The state shows the current state of the Bluetooth. It is used to receive data from the microcontroller and transmits it through Bluetooth. This pin is a data receiving the pin in UART communication. Whenever the Bluetooth module will receive data, it transmits data to TM4C123 through Tx pin. Therefore, we should connect a power supply, HC05, and TM4C123 ground pins to each other.Īs discussed earlier, the HC-05 Bluetooth module uses UART communication to transmit data. Ground reference of both TM4C123 and HC-05 should be at the same level. Therefore, we can connect 5 volts power source to this pin, and also other pins can also operate on 5 volts signals such as Tx and Rx signals. But I/O pins can withstand voltage of up to 5 volts. The operating voltage range is 3.3 volts. The details of all pins and their working is given below: The description of all these pins are given in the next section. Its output header contains six pins namely Enable/Key, Vcc, GND, Tx, Rx, state. The following figure shows the pinout diagram of the HC-05 Bluetooth module.

There are many Android applications available in the Google Play store which we can use to send and receive data to/from HC05. Also, we can use it for communication between a microcontroller and PC or Android application.
In short, this module can be used to perform low-cost wireless communication between microcontrollers such as Arduino, TM4C123, Pic Microcontroller, Raspberry Pi, BeagleBone, STM32, and Arduino Mega, etc. If you don’t know about baud rate, you should read this UART communication tutorial: The default baud rate set for HC-05 is 9600.

Its CSR Bluecore 04-External single chip is already configured to communicate with other Bluetooth devices through serial communication. In other words, it uses UART serial communication to transmit and receive data packets through a classic Bluetooth standard. HC-05 is a two-way full-duplex Bluetooth to serial module.
