Motion detection with bluetooth low energy scan

A computing device comprising:

• one or more processors;
• a Bluetooth unit comprising a receiver configured to receive one or more advertisement packets via the Bluetooth unit, wherein the one or more advertisement packets is associated with a respective Bluetooth device;
• an application processing unit configured to determine a location of the computing device;
• and
• a non-transitory computer readable medium having stored thereon program instructions that when executed by the one or more processors cause the computing device to perform functions, the functions comprising:
• determining whether a location of the computing device has changed based on the received one or more advertisement packets, wherein the determining includes comparing a number of the received one or more advertisement packets with a number of the one or more reference advertisement packets;
• and
• in response to determining the computing device has changed location, enabling a location detection function of the application processing unit of the computing device.
