Enhanced rate physical layer for Bluetooth™ low energy

摘要

A method of communicating data in a Bluetooth™ low energy (BLE) module is provided. The method includes modulating an outbound communication signal into a modulated signal with a particular modulation scheme based on a modulation type, and transmitting the modulated signal to a remote device via a wireless communication connection associated with the modulation type. The method also includes receiving an inbound radio frequency (RF) signal, determining if the inbound RF signal is associated with a modulation type, and demodulating the inbound RF signal with a particular modulation scheme based on the modulation type if the inbound RF signal is determined to be associated with a modulation type. In some aspects, the inbound RF signal and outbound modulated signal have symbol rates of 2 Megasymbols per second. In some implementations, the method includes switching between a legacy BLE system and an enhanced rate BLE system.

1. A method of communicating data in a Bluetooth™ low energy (BLE) module, the method comprising:
determining whether to modulate an outbound communication signal with a first modulation scheme or a second modulation scheme based on an exchange of control information with a remote device over an advertising channel, the second modulation scheme being associated with a symbol rate greater than that of the first modulation scheme, the first modulation scheme being associated with a first Bluetooth low energy mode and the second modulation scheme being associated with a second Bluetooth low energy mode; modulating the outbound communication signal into a modulated signal with the second modulation scheme based on the control information indicating that the remote device is associated with the second modulation scheme; and facilitating transmission of the modulated signal to the remote device via a wireless communication connection associated with the second Bluetooth low energy mode.
