Bluetooth technology is a wireless communication technology that guarantees reliable reception and information security in close range. It is an open technical specification that enables short-range wireless voice and data communications anywhere in the world. It uses advanced technologies such as Frequency Modulation Spread Spectrum (FHSS), Time Division Multiple Access (TDMA), and Code Division Multiple Access (CDMA).
In the IOT industry, Bluetooth may be the best choice for wireless communication applications. The reason is based on Bluetooth technology, it has a wide audience and has low power consumption, intelligence, and low cost. . The Bluetooth module is a PCBA board with integrated Bluetooth function, which is generally composed of a PCB board, a chip, and peripheral components, and is used to replace the data cable for short-range wireless communication.
Nowadays,it is an era of endless new technologies. With the support of Bluetooth technology in the electronics field, especially traditional electronic products, many traditional electronic products have a second development and transformed into smart products. When all products add Bluetooth module, must process Bluetooth serial port.
Bluetooth technology as a general communication technology, the main function is to replace the transmission of data cables for portable devices and their applications. This article introduces the continuous innovation and progress of Bluetooth wireless technology.
Bluetooth technology is a short-distance communication technology, widely used in our life. In addition to the early Bluetooth headset, Bluetooth mouse, Bluetooth keyboard, etc., Bluetooth technology is now commonplace in the IOT. Not only about that, Bluetooth technology is also really common in the field of automotive networking.
The HY-40R204I is a 2.4 GHz Bluetooth 4.2 module from Shengrun Technology, which uses a high-performance TI CC2640R2F chip. It can be powered directly using a standard 3V coin cell battery or a pair of AAA batteries. In the lowest power shutdown mode, it consumes only 0.15uA and wakes up in a few microseconds.
