There are 2 wireless modes in Bluetooth 4.0: Basic Rate（BR/EDR）and Bluetooth Low Energy（BLE）. Different from BR/EDR (traditional Bluetooth) and Bluetooth 3.0, BLE is used to transfer little data rather than audio and massive data. This is because its low power consuming character. In order to keep consuming low power, it simplified hand-in-hand protocol and shortened awaking time. In short time and little data transportation, it only consumes 10% power of traditional Bluetooth. But if in long time and massive data transportation, its low power consuming character won’t show its advantage.
Jinou low energy Bluetooth module uses TI BLE chipset, which supports Bluetooth 5.0 protocol. It can be used in power consumption sensitive situations, such as commercial medical care, mobile accessories, sports and healthy application. The module supports multiple roles to establish multiple connections simultaneously, namely it can connect other BLE devices and can be found and connected by other BLE devices at the same time.

# 1: This refers to the data transfer rate between two modules, which is related to the connection parameters. The test is done when the connection interval is set to 8. If use different mobile phones and modules to transmit data, the speed may different.
# 2 3 4: This value varies with the connection parameters, and different master devices may have different values, such as using different mobile phone connection module, the power consumption of the module is different.
