4.2 version quick connection
Latest 4.2 Bluetooth version
Bluetooth 4.2 has three important improvements on the basis of 4.0.
The first improvement is called “coexistence” by the Bluetooth technology alliance. If Bluetooth 4.2 and LTE radio signals transmit data at the same time, Bluetooth 4.2 can automatically coordinate the transmission information of both. In theory, other signals can be reduced to Bluetooth. 4.2 interference.
The second improvement is to increase the connection speed and be more intelligent, such as reducing the time between devices to reconnect, which means that if the user goes out of the Bluetooth 4.2 signal range and disconnects the time is not very long, when the user returns again After the signal range is reached, the device will automatically connect and the response time will be shorter than Bluetooth 4.0.
The last improvement is to improve the transmission efficiency. If the user connects a lot of devices, such as connecting multiple wearable devices, the information between them can be sent to the receiving device immediately. In terms of rate transmission, Bluetooth 4.1 is better than Batch data of 4.0 can be transferred at a higher rate
