Abstract: A host device, such as a laptop or desktop computer, that supports wireless point-to-point connections with a peripheral device, such as a pair of headphones, mouse, etc., is configured with a proximity platform with which services register to execute particular filters or scenarios upon the host device connecting or attempting to connect with a peripheral device. For example, an advertisement packet transmitted from the peripheral device using Bluetooth may be customized with a particular pattern that corresponds to one or more registered patterns from the registered services, thereby causing the proximity platform to perform particular functions. Peripheral devices can thereby customize their products so that a host computer automatically performs a function upon receiving an advertisement from the peripheral device, such as surface a notification on a user interface of the host device or track the peripheral device's location.
