Connectivity HC05 pin

Tx Rx 3.3V GND PIO8 PIO9 PIO11

PIO8 is used to control LED indicating the status. It will blink after power on.

PIO9 is used to control LED indicating paring. It will be steady on when paring is successful.

PIO11 is used to set this two mode: AT command mode (if the pin is connect to 3.3V) or Automatic binding transparent data mode (if the pin is connect to GND). The AT command mode is used to configure some characteristics of the device (for example the Master, Slave or Loopback modes).
