Various systems and methods for using single pairing for multiple technologies are provided herein. A system comprises a transceiver; a communication controller to interface with the transceiver and cause the transceiver to: connect to a remote device using a first protocol, the first protocol including a long term key for use in successive connections between the system and the remote device with the first protocol; and receive, from the remote device, a set of technologies supported by the remote device; and a security manager to: determine a set of common technologies; receive from the remote device, a set of tuples for each technology in the set of common technologies, each tuple comprising an identifier associated with the remote device for each technology and a corresponding technology; and create long term keys for use in later connections with the remote device using a technology from the set of technologies.

Single pairing for multiple technologies

A method and apparatus for authenticating a wireless connection between a first device and a second device. In a first aspect, the first device generates a changing passkey code and converts the passkey code to an audio file that is played through a speaker of the first device as an audible signal. A user hears the audible signal and enters the passkey code into a keyboard of the second device. The second device sends the entered code to the first device for authentication. In a second aspect, the first device generates a passkey code and displays the code on a screen. A user speaks the code aloud to a microphone on the second device. The second device converts the speech into text and then sends the converted speech to the first device for authentication. If the codes of the first or second aspect match, the wireless connection is authenticated.

Bluetooth voice pairing apparatus and method

Various embodiments are described wherein a set of devices are configured to be a logical mesh network. Each device has a logical mesh network address. Further, the set of logical mesh network addresses form a sequence from a first address to a last address, and intermediate addresses having both a preceding and a next address. The devices store forwarding information used to determine how to forward a received logical mesh network packet. Other embodiments are described and claimed.

Techniques and systems for logical mesh networks

Disclosed herein are techniques to age filter information for a wireless network. In particular, a device to remove indications to filter beacons broadcast from another device based on the difference between a time a beacon was last received from the other device is disclosed. The device may be configured to update a filter information element each time a beacon is received from the other device and also to update an indication to filter beacons from the device based on the filter information element.

Broadcast aging for bluetooth low energy

Methods and apparatus for determining device location in crowded indoor environments. A mobile device is configured to determine its location using a Wi-Fi Time of Flight (ToF)-based location scheme. Once the device determines it location, it may broadcast its location to nearby devices using a low energy location sharing mechanism that employs low energy broadcast signals identifying the location of the device. The low energy broadcast signals may be used by other devices having a similar configuration, as well as devices that don't use the ToF-based location scheme to determine their locations using RSSI measurements and multi-lateration and/or have such capabilities disabled. The location of a device may be updated by fusing location data derived from the ToF-based location scheme with location data received from nearby devices that are broadcasting their locations using the low energy location sharing mechanism. The sharing mechanism reduces the number of ToF sessions, while also reducing power consumption by using the lower energy broadcasts to share location data.

Determination of device location in crowded indoor environments

Validation information is communicated in a Bluetooth Low Energy (BLE) connected session. Validation data is generated using said validation information. An advertisement string is broadcast from the BLE device in a connectionless session along with said validation data.

Low energy Bluetooth system with authentication during connectionless advertising and broadcasting

Some demonstrative embodiments include apparatuses, systems and/or methods of Bluetooth communication. For example, an apparatus may include a wireless communication unit to receive at a first Bluetooth device an indication message from a second Bluetooth device, the indication message including a state indication to indicate a non-movement state or a movement state of the second Bluetooth device, the wireless communication unit to transmit to the second Bluetooth device an update message including at least one value to indicate a rate of exchanging messages between the first and second Bluetooth devices, the rate being based on the state indication.
