Same issue still persists even after adding the above code in pm_evt_handler.

Try adding the event for PM_EVT_CONN_SEC_CONFIG_REQ in your pm_evt_handler(), and add the code I posted.

As mentioned, the default behavior is to reject pairing request from an already bonded peer. From the nRF side, the phone is still bonded, but the phone don't have the bond data anymore.

If you erase the flash, the bond information about the phone stored on the nRF is also deleted. Note that if you reset the device while pressing Button 2, the bond information is also deleted.

Yes i am using SDK version 15 and there is no event of PM_EVT_CONN_SEC_CONFIG_REQ type defined in pm_evt_handler(). And when i have already unpaired the device then why it is not able to pair again. What happens after erase all command.

Hi,

I assume that you are using SDK version 15.0. The default behavior is to reject pairing request from an already bonded peer. You can change this by setting .allow_repairing to true. You need to do this in pm_evt_handler() for the event PM_EVT_CONN_SEC_CONFIG_REQ.

        case PM_EVT_CONN_SEC_CONFIG_REQ:
        {
            //  pairing request from an already bonded peer.
            pm_conn_sec_config_t conn_sec_config = {.allow_repairing = true}; //Now changed from false to true.
            pm_conn_sec_config_reply(p_evt->conn_handle, &conn_sec_config);
        } break;
