How does bluetooth work? 🤔 For devices to communicate, they must be in proximity and undergo a pairing process, where they exchange a unique passkey to establish a trusted, secure, and encrypted connection, allowing for data exchange. The technology employs frequency-hopping to switch rapidly between 79 different channels, which combats interference and ensures a reliable connection! #science #physics #technology #stem #engineering #tech #airpods #bluetooth | Learning with Lyrics
