Ti:Car access Bluetooth® low energy + CAN satellite module reference design

Ti:Car access Bluetooth® low energy + CAN satellite module reference design
This satellite module reference design is intended for Bluetooth® low energy passive entry passive start (PEPS) and phone as a key / digital key car access systems. The design demonstrates how control area network flexible data rate (CAN-FD) communication capabilities can be implemented with our Bluetooth wireless MCUs for systems that require higher bandwidth in-vehicle networking communications. Further benefits include reduced power consumption in the sleep state, our CAN auto-addressing method for improved manufacturing, connection monitor capabilities for improved Bluetooth localization accuracy and a compact printed-circuit board (PCB) capable of measuring Bluetooth angle of arrival (AoA) and received signal strength index (RSSI).
Ti integrated circuits and reference designs help you design passive entry passive start (PEPS) modules and key fobs that are secure and compact while reducing system power consumption and optimizing RF and vehicle

蓝牙5和Mesh技术为物联网市场带来强而有力的加值作用

蓝牙5和Mesh技术为物联网市场带来强而有力的加值作用

物联网发展到如今，无线技术纷繁复杂，往往会出现在同一区域的不同设备上，这些无线通信设备之间会出现相互干扰的现象。然而，蓝牙5标准可以减少和其他无线通信技术之间存在的干扰，帮助设备在复杂的物联网环境中与其他无线设备并存。

蓝牙5是由蓝牙技术联盟在2016年提出的蓝牙技术标准，蓝牙5在蓝牙4.2核心规范上大幅提升效能，包括「2倍的传输速度」「4倍的传输距离」「8倍的广播数据传输量」等新优势，强化了在物联网方面的新特性,重点提高物联网的功能。

Ti:Adding CAN nodes in Bluetooth® Low Energy PEPS systems

Ti:Adding CAN nodes in Bluetooth® Low Energy PEPS systems
In a passive-entry-passive-start (PEPS) automotive system using Bluetooth® Low Energy technology, drivers enter their car and start the electric motor (or engine, in the case of an internal combustion engine) using a key fob that communicates with the car’s access systems, instead of a key.

Renesas Extends Bluetooth 5.0 Connectivity to RA Family of 32-Bit MCUs with Arm Cortex-M Core

Renesas Extends Bluetooth 5.0 Connectivity to RA Family of 32-Bit MCUs with Arm Cortex-M Core
Enhanced Security and Privacy for Bluetooth 5.0 Low Energy Connections Supported with Flexible Software Package and Comprehensive Arm Ecosystem.

Renesas Electronics Corporation  introduced the first RA microcontroller (MCU) with an integrated Bluetooth® 5.0 Low Energy radio on 07 May 2020. The single-chip RA4W1 MCU includes a 48 MHz, 32-bit Arm® Cortex®-M4 core and Bluetooth 5.0 core delivered in a 56-pin QFN package. Together, the RA4W1 MCU and easy-to-use Flexible Software Package (FSP) enables engineers to immediately begin development with Arm ecosystem software and hardware building blocks that work out-of-the-box with RA MCUs.

The RA4W1 MCU makes it easy for embedded designers to develop safe and secure IoT endpoint devices for Industry 4.0, building automation, metering, healthcare, consumer wearable, and home appliance applications. The MCU is also ideal for developing IoT edge devices for wireless sensor networks, IoT hubs, an add-on to gateways, and an aggregator to IoT cloud applications.
