• determining, at the host device and based at least in part on one or more beacons from the accessory device, that the accessory device is proximate to the host device, wherein a beacon of the one or more beacons comprises information indicating an offset between a time at which the beacon of the one or more beacons is transmitted and a time at which the accessory device will begin a page scan;
• in response to determining that the accessory device is proximate to the host device, transmitting, by the host device, a connection request to the accessory device, the connection request comprising information identifying a value of a clock of the host device, wherein the value of the clock of the host device is used for synchronizing a clock of the accessory device with the clock of the host device;
• after transmitting the connection request, receiving an acknowledgement from the accessory device;
• and
• connecting with the accessory device to form the wireless connection.
