Do you also think of Bluetooth as just a “headphone-only channel”? Besides connecting to headphones, car audio, or occasionally to a keyboard or mouse, it seems to have no other use? If you are using Bluetooth this way—then you are really underestimating it. In fact, Bluetooth is far more than just a “sound transmission tool”; … Read more
During the storage of tobacco leaves, the temperature and humidity are easily affected by changes in the environmental temperature and humidity. If there is an imbalance in temperature and humidity, it may lead to moisture absorption or even mold growth in the tobacco leaves. To ensure stability and safety during the storage of tobacco leaves, … Read more
Bluetooth to CAN devices typically integrate a CAN communication interface circuit and a Bluetooth communication module. They continuously monitor the CAN bus and Bluetooth bus, and when data is detected on the CAN bus, it is immediately parsed and converted into a Bluetooth communication format, which is then sent out via the Bluetooth module. Conversely, … Read more
Bluetooth Low Energy (BLE) is a low-power, short-range wireless communication technology introduced with Bluetooth version 4.0. It is now widely used in fields such as the Internet of Things (IoT), smart homes, health monitoring, and wearable devices. Compared to traditional Bluetooth (BR/EDR), BLE significantly reduces power consumption while maintaining a similar communication range, making it … Read more
Introduction In the past, when developing with STM32, communication with mobile phones generally required an additional Wi-Fi module or Bluetooth module, typically connected via serial port to the Bluetooth module. When designing wireless communication solutions, the ESP32 is often chosen, as this Bluetooth + MCU integrated solution is very appealing. However, the ESP32 has its … Read more
