The difference between ultra-low power Bluetooth chips and traditional Bluetooth chips. What is included in the ultra low power Bluetooth chip? What is a traditional Bluetooth chip?
1、 What is an ultra low power Bluetooth chip? Ultra low power Bluetooth chip (also known as BLE) refers to a module with a protocol of 4.0 or higher, and its most important feature is a Bluetooth chip that saves power and consumes ultra-low resources. Mainly used in consumer electronics, sensing devices, smart homes, personal care and beauty devices, etc. (The above application fields can be developed using the model AC6321A4 chip to complete most product solutions.) Ultra low power Bluetooth chips also have an important feature that does not require too much bandwidth for device connections, such as smart homes (Bluetooth locks, Bluetooth lights), data transmission of sensing devices (blood pressure gauges, temperature sensors) Consumer electronics (electronic cigarettes, remote control toys), etc. This type of application scenario can use low-power Bluetooth modules.

2、 What is a traditional Bluetooth chip?
Generally, it refers to chip modules that can support Bluetooth protocol below 4.0, mainly applied to devices with high data transmission volume, such as music transmission, voice transmission, speakers, and other high transmission applications. Traditional Bluetooth modules are mainly divided into high-speed Bluetooth modules and traditional Bluetooth modules.
In 2004, the market launched traditional Bluetooth chip modules, with the main representative protocol being the 2.1 Bluetooth protocol. Widely used on smartphones;
In 2009, a high-speed Bluetooth module was launched, which increased the data transmission speed to 24Mbps, which is more than 8 times that of traditional Bluetooth chip modules. It is widely used for data transmission in high-definition televisions, video recorders, computer PCs, printers, and other devices.
3、 The difference between ultra-low power Bluetooth chips and traditional Bluetooth chips
The ultra low power Bluetooth chip was developed on top of Nokia's wibree standard; Traditional Bluetooth has three levels of power consumption, namely class1, class2, and class3, which can support data transmission distances of 100m, 10m, and 1m. If the distance exceeds, data cannot be received for mutual transmission; However, ultra low power Bluetooth chips do not have a power level, with a typical transmission rate of 7dbm; The BLE5.0 module supports Bluetooth Mesh technology.
