The application of Bluetooth technology has become a part of our life, and Bluetooth low power has been applied in a variety of Bluetooth intelligent products with its advantages of low power and low cost, so what are the characteristics of Bluetooth low power?
- Low power consumption
In terms of appearance and use mode, Bluetooth low power aims to reduce power consumption. In order to reduce power consumption, most Bluetooth low power devices are in hibernation state. When an activity occurs, the device will be woken up and start working, and then enter hibernation state after working. The low power Bluetooth 4.0/4.2/5.0 module developed and produced by Yunliwuli adopts Nordic and other high quality chips, featuring low power consumption, anti-interference, small size, long distance and low cost. , five features of Bluetooth Low Power. - Stability
Security and reliability, Bluetooth Low Power uses the same adaptive frequency hopping (AFH) technology as traditional Bluetooth technology. In order to minimize the cost and power consumption of using AFH, Bluetooth Low power has reduced the number of channels from 79 1 MHZ wide channels of traditional Bluetooth technology to 40 2 MHZ wide channels. - Wireless coexistence
Bluetooth technology uses a 2.4GHz ISM band that requires no authentication license. Because there are too many technologies sharing this radio wave space, wireless performance is compromised by error correction and retransmission caused by interference (such as increased latency and reduced throughput). In demanding applications, interference can be reduced through frequency planning and special antenna design. Because both traditional Bluetooth and Bluetooth Low Power use AFH, which can minimize interference from other radio technologies, Bluetooth transmission has excellent stability and reliability. - Connection range
The modulation of Bluetooth Low power technology is slightly different from traditional Bluetooth technology. This different modulation achieves a connection range of up to 300 meters with a 10-milliwatt dB wireless chipset (Bluetooth Low Max power). - Ease of use and integration
Bluetooth Low power is typically based on a single master device connected to multiple slave devices. The master device controls the communication frequency of the slave device, and the slave device can only communicate according to the master’s requirements. Compared to traditional Bluetooth, Bluetooth Low Power technology adds a new feature is the “broadcast” function. With this feature, the slave device can tell it that it needs to send data (broadcast messages also include activity or measurements) to the master device.
