Slow init simulator code about obd9141 HOT 4 CLOSED

Hmm, could be, I thought the 21 was because of the slow 5 baud init here. I thought that was read as 21, but it is a long time since I used the simulator. It's gotten zero attention after I had working hardware and working initialisation code. I wouldn't really use the simulator to help you develop your own slow init to be honest. It's not created for that purpose, it was mostly created such that I could check my own PID reading code, at some point the simulator did behave identical to my car (including the init), but like I said, detecting the 5 baud init may not be 100% reliable.

In the example where I used it here I actually force the initialisation to be true, this allows you to bypass the initialisation and still allows testing hardware (and reading PID values) as if it is connected to a car. The simulator does work well for acting like a car when it comes to reading PID values.

I could not try the code yet, still working on the transceiver but looked again and seems it should be 204 = binary 11001100.

No problem, thanks for the advice, I will use the simulator code it with care. I will post my results once it works.

Thanks very much

Hello @iwanders your code is correct the value is 21 I just tried. For some reason I had bit banging in my head and I could not understand how sending 11001100 could be 21, but your code is just counting the number of times the port changes so yes I get 010101 and it is 21.

Ah, glad you got it figured out @bonadio! Thanks for the update 👍
