Abstract
Systems and methods are disclosed for listening window adjustments for power savings in BLE (Bluetooth low energy) communications. BLE devices determine time differences between assumed transmission times and actual receive times for packets transmitted by another BLE device. The BLE device then adjusts a listening window using the time differences, for example, to reduce the size of the listening window based upon the time differences. The adjusted listening window is then used by the BLE device to listen for and receive additional packets from the other BLE device.
