Bluetooth technology handles the wireless part of the communication channel; it transmits and receives data wirelessly between these devices. It delivers the received data and receives the data to be transmitted to and from a host system through a host controller interface (HCI). The most popular host controller interface today is either a UART or a USB .Here, I will only focus on the UART interface, it can be easily show how a Bluetooth module can be integrated on to a host system through a UART connection and provide the designer an optimal solution for Bluetooth enabled systems.
The bluetooth module I will use today is HC-05 which is so familiar and cheap. It is easily available in local indian markets. You can go either offline or online. You may find in about ~600 ₹. May be if you search better, you can get as low as 450 ₹. Continue reading
