Bluetooth
Bluetooth is a wireless technology standard for exchanging data over short distances using radio waves in the 2.4 GHz ISM band. It enables communication between devices such as smartphones, computers, headphones, and IoT gadgets without cables. The technology supports various profiles for specific applications like audio streaming, file transfer, and device control.
Developers should learn Bluetooth for building applications that require wireless connectivity between devices, such as IoT projects, audio streaming apps, or health monitoring systems. It's essential for mobile and embedded development where peripherals like headsets, speakers, or sensors need to connect seamlessly. Use cases include creating apps for smart home devices, wearables, or automotive systems that rely on Bluetooth communication.
