peripheral_sc_only

Overview

Similar to the Peripheral sample, except that this application enables the Secure Connections Only mode.

Requirements

  • A board with BLE support

  • nRF Connect APP

Building and Running

compile, burn, and more, see：Quick Start Guide

Running Result

  1. Successfully running will output the following logs

I/bt_smp          [0.078] LE SC enabled
I/bt_hci_core     [0.208] No ID address. App must call settings_load()
I/sc_only         [0.214] Bluetooth initialized
I/bt_hci_core     [0.220] Identity: 28:6D:CE:01:02:03 (public)
I/bt_hci_core     [0.226] HCI: version 4.2 (0x08) revision 0x0709, manufacturer 0x070c
I/bt_hci_core     [0.234] LMP: version 4.2 (0x08) subver 0x0709
I/sc_only         [0.300] Advertising successfully started

  1. Run nRF Connect APP, perform scan . Connect it after and you find SC only peripheral is discovered, proceed with the connection. After a successful connection, when the nRF Connect APP prompts for a pairing request, confirm it. Following confirmation, a dialog box will pop up for entering the pairing code.

  1. The development board receives a connection request from the nRF Connect APP and initiates the pairing process with a security level of BT_SECURITY_L4 .It then prints the pairing code 221727 and outputs the following log:

[I] (9854) sc_only: Connected 45:8B:76:3F:1D:E8 (random)
[I] (15454) sc_only: Passkey for 45:8B:76:3F:1D:E8 (random): 221727

  1. Enter the pairing code in the nRF Connect APP and confirm. The development board indicates a successful pairing and outputs the following log

[I] (31048) sc_only: Pairing Complete
