So what happens? Have you tried to debug?

Yes I tested but its not working for me. Even I am not able to connect using MAC ID's.

I don't know why but I am getting connected only using advertising UUID's.

Looks like it should. Have you tested?

Hello Peter,

I enables the static bool is_connect_per_addr = true; and I also modified below code:

if (is_connect_per_addr)
        {
            if (find_peer_addr(&p_gap_evt->params.adv_report, &m_target_periph_addr1))
            {
                NRF_LOG_INFO("Address match send connect_request to peripheral1.");
	    printf("\n\rAddress match send connect_request to peripheral1.\n\r");
                do_connect = true;
            }

        if (find_peer_addr(&p_gap_evt->params.adv_report, &m_target_periph_addr2))
            {
                NRF_LOG_INFO("Address match send connect_request peripheral2.");
	    printf("\n\rAddress match send connect_request to peripheral2.\n\r");
                do_connect = true;
            }

	  if (find_peer_addr(&p_gap_evt->params.adv_report, &m_target_periph_addr3))
            {
                NRF_LOG_INFO("Address match send connect_request peripheral2.");
	    printf("\n\rAddress match send connect_request to peripheral2.\n\r");
                do_connect = true;
            }

        }

Will it work?

Why shouldn't it work?

Then you will have to modify the example to use something else than the service UUID. Could be the device name, the address, some manufacturer specific data. It is up to you.

Hello Peter, I did the below modifications

case BLE_BAS_C_EVT_BATT_READ_RESP:
            NRF_LOG_INFO("Battery Level Read as %d %%.", p_bas_c_evt->params.battery_level);
	    if(p_bas_c_evt->params.battery_level < 40 )
	    {
		err_code = sd_ble_gap_disconnect(m_conn_handle, BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION);
		APP_ERROR_CHECK(err_code);

		scan_start();
	    }

will it work? Currently HRS example is connecting with the help of service UUID. Then how can I connect to other peripheral?

You disconnect with sd_ble_gap_disconnect(). Then you need to scan with sd_ble_gap_scan_start(), receive an advertisement from this other peripheral, and connect to it with sd_ble_gap_connect().

Hello Peter,

I have one central device running HRS central code and four peripheral devices running HRS peripheral code.

Now my central is connected to one peripheral and that peripheral is sending battery level and HRS readings.

Now I want to disconnect that peripheral if the battery level of that peripheral goes below 20% and connect to another peripheral

Please guide me on how to disconnect from that device and connect to another peripheral.

Best Regards, Hrushi

Could you be a bit more specific on what you need guidance on?
