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.It is used to indicate the module state.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.
