BLE OBSERVER Example

Introduction

**************************** Introduction *********************************

  • The BLE Observer Application that bring-up Bluetooth Observer Role on supported platforms.
  • Observer Application continuously listens for BLE advertisement data over the air.
  • This example application supports 12 advertisement data types. They are listed below:
  • Incomplete List of 16-bit Service Class UUIDs
  • Complete List of 16-bit Service Class UUIDs
  • Incomplete List of 32-bit Service Class UUIDs
  • Complete List of 32-bit Service Class UUIDs
  • Incomplete List of 128-bit Service Class UUIDs
  • Complete List of 128-bit Service Class UUIDs
  • Shortened Local Name
  • Complete Local Name
  • Appearance
  • Manufacturer Specific Data
  • TX Power
  • Advertisement Interval

Supported Evolution Kit -

  • ATSAML21-XPRO-B + ATBTLC1000 XPRO
  • ATSAMD21-XPRO + ATBTLC1000 XPRO
  • ATSAMG55-XPRO + ATBTLC1000 XPRO
  • ATSAM4S-XPRO + ATBTLC1000 XPRO
  • ATSAMR34-XPRO + ATBTLC1000 XPRO

Running the Demo -

  • 1. Build and flash the binary into supported evaluation board.
  • 2. Open the console using TeraTerm or any serial port monitor.
  • 3. Press the Reset button.
  • 4. Wait for around 10 seconds for the patches to be downloaded device will initialize and start-up.
  • 5. The device is now in advertising mode.
    • 6. The device is now ready to be used as Observer and starts scaning for nearby BLE devices.

Modules

***************************** Modules **************************************

  • BLE Manger -
    • The Event Manager is responsible for handling the following:
      • Generic BLE Event Handling:-
        • BLE Event Manager handles the events triggered by BLE stack and also responsible for invoking all registered callbacks for respective events. BLE Manager handles all GAP related functionality. In addition to that handles multiple connection instances, Pairing, Encryption, Scanning.
      • Handling Multi-role/multi-connection:-
        • BLE Event Manager is responsible for handling multiple connection instances and stores bonding information and Keys to retain the bonded device. BLE Manager is able to identify and remove the device information when pairing/encryption gets failed. In case of multi-role, it handles the state/event handling of both central and peripheral in multiple contexts.
      • Controlling the Advertisement data:-
        • BLE Event Manager is responsible for generating the advertisement and scan response data for BLE profiles/services that are attached with BLE Manager.
