Bluetooth LE, or Bluetooth Low Energy, is a new technology that is separate from traditional Bluetooth. It is designed for low power consumption and has several unique features. Unlike regular Bluetooth, Bluetooth LE hops after a certain number of packets are sent, allowing devices to shut down their radio for extended periods of time while maintaining a connection. Bluetooth LE also allows devices to send unsolicited broadcasts of small chunks of data. The Nordic nRF24L01+ is a device that can perform all these functions. However, there are some limitations, such as the inability to handle certain packet lengths and the lack of support for quick frequency hopping. Despite these limitations, Bluetooth LE is a useful technology for certain applications, such as keyboards and mice.
