CAN Bus Controller provided on Freematics One+ H

Post by MakersGarage2021 »

Hello,

We would like to know if there is a documentation of the CAN Bus controller used on the Freematics One+ H model.
As we need to mask the data received by the CAN Bus, we need to know details about the specific controller.

Thank you in advance, looking forward to your replies.

Best regards,

Makers Garage :)

You can use CAN sniffing mode to capture CAN data. The controller is not exposed to ESP32.

Hello,
But the CAN sniffing code works only for model B and not for model H. Is there any way that we could modify it so that it can be compatible with model H? We have been using J1939 monitor so far, which worked with model H, but we could only receive the data.

And one more question would be, how to place a request to the ECU using the freematics as we don't see any function related to placing the request in the code, but we only have the function to receive the data.

Best Regards
