Coexistence of protocol stack: The dual-mode Bluetooth module has two Bluetooth versions built in, running the protocol stacks of classic Bluetooth and BLE respectively. This means that it can switch freely between the two modes and choose the most suitable communication method according to needs.
Classic Bluetooth (BR/EDR): Classic Bluetooth is mainly used for applications that require high data throughput, such as wireless audio streaming. It provides a higher data transmission rate, but with higher power consumption.
Bluetooth Low Energy (BLE): BLE is designed for low power consumption and is suitable for IoT devices that transmit small amounts of data periodically, such as sensors and smart wearable devices. It can greatly extend the battery life of the device.
