Explore Bluetooth Low Energy ( BLE ) Fundamentals in Weekend

Delve into the intricacies of Bluetooth Low Energy (BLE) with this comprehensive course! We'll journey through the various layers of the Bluetooth Low Energy specification, starting with the foundational hardware Radio Layer and progressing all the way to the Application Layer.

Bluetooth Low Energy is rapidly expanding, powering a diverse array of applications – from robust Personal Area Networks (PANs) to sophisticated Smart Automation Networks. This course focuses specifically on Bluetooth Low Energy Personal Area Networks, dissecting key layers including:

• Radio Layer: Understanding the physical transmission of data.
• Link Layer: Mastering reliable communication between devices.
• L2CAP Layer: Exploring logical connections and multiplexing.
• Attribute Protocol: Working with data characteristics and properties.
• General Access Profile (GAP): Implementing device discovery and connection.
• Generic Attribute Protocol (GATT): Defining data structures and services.
• Security Manager: Securing your BLE connections.
• Host Controller Interface (HCI) Layer: Understanding the interface between the host and the BLE hardware.
• Application Layers: Building custom BLE applications.

Beyond theoretical knowledge, this course provides a step-by-step implementation of an Environment Sensing service. You'll learn to:

• Advertising: Broadcast your BLE presence.
• Establish a simple GATT connection.
• Implement a BLE standard profile.
• Define and add characteristics to expose data.
• Utilize read and notify properties for data transfer.
• Read data from a DHT11 sensor (temperature and humidity).
• Update data every 5 seconds.
• Implement notifications to push data to connected devices.
