Description of pin function

• DISC pin: used to actively disconnect bluetooth connections (default high level, low level disconnect)
• PWRC pin: it is used to wake up the sleep (the default state is sleep). The AT command can only be issued when the pin is grounded
• VCC pin: for the power pin of the module, the power supply voltage ranges from 3.6v to 6V
• GND pin: power ground
• TXD pin: serial output pin
• RXD pin: serial port input pin
