I am working with a board that is intended to receive fuel level data from an OBD II port and send the data through a Bluetooth connection to a mobile app. The problem is that the board gets connected to OBD and all commands work except the fuel level. I transmit commands and I get NODATA answer Meaning that the car responds, but no data is found to bring it as the answer to the fuel command. Do you have any experience on this?
