  1. Now with Bluetooth 5. 1 you can have the pinpoint location of the device with direction. Earlier we can only know how far your smartphone or smartwatch by using signal strength. But now we will know the distance along with direction with the help of Angle of Arrival (AoA) and Angle of Departure (AoD).
  2. It performs more aggressive cache which can enable you to skip the service discovery stage when nothing has changed from the last connection. Which means a connection to other device is much faster and consume less energy as compared to the previous generation.
  3. The randomized advertising channel indexing helps the devices to select channels at random. It reduces the probability of two Bluetooth devices interfere with each other on the same channels. Moreover, it will be very helpful in areas with a lot of Bluetooth devices.
  4. The new Periodic Advertising Sync Transfer (PAST) feature allows another, less constrained device to perform the synchronization procedure and then pass the acquired synchronization details over a point-to-point Bluetooth Low Energy connection to the other, constrained device.

We hope you understand the main features of Bluetooth 5.1 which have eased out some of our smartphone problems. Although Bluetooth 5.1 doesn’t have many new features as compared to the previous version. But it has some impressive improvements in connection stability.
