Abstract
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, related to low power techniques for a BLE device during a scanning state. The BLE device is configured to scan for a preamble of a packet while in a first power mode and detect when a bit of the preamble is received. Upon detecting that the bit of the preamble is received, the BLE device switches from the first power mode to a second power having a higher operating power for the BLE device than the first power mode. The switch in power modes occurs while the preamble is being received or immediately after the preamble is received and before an access address of the packet is received. The BLE device, while in the second power mode, then scans for the access address of the packet.
