-M8030 that comes with the One+, since it has a 10Hz update rate:

I don't think this is currently possible, at least in the field.

I don't think you can monitor either of those values: when it comes to oil, you can only monitor the temperature but not the pressure or the level. There probably isn't even a sensor to monitor them, to begin with. Tyres are a different issue: there is a sensor and the car knows about it for sure. P...

If you don't mind having the timestamp only once per cycle, here is my solution:

It's not yet in the official tree but you're welcome to try it out, if it helps.
(this applies only to the Datalogger sketch, of course)

Hmm, right now the isValid method returns true when the PID index is above 0x7F which makes no sense to me: there is no space to map supported PIDs above that number and also no transcoding of values in the library.

Good thing I increased the minimum cycle time in datalogger from the default 100ms to 250ms.
I'm going to try to raise it further.
