NREC

CSR8系列Configuration tool中HFP Features-HFP Supported Features-NREC,如果选中的话就意味着disabled了手机上的noise reduction and echo cancellation，不选中的话就enable 手机上的noise reduction and echo cancellation？

CVC文档里有一句“For best interoperability between the phone and headset product, CSR recommends the Bluetooth Headset Profile (HSP) with an implementation of AT commands for turning off the mobile phone’s noise reduction and echo cancellation processing”，如何发送一个AT commands to turn off手机的NREC,是不是不选中Configuration tool中HFP Features-HFP Supported Features-NREC
