What is the difference between BLE and traditional Bluetooth, and what are the advantages and disadvantages of each?

Traditional Bluetooth: refers to the module that supports Bluetooth protocol below 4.0, and is generally used for the transmission of larger amounts of data, such as: voice, music, and other higher amounts of data transmission. Classic Bluetooth module can be subdivided into: traditional Bluetooth and high-speed Bluetooth module. Traditional Bluetooth module was launched in 2004, the main representative is the module that supports Bluetooth 2.1 protocol, which is widely used in the period of smart phone explosion. High-speed Bluetooth module was introduced in 2009, the rate increased to about 24Mbps, the transmission rate is eight times of the classic Bluetooth, can be easily applied to the VCR to TV, PC to PMP, UMPC to the printer between the data transfer.

Bluetooth module

Low-power Bluetooth (BLE Bluetooth): refers to support for the Bluetooth protocol 4.0 or above the module, also known as the BLE module, the most important feature is the reduction of cost and power consumption, can be applied to real-time requirements of the product in the high, for example: the smart home class (Bluetooth locks, Bluetooth lamps), the sensing device data transmission (blood pressure meter, temperature sensor), consumer electronics (electronic cigarettes, remote control toys) and so on.

Low-power Bluetooth and traditional Bluetooth is actually a big difference, low-power Bluetooth is nokia's wibree standard on the development of up. In power consumption, traditional bluetooth has three levels of power consumption, class1, class2, class3 support 100m, 10m, 1m transmission distance; low power bluetooth but there is no power consumption level, the general sending power in 8dbm or so.

At present, the BLE4.2 Bluetooth module SKB369/BLE5.0 Bluetooth module SKB501 has been supplied in batch, and configured with the SKB369 development kit, which can be used to complete the performance test of the Bluetooth module during the Bluetooth program design stage.
