Introduction to Bluetooth
Bluetooth is a wireless communications technology that allows devices to communicate with each other without the need for a central device like a router or access point. It features a low energy mode, making it ideal for devices that require minimal power consumption, such as the micro:bit.
Key Features:
- Low Energy Consumption: Bluetooth's low energy feature allows devices to operate without draining their batteries quickly.
- Profiles: Each Bluetooth device has a profile that defines how it communicates with other devices, detailing its features and capabilities.
- Attribute Table: Bluetooth devices maintain an Attribute Table that can be accessed by connected devices, facilitating data exchange.
Use Cases:
- Microcontrollers: Used in educational tools like the micro:bit for programming and interactive projects.
- Wearable Devices: Commonly found in fitness trackers and smartwatches for data transmission.
- Smart Home Devices: Enables communication between smart appliances and mobile devices for home automation.
