What Is Bluetooth Low Energy

Bluetooth А, full name is Bluetooth Низкая энергия, colloquially Бле, it’s a wireless personal area network technology designed and marketed by the Bluetooth Сказать aimed at novel applications in the healthcare, fitness, маяки, безопасность, and home entertainment industries, и т. д.. It is independent of Bluetooth BR/EDR and has no compatibility, but BR/EDR and LE can coexist.

Until now Бле has developed Бле 5.2, Бле 5.1, Бле 5.0, Бле 4.2, Бле 4.0 Bluetooth LE version, compared to Classic Bluetooth, Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication rang, the data rate normally lower than Classic Bluetooth, the iOS device only supports Bluetooth LE for data transmission by default, and normally, the data rate is about 4KB/s for BLE, but Pareasycom company has the Bluetooth модуль supports BLE data rate up to 75KB/s. The speed is many times faster than ordinary BLE.

The FSC-BT836B and FSC-BT826B Bluetooth 5.0 dual mode modules are highly recommended for applications that require high data rate, these two models simultaneously support Classic Bluetooth and Bluetooth LE.

Bluetooth LE mainly includes two protocols: ГАТТ и Сказать Сетка. For ГАТТ profile, it divided into ГАТТ central and peripheral (also known as GATT client and server).

Bluetooth LE has some profiles for sporting and fitness accessories include:

  • BCS (Body Composition Service)
  • CSCP (Cycling Speed and Cadence Profile) for sensors attached to a bicycle or exercise bike to measure cadence and wheel speed.
  • CPP (Cycling Power Profile)
  • HRP (Heart Rate Profile) for devices which measure heart rate
  • LNP (Location and Navigation Profile)
  • RSCP (Running Speed and Cadence Profile)
  • WSP (Weight Scale Profile)

Other profiles:

  • IPSP (Internet Protocol Support Profile)
  • ESP (Environmental Sensing Profile)
  • UDS (User Data Service)
  • Хог (HID over GATT Profile) allowing Bluetooth LE-enabled Wireless mice, keyboards and other devices offering long-lasting battery life.
