车联网基本概念

技术本质:对外界发出/收取电磁波信号,交换行驶信息。
ST is launching today the BlueNRG-LP, the first Bluetooth Low Energy SoC to support 128 concurrent connections. It is also our first device to receive the Bluetooth Low Energy 5.2 certification. The BlueNRG-LP supports features such as Long Range, 2 Mbps transfers, and advertisement extensions, to name a few. Additionally, it draws from previous architectures to offer the broadest dynamic range ever on an ST Bluetooth chip. To achieve such a level of performance and optimization, our teams focused on the SoC’s radio and the microcontroller. The latter is now a Cortex-M0+ running at 64 MHz and it uses 64 KB of RAM. Comparatively, the BlueNRG-1 and BlueNRG-2 rely on a Cortex-M0 at 32 MHz and 24 KB of RAM. The new device also has a one-time programmable memory area for security purposes.

The outdoor sensor unit(s) for automatic home or building HVAC systems provide outdoor data from one or multiple bearings (North, East, West, South) to a master actuator. This can be one or all of the following data:​

  • Outdoor air quality (OAQ according to the Environmental Protection Agency)​
  • Temperature and relative humidity (degrees, percentage)​​
  • Light/Sun (lux)​​
  • Barometric pressure (mbar)​​
