Hmm, well that's an intriguing setup. I wonder what the timing looks like with another OBD reader. A wild guess is that the simulator responds very quickly, effectively responding with...

Yeah, so the object only needs tx and rx to be able to set the pullups. The problem is that the arduino ecosystem only specifies the baudrate as [argument](https://reference.arduino.cc/reference/tr/language/functions/communication/serial/begin/) for...

Not all ECU's support all PID's, you can query your ECU to determine what PIDs it supports. See the [supportedPID](https://github.com/iwanders/OBD9141/blob/master/examples/supported_pids/supported_pids.ino) example.

> also the data display is 0x1 0x2 0x3 so on follows by a 1 or a 0. im assuming this states whats available? Yep, the 0 denotes not available,...

That `show current data` section on wikipedia is basically the PID description table, if you look there of `0x20`, you'll see that PID `0x20` has the description `PIDs supported [$21...

> When calling display.println(getCurrentPID(0x10, 2)); (address, byte length) no matter available or not the return value displayed is 1 is there a way to call the actual PID that I'm...

Which frequency of chip? I wonder if you run into https://github.com/iwanders/plainRFM69/pull/13 I never got word back from testing of that, but an overflow in the frequency could affect the results....

Thanks for providing comparison! > I'm not sure I have time to parse all of these registers out I think the difference (ignoring some register that I think don't matter)...

> I have CRC checking turned off and there are no sync words so I think using those features would get rid of some of the mess Without both of...

Hmm, sure looks like that should work... no real reason it's a private function, just never needed to be public before. I haven't used this chip in years, so my...
