https://devzone.nordicsemi.com/f/nordic-q-a/14421/power-consumptionI&#39;ve testing a Raytac mdbt40 module and I&#39;m running the ble uart example (sdk 9.0, gcc debug enabled, no gcc optimization) and no external 32khz crystal I can scan and connect to the module with my phone so it&#39;s running fine. But I&#39;m getting 18mAen-USTelligent Community 13Mon, 13 Jun 2016 11:37:57 GMThttps://devzone.nordicsemi.com/thread/55081?ContentTypeID=1Mon, 13 Jun 2016 11:37:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8fe04cb2-c7fd-479e-977a-4b8c0c227ff3energy<p>Your assumption was correct, I changed the config file enabled led pin separatly and found that I have a shortcut to ground on one pin. Verified on the pcb with my ohmeter ... And on the schematics ! Thanks a lot</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/55080?ContentTypeID=1Mon, 13 Jun 2016 11:02:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f79964c3-58bf-4fbc-9e69-e8d5c80ee42aenergy<p>I wanted to troubleshout my consumption problem, so I restarted from a blank pcb without any component except the Raytac module All the GPIOS pins are not connected (floating). I just have a mdbt40 module without optional 32khz crystal connected to 3V3 and SWDIO Debug. I haven&#39;t also not connected any decoupling caps and .... 1uf caps required on AVcc</p> <p>I tried with calling buttons_leds_init with parameter BSP_INIT_NONE but after calling it mcu draws 15mA APP_TIMER_PRESCALER prescaler is set to 0</p> <p>I use NRF_CLOCK_LFCLKSRC_SYNTH_250_PPM for soft device as there is no 32khz crystal</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/55079?ContentTypeID=1Mon, 13 Jun 2016 10:29:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f277f5e1-16c2-4cf2-bd07-080c0b314cd5Anders Strand<p>The BSP will by default set up 4 pins as output and 4 as input. If the output pins are connected to ground through some load, current will flow there. Do you have a custom pcb layout?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/55078?ContentTypeID=1Mon, 13 Jun 2016 09:12:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c788bd9d-c4d4-4adc-bb11-2872f8b678b7energy<p>A Basic multimeter.<br /> But got same result with scope.</p> <p>I have found the problem but have not fixed it yet: If I remove call to buttons_leds_init then consumption is ok (much less than 1mA with softdevice enabled with 4mA peak)</p> <p>If I had the buttons_leds_init in the init.
