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::beg...

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 probl...

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-dat...

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
