Low Energy pairing demonstration (requires an additional Bluetooth
®
Low Energy module)
This menu indicates how to manage a Bluetooth
®
Low Energy pairing content in the ST25DV-I2C tag. By default,
the ST25DV64KC-DISCO board does not feature the Bluetooth
®
Low Energy functionality, and is added using the
ST BlueNRG module.
For this demonstration, the user reads the ST25DV-I2C tag content with a smart phone having the Bluetooth
®
Low Energy OOB support (e.g. Android
™
6.0).
With the MCU, the user:
•
Stores an NDEF message containing the Bluetooth
®
Low Energy Out-Of-Band (OOB)
•
Reads a Bluetooth
®
or Bluetooth
®
Low Energy OOB previously stored in the ST25DV-I2C tag memory.
When the user reads the ST25DV-I2C tag with a smart phone having Bluetooth
®
Low Energy support, the
smart phone automatically asks confirmation and connects to the BlueNRG module present on the demonstration
board. The MAC address provided by the smart phone is displayed on the screen of the demonstration board as
soon as the pairing is completed.
The BlueNRG is configured to act as a human interface device (HID); it is displayed on the smart phone with this
name: HID.
The HID protocol is natively supported by Android
™
6.0 smart phones, and this demonstration allows the user to
control a pointer on the paired phone, by touching the screen of the ST25DV64KC-DISCO board. The screen acts
as a touch-pad, the user button as a select button.
Touch the bottom line of the LCD to exit this demonstration.
The user selects the "Change BLE Address" command to prevent spurious connections from previously paired
smart phones.
This changes the Bluetooth
®
Low Energy module device address, and is seen by smart phones as a different
device (however the device name - HID - is left unchanged).
Note:
Some smart phones require a specific action from the user to enable the HID control (this setting may be located
in the smart phone's Bluetooth
®
menu).
