https://devzone.nordicsemi.com/f/nordic-q-a/44574/advertising-interval-and-the-led-blinking-interval-in-beacon-example-and-ble_app_bpsDear Sir, I am working with SDK --- nRF5_SDK_15.0.0_a53641a softdevice -- s132 nrf52832. I was working with example codes in the SDK folder. I am working the example codes (ble_app_bps and ble_app_beacon) in SDK folder.

It&#39;s just to indicate that the device is advertising, not how fast/slow it does it. The easiest way to verify the actual advertisement&nbsp;interval is probably to scan for the device in the nRF connect app on Android or iOS. The double arrow (&lt;--&gt; x ms) listed below the device name corresponds to the adv. interval. Note that it may not be 100% accurate&nbsp;because the phone may miss an event now and then.&nbsp; &nbsp; &nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/174923?ContentTypeID=1Fri, 08 Mar 2019 04:43:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bef3f211-cb94-4993-8e64-96db6f4c078bGK<p>Hi, I could find out the following.</p> <p>The advetising interval (APP_ADV_INTERVAL)&nbsp; and interval in which advertising LED blinks(ADVERTISING_LED_ON_INTERVAL and ADVERTISING_LED_OFF_INTERVAL )&nbsp; are different. Now my confusion is how to confirm/check&nbsp; that the advertising happens in the new time interval we set?</p><div style="clear:both;"></div>
