User defined Baud rate : 4800, 9600, 19200, 38400, 57600, 115200, 230400,460800,921600 ,1382400.
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
