Time information profile

Introduction

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

The BLE Time Information Profile is an example profile application implementing BLE Time Service. When the BLE device connected with a compatible iPhone device supporting time service reads the current time, date and day information from the iPhone and displays it on the console. This example application also works with BLE compatible Android devices running Atmel Smart Connect mobile 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 the iPhone, enable Bluetooth in the Settings page. The phone will start to scan for devices. ATMEL-TIP will be appear among the devices scanned.Click on ATMEL-TIP to connect.
    • 7. Once connected, on the client side will request for pairing procedure with iPhone.The console log provides guidance to the user to enter the pass-key on iPhone.
    • 8. On iPhone side, a pop-up screen prompting the user to enter the pass-key. Enter ‘123456’ in the text box and click on ‘Pair’.
    • 9. Press the SW0 button on supported platform to read the internally supported characteristic values from iPhone.

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 Services- The Time profile enables the device to get the date, time, time zone, and DST information and control the functions related to time. TIME-INFO PROFILE supports three services:
    • Current Time service -
      • This service is used to obtain the date and time, and related information such as time zone as exposed by the Current Time service in the peer device.
    • Next DST Change service -
      • This service is used to obtain Information of when next change of daylight savings time (DST) will occur can be retrieved from the peer exposed by the Next DST Change service.
    • Reference Time Update service -
      • This service enables the device to request updating the time on the peer device as exposed by the Reference Time Update service.
  • Platform Services -
    • Interface Settings -
      • Connect ATBTLC1000 XPRO to SAML21-XPRO-B -> EXT1
      • Connect ATBTLC1000 XPRO to SAMD21-XPRO -> EXT1
