Bluetooth Modules
Bluetooth wireless technology has become very popular in communication, and it is one of the fastest growing fields in wireless technology. Nowadays, the bandwidth demands of mobile phones and personal communication are simple and convenient to use. Bluetooth technology manages the wireless part’s communication channel. Bluetooth modules can wirelessly transmit and receive data using two devices. Using the host controller interface, the Bluetooth module can receive and transmit data from a host system (HCI). The UART and USB are the most popular host controller interfaces, and we covered the UART in this article. The Bluetooth module can be integrated using the UART connections, providing the best possible solutions for Bluetooth embedded systems.
The Bluetooth module is a basic circuit set of chips that are integrated with the Bluetooth function and are used in 2.4G wireless communication modules. For the end user, it is a semi-finished product. The final product, which can communicate via Bluetooth, is realised through a process of functional redevelopment and encapsulation based on the module. A Bluetooth low energy module (BLE) is also known as a BLE module because it supports Bluetooth protocol 4.0 or higher.
The Bluetooth module has two operational modes: command-response and auto-connect. When the module is in automatic connection mode, it will automatically transmit the data connected according to the pre-set method; when the module is in command response mode, it can execute AT commands, and the user can send the module various AT commands to set the module’s control parameters or issue control commands. The AT command has no effect when the module is not connected. When you connect the Bluetooth module to the device, it enters data transparent transmission mode (the AT command is the command used to connect and communicate between the terminal device and the PC application). That is referred to as paying attention. AT commands are strings that start with the letter AT and end with a character. It contains the AT command response data. Each command has a return value, whether it is executed successfully or not.) Connect the Bluetooth module to the USB to TTL’s RXD, TXD, GND, and VCC, then turn it on by pressing and holding the small button on it (press and hold the power on to configure the mode, and power on directly is the normal use mode), Allow the module to enter absolute AT mode, retrieve module information, and retrieve data using the Bluetooth test software.
Typically, you can set the baud rate, master and slave, pairing password, module parameters, device name, connection password, and other parameters. If the baud rate is not the same, the codes will be garbled and the information exchange will fail. It can be used as a full-duplex serial port without understanding the complicated Bluetooth protocol. The RX of the Bluetooth module is connected to the TX of the microcontroller, and the TX of the Bluetooth module is connected to the RX of the microcontroller, as well as the VCC and GND pins, with the rest of the pins being ignored.
Advantages of Bluetooth Module
We don’t need to bring the connection cables when we travel with the laptop and other wireless devices.
As a result, it is wireless technology.
Bluetooth is not particularly expensive.
Bluetooth modules are protocol standardized because they can connect to the same Bluetooth as well as different Bluetooth project models.
The Bluetooth module can automatically connect to another Bluetooth device within 30 feet.
Bluetooth devices, in general, have a low energy consumption, as evidenced by mobile phones.
