Bluetooth has a new version - Bluetooth 5.2

The new Bluetooth version brings 3 new features in the communication of this protocol: Enhanced Attribute Protocol:

Represents an enhanced version of the Attribute Protocol (ATT). EATT supports concurrent transactions, allows the interleaving of L2CAP packets relating to ATT packets from different applications, and allows the ATT Maximum Transmission Unit (MTU) to be changed during a connection.

LE Power Control:

1. The reduction of overall power consumption by transmitters through dynamic power management conducted between connected devices.

2. Improvements in reliability through the active maintenance of receiver signal strength so that it stays within the optimal range supported by the receiver.

3. Improvements relating to coexistence with other wireless devices that are in the environment and are using the 2.4 GHz frequency range.

LE Isochronous Channels: This feature allows the communication of time-bound data to one or more devices for time-synchronized processing. It can be used over connections or be broadcast to an unlimited number of devices in a connectionless fashion.
