Hey, I'd like to use the internal MPU9250 with it's internal motion detection interrupt to wake up the Freematics ONE+ Model B. The Interrupt Pin is Pin 12 on the MPU9250. But is it connected to the ESP32? Where does it arrive? In the scheme https://freematics.com/dl/schematics_oneplus_r14_20190612....

Ok, meanwhile I managed to install the freematics builder and was able to build and see the flash memory consumption. WAY below 4 MB.
So, is what the builder shows all the utilization of flash memory I have to expect? (Of course using SD Card, not flash for logging)?

There's a OBD2-parameter 5E: Engine fuel rate [l/h] and 0D: Vehicle speed [km/h]. So, You can do the math:
consumption_per_km = Engine_fuel_rate / Vehicle_speed

I'd think, some more explanation and a more meaningful Topic could be helpful to get answers.

And even more strange: It runs fine under wine on Ubuntu!
But on my Windows 10 machine: neither 1.1.2 nor 1.1.3

Same problem here, with now latest version 1.1.3 running on Windows 10 Pro 64bit.

Ok, I found the setting for the time rate in datalogger/config.h, #define MIN_LOOP_TIME 100 /* ms */ and inside datalogger/datalogger.ino I found the PIDs to log: PID_POLLING_INFO obdData[]= { {PID_SPEED, 1}, {PID_RPM, 1}, {PID_THROTTLE, 1}, {PID_ENGINE_LOAD, 1}, {PID_FUEL_PRESSURE, 2}, {PID_TIMING_...

Hey, can somebody tell me the approximate data rate that the OBD-II/MEMS/GPS Data Logging Sketch for Freematics ONE produces on the SD card? I cannot find a configuration for the PIDs to log and the time rate in which it takes a log point. If I had that, I'd only needed the size of a data point. :-)...

Hey, I consider buying a Freematics ONE+ Model B. Can You people make a recommendation of the flash memory size I should choose? I'm planning not much development, since as far as I can see, everything I need is readily available: - Log (maybe many) OBD live Parameters and GPS Data to SD card - Uplo...
