Re: changing the ECU response ID's in OBD

Would also be interested in this, as it is the same in my EV.

Re: Reading EV Data - how?

The best way to read Data from modern vehicles (like BMW i3 from 2013 onwards, VW ID Series, Volvo, Polestar, etc..) would be a function like frame obd.readPID(request_ecu, request_frame, response_ecu) (just dreaming here) This way, we could retrieve all the information like SoC, Battery Health, Cur...

Re: Reading EV Data - how?

Hi Paolo, both ways don't work because you cannot send CAN messages by this. For example, to get the odometer reading, you send a CAN-Message to (for ID-Series) 0x17fc0076. The vehicle will respond immediately with the odometer reading. But ReadPID cannot do this. Which is really annoying. Because y...

Reading EV Data - how?

Did anyone manage to read EV data with a 29bit Bus with the ONE+ Model H? There are a lot of questions around this on this forum, but none has a response. My goal is to get the SOC and other data from my EV (like the various ELM327 apps around in the appstore). I know what CAN message to send on the...

Re: CAN-Bus access from ESP32 (One+)

Thanks for looking into this. It will help me a lot in my project. My customer just placed an initial order of another 10 dongles just to try. My prototype "hack" is to solder a TTL converter to the external pins and then back to 6/14 of the OBD2-Port - to send the command via the ESP32 in...

Re: CAN-Bus access from ESP32 (One+)

Any idea how to accomplish this? It could even be with a sequence of AT-commands, whatever works to send a CAN-Message. It would also help to set the vehicle into diagnostic code. I had great success using the One+ to collect the odometer and VIN from my Polestar and the Tesla by just using the snif...

Re: CAN-Bus access from ESP32 (One+)

Thanks for the quick reply. Something like this:

268#0010000000000000

That's for example the command to physically close the doors of my Tesla; a very "visual" test. No authentication needed beforehand.

Re: CAN-Bus access from ESP32 (One+)

Thanks. I was convinced that there must be a deliberate thought behind it. I just need to send a single message to the CAN-Bus, is there any best practice on how to do this? (Background Info: I need to collect odometer readings for a fleet tracking application; the dongle works fine for Tesla & ...
