Abstract: Provided is a method in a device under configuration (DUC) for communicating with a remote device over a wireless local area network. The method comprises transmitting a beacon to a remote device, providing a first security key to the remote device using first security measures, authenticating the remote device using second security measures, receiving encrypted secrets from the remote device, and obtaining network access using the secrets. Also, provided is a method of providing network access information over a wireless network. The method comprises identifying a device under configuration (DUC) from information contained in a beacon transmitted by the DUC, retrieving a public KEY from the DUC, authenticating the DUC using first security measures, encrypting secrets, and transmitting encrypted commands to the DUC.

Abstract: Systems and techniques relating to angle of arrival (AoA) reverse locationing include: transmitting, by a first wireless device to a second wireless device, one or more reverse tracking service discovery messages via a wireless communication link; receiving, at the first wireless device from the second wireless device, one or more response messages associated with the one or more reverse tracking service discovery messages, wherein the one or more response messages comprise (i) information indicating that the second wireless device is enabled for reverse tracking, and (ii) angle of arrival (AoA) information based on AoA calculations performed by the second wireless device; and determining, by the first wireless device, a location of the second wireless device based on the received AoA information.

Abstract: A host assembly of a wireless device enters into a handshaking procedure with firmware of the wireless device to initiate entry into or exit from a host sleep mode. Before such entry or exit, the handshaking procedure may require the host assembly to send an initiation handshake signal to the firmware, and require the firmware to send a confirmation handshake signal back to the host assembly. Entry or exit may be delayed until after the confirmation signal is received. The confirmation signal may vary depending on the handshaking configuration and activation data, and the confirmation signal may vary depending on whether the wireless device is in a power save mode or not.

Abstract translation: 无线设备的主机组件通过无线设备的固件进入握手过程，以启动进入或退出主机睡眠模式。 在进入或退出之前，握手过程可能要求主机组件向固件发送启动握手信号，并要求固件将确认握手信号发送回主机组件。 进入或退出可能会延迟到收到确认信号之后。 确认信号可以根据握手配置和激活数据而变化，并且确认信号可以根据无线设备是否处于省电模式而变化。

Abstract: Methods, systems and computer program products are described for transferring aggregated data packets over an I/O interface from a host to a multiport embedded device. For example, a method includes receiving, by the device from the host, a single write command that (i) specifies two or more ports from among multiple ports of the device, and (ii) includes two or more data packets to be respectively written to the specified ports. The multiple ports of the device are mapped to corresponding locations of memory of the device. The method further includes saving, by the device in response to the single write command, the two or more data packets at two or more memory locations to which the specified ports are mapped. Additionally, the method includes sending, upon saving the data packets, a single notification to the host indicating that the device is ready to receive another write command.

Abstract translation: 描述了用于通过I / O接口从主机传输聚合数据包到多端口嵌入式设备的方法，系统和计算机程序产品。 例如，一种方法包括由主机从设备接收单个写入命令，该命令（i）从设备的多个端口中指定两个或更多个端口，以及（ii）包括要分别写入的两个或更多个数据分组 到指定的端口。 设备的多个端口映射到设备的存储器的相应位置。 该方法还包括响应于单个写入命令，由设备保存指定端口映射到的两个或多个存储器位置处的两个或多个数据分组。 此外，该方法包括在保存数据分组时向主机发送指示该设备准备好接收另一个写入命令的单个通知。
