    Abstract: A Wi-Fi device includes a controller coupled to a writeable memory implementing a MAC and PHY layer and to a transceiver. Connection data stored in the writeable memory includes Wi-Fi connection parameters including≥1 router MAC level information or a most recently utilized (MRU) channel used, and IP addresses including≥1 of an IP address of the Wi-Fi device, IP address of the MRU router, an IP address of a MRU target server, and an IP address of a network connected device. An accelerated reconnecting to a Wi-Fi network algorithm is implemented by the processor is for starting from being in a network disconnected state, establishing current connection parameters for a current Wi-Fi network connection using the Wi-Fi connection parameters for at least one MAC layer parameter for the MAC layer.

    Abstract: A network device includes a wireless transceiver configured to establish a bi-directional communication channel with a network gateway. The network device also includes a visible light communication (VLC) interface configured to establish a visible light communication channel with a configurator for the network gateway. The network device further includes a controller configured to operate with the configurator to execute out-of-band (OOB) provisioning of the network device for the network gateway, wherein data communicated on the visible light communication channel includes a portion of information related to bootstrap provisioning the network device with the network gateway using the device provisioning protocol (DPP).

    Abstract: In described examples, ownership of a network protocol-based session is distributed across multiple entities. A session is established between a remote entity and a first processing node on a local device, such that the first processing node is the session owner of the session on the local device. During the session, ownership of the session is transferred from the first processing node to a second processing node on the local device, such that the second processing node becomes the session owner of the session on the local device. The session is then operated between the remote entity and the second processing node as the session owner.

    Abstract: A system and method is disclosed that enables a peripheral or slave device to seamlessly transition in and out of sleep state while remaining completely transparent to host software. When the device is in a sleep mode and incoming data is detected, the device begins a wake-up procedure and data is routed to a first, transitional memory. The size of the transitional memory is selected such that it is capable of buffering data received during time required for the system memory to stabilize from wake-up. Once a second, extended memory is stabilized, the data is buffered from the transitional memory to the extended memory. The device resumes normal operation when its processor has initialized and can read data from the extended memory.

    Abstract: In at least one example, a method includes establishing, by a sniffer provisioning server (SPS) of a first wireless device, a trusted relationship between the first wireless device and a sniffer tool using a public key of the sniffer tool. An out-of-band (OOB) key exchange provisions the public key of the sniffer tool to the wireless device. The method further includes obtaining, by the SPS, key material uniquely related to a communication session established between the first wireless device and a second wireless device using a shared password. The key material excludes the shared password and a session key uniquely related to the communication session. The method further includes publishing, by the SPS, the key material over a channel to the sniffer tool based on the trusted relationship. The channel is secured using the public key of the sniffer tool.
