汽车传感器的数目也就几十个到100+个。但有些车辆的总线ID数目高达300+。就是说，ECU传感器本身有多个ID来实施不同功能。ECU在工作状态中可以发出不同ID的数据包。那么当这些传感器汇总在一辆车里让我们分析的时候，面对如此多的数据包，如何反向推断哪些ID属于同一个ECU？

N_AI（Network Address Information），定义了PDU（Network Protocol Data Unit ）的地址信息部分，主要包括N_SA，N_TA，N_TAtype和N_AE。针对题主的问题，N_SA，N_TA是与CAN ID 相关的，N_TAtype也有些间接关系。

ISO 14229-1（UDS）和ISO 15765-3（Diagnostic on CAN）结合起来共同构成了诊断协议UDS on CAN。

Qualcomm Technologies International, Ltd. today continued to demonstrate its vision and leadership in the wireless audio space with the introduction of Qualcomm® aptX™ Lossless audio technology to its already extensive audio portfolio. aptX Lossless is a new capability of the proven aptX Adaptive technology and a new feature of Snapdragon Sound™ Technology that is designed to deliver CD quality 16-bit 44.1kHz lossless audio quality over Bluetooth® wireless technology.  Qualcomm Technologies has taken a systems level approach and optimized a number of core wireless connectivity and audio technologies, including aptX Adaptive, which work together to auto detect and scale-up and are designed to deliver CD lossless audio when a user is listening to a lossless music file and the RF conditions are suitable.

2021年9月27日，由深圳市科学技术协会（以下简称“市科协”）主办、深圳市物联网产业协会承办的“自主创新大讲堂精品项目-UWB与蓝牙AoA高精度定位技术研讨论坛”在深圳东华假日酒店举办。

Murata has launched the world’s smallest ultra-wideband (UWB) module – measuring just 10.5 mm x 8.3 mm x 1.44 mm – that combines elevated levels of accuracy and reliability with low-power to ensure compact and battery-driven IoT devices operate as efficiently and cost-effectively as possible.

Qorvo, a leading provider of innovative RF solutions that connect the world announced the interoperability of its DW3000 family of products with the Apple U1 chip used in iPhone and Apple Watch models and the new Nearby Interaction protocol specification draft unveiled at the 2021 Worldwide Developers Conference. This compatibility will enable developers to easily evaluate new app experiences based on location, distance, and direction relative to a U1-equipped iPhone or Apple Watch. The DW3000 is Qorvo's next-generation ultra-wideband (UWB) chipset family and is ramping into full production in four variants, along with several modules and beta development kits.

Qorvo’s cutting-edge ultra-wideband (UWB) products add key location functionality to existing applications and unleash a completely new class of emerging location-based products and services.

Qorvo’s UWB products are available as ICs or modules (with or without a microcontroller). We also have development kits that allow you to explore the possibilities with ultra-wideband.
