Freematics Forum

Hello Miguel,

you are not alone. I have 2 loggers and have problems, too.
The Freematics Datalogger is only able to read data via CAN 11/500.
I guess the firmware of the STM32F has a few bugs.

that's an interesting question.
the decoder code could be useful

Hello Stanley,

I still couldn't fix the problem.
To be sure, it's not a hardware fault, I ordered a second datalogger.
I am still only able to communicate via CAN 11/500.

Is it possible, that I set the Baudrate wrong?
- First of all I set Serial.begin(9600); in the setup-method.
- Then, in COBD ...

Same problem here.
Works only with CAN 11/500 .
Has anybody found a solution?

Glad to hear, I´m not the only one
Are you working on a solution?

I use an older version of OBD-library and V2 and get a successful initialization to CAN 11/500 and KWP2000.
But I´m only able to read Data via CAN 11/500

Can somebody connect successfully to OBD?
I still have problems.
I figured out I can´t connect to obd via any protocol since the last update.
I use firmware V3.
With one of the older versions of the OBD-library and firmware V2 I was able to connect only to CAN 11/500.

Does anybody have similar ...

No. Unfortunately, I notice no difference.

It works just for one of the cars I tested (I tried the logger with 7 different cars).
On this car I get one CSV-File per test drive.

When I try the same with other cars, it works unstable:
1) Sometimes I get one CSV-File per test drive, but without OBD ...

Hello Stanley,

I updated the last OBD library and still have a few problems with the OBD connection.
I don´t receive OBD-data from every car. I tested it with many different (newer) Cars.
Does anybody else have the same problem?

Thanks
