Pin definition :
● PIO8 connects with LED cathodea with 470ohm series resistor in between. LED NEGATIVE connects to ground. After powered on, flashing intervals differ in different states.
● PIO9 is used to control LED indicating paring. It will be steady on when paring is successful.
● PIO11, module state switching pin. HIGH response to AT command; LOW or floating regular work status.
● With build-in reset circuit, reset is completed automatically after powered on.

Steps to set to MASTER:
● Set PIO11 HIGH with a 10K resistor in between.
● Power on, module comes into AT Command Response Status
● Open HyperTerminal or other serial tool, set the baud rate 38400, 8 data bits, 1 stop bit, no parity bit, no Flow Control
● Via serial port, send characters "AT + ROLE = 1 r n",if successful, return "OK r n", where r n is carriage return.
● Set PIO11 LOW, re-power, then in Master state, automatically search for slave module and connect.

Package List:
● 1 * Arduino Serial Port Bluetooth Module with 4P DuPont Cable
