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 "<
