    2.4 Hardware design rules The module will work when only connect with VDD, GND, UART Rx and UART of the module. User can get the Bluetooth connection status by connecting to the STATUS pin (PIN18) of the module. User can get the working status by connecting to the LED pin (PIN17) of the module. User can connect the TRAN pin (PIN5) so that the module can respond to AT commands in the transparent transmission mode.
