A technique to open a single receiving window to perform scanning and initiating operations in a Bluetooth Low Energy compliant device, instead of using two separate receiving windows to perform the equivalent operations. The combining of the scanning and initiating operations in one receiving window, instead of two separate windows, reduces power consumption and provides for bandwidth efficiency.

Concurrent BLE scanning and initiation for bandwidth efficiency and power saving

Disclosed are various embodiments of Bluetooth low energy (BLE) modules and methods implemented therein. An embodiment of the disclosure can obtain in a BLE module an advertiser packet transmitted by a BLE advertiser. An advertiser cache can be checked to determine whether the advertiser cache in the BLE module contains an entry associated with an advertiser address from the advertiser packet. The BLE module can determine whether a payload value of the advertiser packet has changed relative to a previous advertiser packet associated with the advertiser address. The BLE module can then suppress forwarding of the packet to a host processor and/or on-board processor executing firmware. The BLE module can also suppress sending a scan request packet back to the BLE advertiser.
