me and group of colleges are working on app that connects to OBD device and displays that data after working on it, but we are facing a problem on understanding what is the data received by the phone if it connects with the device via Bluetooth and its form.
after some research all we could find was that data can be of hexa form but that did not help us to fully understand the process. if someone can kindly help us with some resources or description that would be appreciated.
