datalogger /api/live shows 0 for all PIDs

Postby rosch » Mon Mar 18, 2019 8:21 am


i have just received my ONE+ and trying to get it to work with the "datalogger" example.

- customization and flashing succeeded
- ONE+ is starting, loading firmware and connecting to WIFI (i can see this in the serial console)
- to connect to the OBD i have to turn the ignition key, otherwise i get only _____
is there a chance to get ODB data while parking, i want to check the battery SOC while charging in the garage (yes i have a IONIQ PHEV)?
- via /api/live i get 1438 for the "battery" so it seems that data is being read, unfortunately all other PIDs have a value of 0, even the VIN is empty

how can i debug the ODB connection, what should i check?

I'm not sure you can: back when I used scantool, the readings would come only when the engine was on and for a very short time afterwards.
