https://devzone.nordicsemi.com/f/nordic-q-a/52114/high-power-consumption-bleHi everyone, I have an issue with power consuption. I work with the SDK15.2.0 and the SoftDevice S140 on a custom board. I launch the ble_app_pwr_profiling example on the board, I go straight on sd_app_evt_waitt(), and measure the current consumptionen-USTelligent Community 13Wed, 25 Sep 2019 13:09:58 GMThttps://devzone.nordicsemi.com/thread/211841?ContentTypeID=1Wed, 25 Sep 2019 13:09:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2eb16a67-a4d9-4647-98ed-0472eb999bfcEtienne<p>Hi, thank you for your response.</p> <p>Sorry for the delay.

The default advertising parameters in the example are:</p> <pre>#define CONNECTABLE_ADV_INTERVAL&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; MSEC_TO_UNITS(20, UNIT_0_625_MS) #define APP_CFG_ADV_DATA_LEN&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 31</pre> <p>With an advertising interval of 20ms and a payload of 31 bytes the expected average current is 564µA @3V with DCDC enabled: <a href="https://devzone.nordicsemi.com/nordic/power">https://devzone.nordicsemi.com/nordic/power</a></p><div style="clear:both;"></div>
