The use of Bluetooth has been integrated into our daily lives, and people's demand for Bluetooth functionality is also increasing. The emergence of low-power Bluetooth chips has met the needs of many users, so what are the advantages? Let's read on together! The definition of low-power Bluetooth, Bluetooth technology is a short distance communication system that connects portable or fixed electronic devices, and is an IEEE standard. Basic Rate (BR) and Low Power (LE) are two forms of Bluetooth wireless technology. Both systems also include connection mechanisms, device discovery, and connection establishment. Low power Bluetooth can also be designed with special ratios, which are lower in cost, power consumption, and complexity compared to BR Bluetooth products. Low power systems can also be used in cases of low duty cycle and low data rate. Devices using these two systems can communicate with each other.

Performance characteristics of low-power Bluetooth

1. Four physical layer speeds: 125Kbps, 500Kbps, 1Mbps, and 2Mbps;

2. Receiving sensitivity: Max6.5dBm;

3. Hardware interface: UART, SPI, 12C, PWM, and 3 ADC channels;

4. CPU main frequency: up to 48MHz, with rich interface resources;

5. Data serial port transparency: GATT/GAP, custom UUID;

6. Functional features: BLE HID/WeChat mini program/iBeacon/Mesh networking protocol, etc;

7. Master slave mode: Master slave 1-to-7 communication can also be scanned and connected by mobile phones for communication.
