RPM meter connected to Bluetooth OBD plug with ELM327. To request RPM you send to the ELM327 "010C" and the reply is: 7E8 04 41 0C 0D 80 . 7E8 = reply to test, 04 = reply with 4 bytes, 41 = reply OK, 0C = PID (command) echo, 0D 80 = 2 bytes of data.
Most of the code is derived from Erel's examples.
