Automatically connected without putting the static passkey at the time of pairing with out bonding.

Question

Hello, I am trying connect with the nRF52840 dongle from my android phone using nRF Connect App. The nRF52840 dongle as peripheral and I am using nRF SDK 15.20 and s140_nRF52_6.1.1 device. My objective is The nRF52840 dongle should connect with nRF Connect App after getting the passkey reply from nRF Connect App otherwise it should not connect. I am using static passkey at the time of pairing not bonding. I have taken reference from This document . and I have implemented in ble_app_gls example. But I disn't get what actually I am wanting. After getting the BLE device by scanning whenever I pressed the "connect" in APP it is connected with the nRF Dongle without putting the passkey also the pairing pop-ups is coming but when I click on "pair" on the paring pop-up dongle disconnected. But the dongle should connect with the nRF APP after putting the passkey on the app. This is my full code below /** * Copyright (c) 2014 - 2019, Nordic Semiconductor ASA * * All rights reserved. * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * * 1.

Thank you advanced.
