https://devzone.nordicsemi.com/f/nordic-q-a/64831/difference-between-advertising-in-idle-mode-and-stopping-advertisementHi all, Is there any difference between advertising in IDLE mode and stop advertising using sd_ble_gap_adv_stop(m_advertising.adv_handle)? I wonder if I need to stop the advertising completely to save power even if the chip is not advertising anymoreen-USTelligent Community 13Mon, 17 Aug 2020 08:56:01 GMThttps://devzone.nordicsemi.com/thread/264793?ContentTypeID=1Mon, 17 Aug 2020 08:56:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd86f334-b18e-4649-8b1d-48a7772de766Simonr<p>Hi</p> <p>When in BLE_ADV_EVT_IDLE, the radio is still enabled and will draw some current, but if you put the device to sleep using sleep_mode_enter() or&nbsp;sd_app_evt_wait() you should stop the radio (and other peripherals) to minimize you current consumption as much as possible.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
