A method according to one embodiment includes establishing, by Bluetooth Low Energy (BLE) circuitry of an access control device, a BLE communication connection with a first mobile device while a main microprocessor and a Wi-Fi circuitry of the access control device are in sleep states; waking, by the access control device, the Wi-Fi circuitry of the access control device from the sleep state in response to establishing the BLE communication connection with the mobile device; establishing, by the Wi-Fi circuitry of the access control device, a Wi-Fi communication connection with an access control server in response to waking the Wi-Fi circuitry from the sleep state; and receiving, by the access control device and from the access control server via the Wi-Fi communication connection, access control data for the access control device transmitted from a second mobile device to the access control server.

A method according to one embodiment includes communicating a wireless advertisement that identifies a clock status of a real-time clock of the access control device, wherein the clock status includes a clock status value indicating that the real-time clock has not been set, establishing a wireless communication connection with a computing device in response to the wireless advertisement, transmitting a session random value to the computing device, receiving a clock update token from the computing device, wherein the clock update token is indicative of an authority of the computing device to update the real-time clock of the access control device, authenticating the clock update token based on at least the session random value, and updating the real-time clock based on a received update time in response to successful authentication of the clock update token.

A method of implementing unified mode Bluetooth advertisements according to one embodiment includes receiving, by a mobile device, Bluetooth Low Energy (BLE) advertisement data from an access control device, wherein the BLE advertisement data includes (i) a BLE advertisement that is compliant with a HomeKit Accessory Protocol and (ii) a BLE scan response initiated by a scan request to the BLE advertisement, the BLE scan response including data to pair the mobile device with the access control device using another security protocol different from the HomeKit Accessory Protocol, pairing the mobile device with the access control device via the HomeKit Accessory Protocol and the another security protocol using the BLE advertisement data.
