Freematics Forum

The reason is I am doing a project at my university, where there have to be specialized logging. This requires GSM and GPS module, as well as gyroscope and such. The Freematics has almost all of these things, but is way cheaper for a small production. They are looking for around 25 units, where the ...

According to the schematics, the protocol controller is using the stm32f103c8t6 microcontroller to interface the gps and CAN-bus, where the CAN-bus is through a tja1050 can transceiver. OBD2 has support for both direct CAN sniffing but also the call/respond you describe. I would like to alter the ...

Hello, I would like to be able to broaden the use of the Freematics ONE. In order to do this, I would need access to the STM32 protocol processing microcontroller. Can the software running on this be altered using the Arduino connection or in another way, with some soldering possible?
And if this ...

Thank you for your reply.

What goes trough the obd port is manufacturer dependent. I know for a fact that some cars, uses a double can bus system, where the obd will be connected to one can bus system and will request from the other can bus system. As you described. Other cars, on the other hand ...

Hello

I've been trying to get raw data from the can bus to the serial output, using datalogger as an example. However, datalogger seems to have a filter so it only sends out the pids that was requested. I would like to have either the entire can bus frame or something divided in ID and data, for ...
