https://devzone.nordicsemi.com/f/nordic-q-a/2106/problem-with-connection-parameter-update-in-custom-boardHi, Our custom board stops working after updating the connection parameters. We have a nrf51822 chipset custom board with proximity application flashed on it. Device get disconnected after connection parameters updated (reset and advertise again).

But it is working fine until i do power reset, only power reset cause the problem. And enabling the connected j-link also recovers the device to advertise(how?). Anyways we will check for the short as you said. If u got any logic on this issue please inform us.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/8989?ContentTypeID=1Fri, 04 Apr 2014 11:59:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1e0b8f3d-d234-4851-b154-0f85e6344964H&#229;kon Alseth<p>If you measure 140 mA, then you most definitely have a short somewhere (most likely VDD to GND). Double-check your solderings.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/8988?ContentTypeID=1Fri, 04 Apr 2014 11:50:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:be402dfd-0ec0-4d12-88d2-0ac8e816618abalaji<p>No, actually, my expectation is &lt;2mA (power reset should make the device advertise).</p> <p>Sometimes i used to get 140mA, even there is no application flashed on my device.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/8987?ContentTypeID=1Fri, 04 Apr 2014 11:32:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dfee78c8-b98c-4dfc-8d30-3ffd0dee41a6H&#229;kon Alseth<p>140 mA?! Is that your expected current draw?</p> <p>-H</p><div style="clear:both;"></div>
