The short-range wireless communication methods in the automotive field are gradually shifting from proprietary RF technologies to standard protocol communication technologies, including Bluetooth Low Energy (BLE) technology. In digital key applications, mutual authentication between mobile devices and vehicles is performed to complete operations such as entering the vehicle, starting the engine, locking the vehicle, or … Read more
BLE Mesh is designed for networks supporting large-scale node communication. It can support more nodes communicating over longer message transmission distances (relay nodes), lower power consumption IoT nodes (low power nodes), and reliable message transmission (secure encryption). For instance, BLE Mesh nodes can be deployed in scenarios like parking lots, building automation, and indoor supermarkets, … Read more
Currently, there are numerous articles introducing Bluetooth chips in the market, but most of them are quite similar. What kind of performance do Bluetooth chips really have?
