Bluetooth 5.3

— the Bluetooth v 5.3 wireless protocol was introduced at the dawn of 2022. Among the innovations, it accelerated the process of establishing the communication channel between the controller and the device, implemented the feature of quickly switching between the state of operation in a small duty cycle and high-speed mode, improved the throughput and stability of the connection by reducing the susceptibility to interference. In case of unexpected interference in the Low Energy mode of operation, the procedure for selecting a communication channel for switching is now accelerated. There are no fundamental innovations in protocol 5.3, but a number of qualitative improvements are seen in it.
