Freematics Forum

i dont know specifically but if it is available you could find out how from the datasheets for the sensor/modules in there, just google it

well assuming you have the logger model with ble instead of 2.1 then you would just change the baud rate i specified

ATMA may not necessarily be supported with your car (or elm327) it doesnt work for me with them.

Did this work for anybody? I want to use a bluetooth serial terminal app on android to send and receive data to the logger, but did not manage to get a connection.

it works for me, you will need:

#define ENABLE_DATA_OUT 0
#define STREAM_BAUDRATE 38400 //assuming 2.1 bt
#define VERBOSE 1

then ...

yes i can see that bit in init now, thanks for pointing it out.

the reason i did it my way is that i had already tried those pid supported requests with a elm327 and they dont seem to work correctly with my car. thus my manual method.

Here's a little sketch that uses freematics obd library to go through the list of pid's and report back which ones are supported by your car.


#define SD_LOG
#define LAST_PID 128
#define DEBUG Serial3
#define DEBUG_BAUD 115200
#define LOOP_DELAY 500 //milli delay between pid's

#include <Arduino ...

sounds like it, though yo want to check how well your car supports obd.

try having a look here and see what you can find out (i tried compiling that code and got same error, so not you) https://github.com/stanleyhuangyc/ArduinoOBD/issues

try to contact freematics directly

what code are you trying to load ?
