Abstract

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.

First claim

There, having thus described the invention, at least the following is claimed:

1. A method comprising:
obtaining an advertiser packet transmitted by a Bluetooth low energy (BLE) advertiser in a BLE module in a host device;
determining, in the BLE module, whether an advertiser cache in the BLE module contains an entry associated with an advertiser address from the advertiser packet;
comparing, in the BLE module, an error checking field extracted from the advertiser packet with…
