https://devzone.nordicsemi.com/f/nordic-q-a/41664/power-consumption-ble-centralHi, I’m developing a BLE remote control device (S132 softdevice &amp;&amp; SDK 15.2.0) . It works with NRF52832 programmed as a central BLE (I started from ble_app_blinky (central) example). My problem is the high consumption of the device: While the deviceen-USTelligent Community 13Mon, 17 Dec 2018 15:24:17 GMThttps://devzone.nordicsemi.com/thread/162129?ContentTypeID=1Mon, 17 Dec 2018 15:24:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:166f13ea-4581-4333-9aac-34d57faced66Simonr<p>Hi,</p> <p>Yes these consumptions are high, but expected. You can try increasing the connection interval so that the radio doesn&#39;t use as much time scanning. For example set&nbsp;NRF_BLE_SCAN_MAX_CONNECTION_INTERVAL&nbsp; and NRF_BLE_SCAN_MIN_CONNECTION_INTERVAL to 100(ms) in sdk_config.h. Remember that you have to change the connection intervals for both central and peripherals to make sure that they overlap.</p> <p>You can also try decreasing the scan window (Although this reduces the chance to detect the advertising packet). This is done by decreasing the variable NRF_BLE_SCAN_SCAN_WINDOW in sdk_config.h</p> <p>Best regards,</p> <p>Simon.</p><div style="clear:both;"></div>
