Abstract: 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.

Abstract translation: 提供了一种在Bluetooth™低能量（BLE）模块中传送数据的方法。 该方法包括：基于调制类型，将出站通信信号调制成具有特定调制方式的调制信号，并通过与调制类型相关联的无线通信连接将调制信号发送到远程设备。 该方法还包括接收入站射频（RF）信号，确定入站RF信号是否与调制类型相关联，并且如果确定了入站RF信号，则基于调制类型来解调具有特定调制方案的入站RF信号 与调制类型相关联。 在一些方面，入站RF信号和出站调制信号的符号速率为每秒2兆符号。 在一些实现中，该方法包括在传统BLE系统和增强速率BLE系统之间进行切换。
