A Bluetooth module is a hardware module that integrates Bluetooth communication functions and implements various functions and features of Bluetooth technology. Bluetooth modules typically include a radio frequency (RF) chip, Bluetooth protocol stack, antenna, and other supporting circuitry. These modules provide a simplified way for devices to communicate via Bluetooth wireless technology.
Bluetooth modules typically have the following features and functionality:
Bluetooth communication functionality: Bluetooth modules provide Bluetooth communication functionality, enabling devices to communicate wirelessly over short distances and transfer data to and from other Bluetooth devices.
Bluetooth Protocol Stack Support: The Bluetooth module integrates the Bluetooth protocol stack, including the lower physical layer (PHY) and link layer (Link Layer), as well as the higher logical link control layer (L2CAP) and application layer protocols (e.g. RFCOMM, OBEX, etc.). These protocol layers support various Bluetooth features and profiles.
Radio Frequency (RF) Chip and Antenna: A Bluetooth module typically includes an RF chip, which handles the transmission and reception of Bluetooth signals. It also has an antenna for sending and receiving wireless signals.
Profile and feature support: Bluetooth modules support different Bluetooth profiles and features, such as data transmission, audio transmission, and low-power communication. This allows the device to realize different Bluetooth applications as needed.
Bluetooth modules are widely used in a variety of devices and applications, including consumer electronics, smart homes, medical devices, industrial automation, and more. They provide a simplified Bluetooth integration solution that enables devices to easily communicate over Bluetooth and implement a variety of Bluetooth features.
