Great update. I just found this update today. It would be nice to finally get the SOC and SOH this way. For newer EVs like Volvo or th 2021 Polestar this will not work, because setCANID would have to accept 32bit. Typical IDs are 1FFF0010 for example. I'll give it a try with a Volkswagen next week, ...

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

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...

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...

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...

Awesome! Thank you!

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...

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...

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.

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 & ...
