Hello
My My arduino nano connects to ELM327 in about 20 seconds. Is there anyway to reduce this time e.g knowing the connection protocol name and calling the initialize function. Thankx.
I am getting following msgs.

@MFAISALREHMAN Are you connecting via Bluetooth or a direct serial connection? If it is BT, you might find it establishes a connection faster if you connect with the device address instead of by name.
