2、 Use Instructions
Wireless Module consists of master and slave, one master device and one or
more slave devices supporting the use of. When the Wireless Module hardware
circuit is connected correctly and power up, Master and slave devices will
automatically establish a connection and identification with the memory of the
other party equipment, after the user's device using a serial cable using the
Wireless Module.
RS232 Default is to use 2-wire (UART_TX, UART_RX), baud rate 9600,
stop bits, no parity, and no flow control.
Bluetooth default PIN: 1234

6、 AT Instruction Set
z Configuration parameters use the baud rate of 9600, stop bits, no parity.
Serial port configuration parameters are valid only in the work mode.
z Only when the work from the device in the configuration mode, only
allowed executing the parameter setting command. Parameters are modified,
you should restart the device, so that the parameter settings to take effect.
z All instruction data in ASCII format to send to return.
z Carriage return, line feed (\ r \ n), two bytes (ASCII code 0x0D, 0x0A) as
the end of the sign, otherwise the command is not recognized.
z Each command must be outside of the parameters in the following table "<
>" brackets for easy reading and joined without actual instruction "< >".
