Technical specifications of the HC-05 module

The HC-05 is a Bluetooth module (SMD) that uses the BlueCore4 CSR chipsets. It has 7 I / O ports, 8 Mbit of Flash memory for software storage and two modes of operation: through AT commands and in transparent mode.
In transparent mode, it can be configured as a Master, Slave or Loopback, and can connect to other devices that support the SPP protocol.
In the AT command mode, the user can configure the module and send commands.
By checking the logic level of the PIO11 pin, the user can activate the working mode between AT and transparent command.
