— wireless protocol Bluetooth v5.3 was introduced in early 2022. Of the innovations in it accelerated the process of reconciling the communication channel between the controller and the device, realized the function of quick switching between the state of operation in small operating cycle and high-speed mode, improved bandwidth and connectivity by reducing interference tolerance. In case of unexpected interference in the mode of operation with low power consumption, Low Energy now speeds up the procedure of switching communication channel selection. Protocol 5.3 does not present any fundamental innovations, but number of qualitative improvements are evident.
