Why can't the mobile phone connect directly to ble?
First of all, the traditional Bluetooth technology and BLE use different communication protocols. Traditional Bluetooth technology supports higher data transmission rate and wider functions, and is suitable for more complex application scenarios such as audio transmission and file transmission. BLE focuses on low power consumption and short-distance communication, and is suitable for high-power scenarios such as Internet of Things devices and sensors.
Secondly, BLE has low power consumption. Compared with the traditional Bluetooth technology, BLE consumes less power when connecting, which can greatly extend the battery life of the device. This is because BLE adopts more energy-saving communication modes, such as intermittent data transmission and sleep mode, to reduce power consumption.
Finally, the connection mode of BLE is also different from the traditional Bluetooth technology. Traditional Bluetooth technology uses point-to-point connection, that is, one-to-one connection. BLE adopts broadcast-based and central-peripheral connection mode, which can support multiple peripherals to be connected to a central device at the same time.
Generally speaking, mobile phones cannot be directly connected to BLE because they use different Bluetooth technologies and have different power consumption characteristics and connection methods. However, many mobile phones now support dual-mode Bluetooth compatible with traditional Bluetooth and ble, which enables mobile phones to connect various types of Bluetooth devices, including BLE devices.
