- You Reply: I figured out the problem.
I was powering the Netdruino off the USB and the only wires I had coming from the car kit was the RX and TX.
I plugged in the GND to the Netdruino GND and it started working fine. :-[
Right now I'm getting about 12.7 PIDs per second with just constantly rescanning the RPM.
Now to set this up with Bluetooth for my phone - You Reply: I get the welcome message from ELM when I plug it into the car OBD port.
But every time I send it "AT" or "Z" it doesn't do anything.
It doesn't even echo. I've tried it with the \r and \n and neither have done any good.
Also, the device never lights up like it does in the picture. Could my device be defective? - You Reply: is there a command I need to send to the adapter to tell it to use my car's baud rate of 115200 instead of another vehical's baud rate? Or is that detected automatically?
