FIND ME Example

Introduction

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

  • The FIND-ME Application describes the bring-up of Bluetooth® Find Me Profile and Atmel® ATBTLC1000 setup on supported platforms.
  • The Find Me Profile **(FMP)** is an example application, which would provide smart alert signaling about BTLC100 device. Hence BTLC1000 device can be tracked from BLE compatible Android/iPhone by using Atmel SMART Connect application.

Supported Evolution Kit -

  • ATSAML21-XPRO-B + ATBTLC1000 XPRO
  • ATSAMD21-XPRO + ATBTLC1000 XPRO
  • ATSAMG55-XPRO + ATBTLC1000 XPRO
  • ATSAM4S-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. On a BLE compatible iPhone®/Android phone, enable Bluetooth in the Settings page. Start the Atmel Smart Connect App and scan for devices. ATMEL-FMP will be appear amongst the devices scanned. Click on ATMEL-FMP to connect to supported platform.
  • 7. Once connected, the client side will request for the pairing procedure with the iPhone/Android phone. The console log provides a guidance for the user to enter the pass-key on iPhone/Android phone.
  • 8. Upon completion of connection establishment, User can see the notifications based on the alert level settings .

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.
  • BLE Profile -
    • The Find Me profile defines the behaviour when a button is pressed on a device to cause an immediate alert on a peer device. This can be used to allow users to find devices that have been misplaced.
    • Find Me profile supports two services:
    • Immediate Alert service:
      • The Immediate Alert service is instantiated as a Primary Service. There is only one instance of the Immediate Alert service on a device. There is only one instance of the Alert Level characteristic in an Immediate Alert service. This alert continues until one of following conditions occurs:
      • An implementation specific time out
      • User interaction on this device
      • A new alert level is written
      • The physical link is disconnected
  • BLE Platform Services -
    • Interface Settings -
      • Connect ATBTLC1000 XPRO to SAML21-XPRO-B -> EXT1
