Bluetooth low energy hostless private address resolution

A wireless personal area network enabled host device, comprising:

• a host processor;
• a wireless personal area network controller;
• an interface configured to allow communication between the wireless personal area network controller and the host processor;
• a communication module configured to establish the connection between at least one client device receiving a broadcast of the host processor name, the connection allowing the exchange of a public address and an identity resolution key for each device;
• a power manager configured to control the power state of the host processor;
• a trusted database stored on the memory of wireless personal area network controller configured to store the public addresses and the corresponding identity resolution keys for the at least one client device, the trusted database corresponding to trusted client devices;
• and
• a software module, stored in memory of the wireless personal area network controller, configured to
• receive the private address and the identity resolution key of a trusted client device while the host processor is in a sleep state, and
• obtain a corresponding public address for the trusted device based on the received private address and identity resolution key, wherein the obtained corresponding public address is stored in the trusted database and is used to authenticate the client device.

A non-transitory computer readable storage medium storing instructions to enable private address resolution using a personal wireless network controller when a host processor is in a sleep state, the instructions comprising instructions that cause a processor to:

• establish a connection with at least one client device receiving a broadcast of the host processor name, the connection allowing an exchange of a public address and an identity resolution key for each device;
• generate a trusted database corresponding comprising the public address and the corresponding identity resolution keys for the at least one connect devices, the trusted database corresponding to trusted client devices for a connection between a trusted client device in the trusted database and a host processor;
• store the trusted database in a data store associated with the personal wireless network controller;
• receive, by the personal wireless network controller, a connection request from a trusted client device while the host processor is in the sleep state, the connection request including a resolvable private address and identity resolution key of the trusted client device;
• obtain a corresponding public address for the trusted client device based on the resolvable private address and the identity resolution key received from the connection request and identifying the obtained corresponding public address stored in the trusted database which is used to authenticate the client device;
• and
• wake, in response to connecting device being authenticated, the host processor to connect with the trusted client device.
