R&Q:

• Three advantages of BLE low energy Bluetooth module?

BLE Bluetooth module has lower power consumption and long power supply time

Bluetooth low energy is used in smart products, and it can work for a year or two or even longer with a small battery. Compared with other wireless technologies and the power consumption of classic Bluetooth, this is the communication technology that smart products are willing and desirable. .

Low energy Bluetooth module connection speed is fast

The Bluetooth low energy module technology uses a very fast connection method, and the connection time interval is variable. This interval can be set from a few milliseconds to a few seconds according to the specific application. It can be connected to the smart phone almost instantly, which greatly reduces the waiting time .

Low energy Bluetooth module uses unlicensed frequency band

Because Bluetooth low energy technology is a free electromagnetic frequency band, the 2.4GHz frequency band that Bluetooth low energy runs on is exactly an electromagnetic frequency band that is completely free. Others such as WiFi and induction cookers use the 2.4GHz frequency band. Because this frequency band does not need to pay special authorization fees to the radio management department.
