Extended PIDs OBD UART

Postby dsmith658 » Sun Jun 18, 2017 8:21 am

I got the OBD-II UART working easily enough with the pre-loaded PIDs. There are some PIDs that are above the 0xXXh range. For example some of these PIDs 0x11XXh range (am guessing this is still hex). Any easy way to support these or will I need to dig into the libraries more?

You can request any PIDs but it varies whether they will be responded or whether new code needs to be added for parsing the response.

I have a PID that is 0x11B3. The standard freematics library cannot handle a two byte command. Can you provide some direction?

You could try with obd.sendCommand().
