The connection process is built on the standard Bluetooth protocol, which is integrated into the Android operating system kernel. Despite the automation of most processes, the correct execution of the sequence of actions ensures stable communication and high quality of audio transmission.
In this article, we will take a closer look at the connectivity algorithms of different headsets, from budget options to flagship systems with active noise cancellation, and learn not only to perform primary peering, but also to optimize settings for games and music, as well as to eliminate typical failures in the communication module.
Preparation of equipment and activation of the coupling mode
The first step is to put the accessories into detection mode. Many users make the mistake of simply turning on the power, which is not enough for the phone.

Higher-quality formats require more processing power of the processor and communication module, which can slightly increase the power consumption of the smartphone. Multi-device management and dual connectivity The current versions of Android based on Redmi Note support simultaneous connection to two audio devices.
