Asynchronous Hc 05 Uart Bluetooth Is Much

The HC-05 Bluetooth is much different in features from all other Bluetooth devices because of its multiple pins and their functions.

It has multiple pins for the different method which makes it unique as compare to others.

The module normally operates at UART serial communication with TX and RX pins at 9600 baud rates.

It offers a two-way communication method and the HC-05 can act as either slave and master.

The Bluetooth module offers only short distance communications due to its limitation but still, most of the devices come with it due to its speed and security.

The limitation of this device is that it doesnt allow to transfer any kind of media.

It gives feedback to the controller about the connectivity of Bluetooth with another device.

It helps to change the device between data mode and command mode using an external signal.

The HIGH logic state will transfer the device in command mode and the LOW logic state will transfer in data mode.

The default device state without any signal will be data mode.

It has an enable pin which allows toggling between command and data mode.

The device uses UART (serial communication) which is easy to interface with any microcontroller or system.

Its range is up to 8 10 meters but it signals lower down with any obstacle in its way.

In wireless headphones and mouse, HC05 is available for wireless communication due to its fast speed.

In IoT instead of WiFi some devices also have Bluetooth for their communication to avoid the flooding on the internet.

The module has two serial input pins, both will interface for data communication.

TX will interface with RX of the controller and RX will interface with TX of the microcontroller.

The data will be transfer to 9600 which is the default one but it is changeable too.

The basic purpose of the key pin is to toggle between the modes.

The default mode, when there wont be any input on the Key input the device will act as data mode.

In data mode, there will be only data transfer from the device.

After applying the HIGH input signal at the key pin, the device is going to enter the Command mode.

After entering in to command mode the default setting of the module is changeable.
