https://devzone.nordicsemi.com/f/nordic-q-a/19065/is-there-some-relations-between-gpio17-and-ble-advertisement-on-nrf51822Hi there: I found a strange phonomenon about consumption betweeen advtisement and gpio17 of 51822. When I start ble adv while setting gpio17 to input disconnected mode with no_pull, the min consumption can be less than 5uA, but when I change gpio17en-USTelligent Community 13Fri, 20 Jan 2017 07:25:03 GMThttps://devzone.nordicsemi.com/thread/73727?ContentTypeID=1Fri, 20 Jan 2017 07:25:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4d9a5f7f-25fb-4ca9-872e-65aa1b2dffcacauzsh<p>No, it didn&#39;t connect to GND.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/73729?ContentTypeID=1Thu, 19 Jan 2017 12:15:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:26c54b65-dad8-47d3-b8cc-d7eb96a96159Ole Bauck<p>Maybe the pin got shorted to ground when soldering the chip?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/73732?ContentTypeID=1Thu, 19 Jan 2017 02:15:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed4518a9-8273-426f-a628-99186db60f0fcauzsh<p>It is an individual case.

On the DK this pin is connected to a button, but this should not matter if the button is not pushed (it will in that case be floating).</p> <p>200uA sounds like the pin is connected to GND. The internal pull-up resistor is typically 13KOhm, see the <a href="http://infocenter.nordicsemi.com/pdf/nRF51822_PS_v3.3.pdf">Product Specification</a>. If Vdd is 3V, then the leakage current (if the pin is connected to GND and internal pull-up is enabled) will be 230uA.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/73730?ContentTypeID=1Wed, 18 Jan 2017 07:46:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7748c86c-ba59-4ff2-8637-2046fc2b91f3Lars Sundell<p>There is nothing special about gpio17 (pO.17). All gpios are equal (with exemption of the ones that have analog connections. Does this happen on several devices, or only one? My first suspec is that the device in question has a production error that is reviled in this particular case. Even thu all devices are thoroughly tested,it is not possible to test everything, so some devices might have errors.</p><div style="clear:both;"></div>
