https://devzone.nordicsemi.com/f/nordic-q-a/22137/unexpected-nrf24le1-reset-when-going-into-sleepmodeHi, when executing the following code in my application. if face chip reset time to time. I&#39;ve investigated code to find the bug origin and then notice that i ve a difference in my hardware design. I use a pullup resistor of 10k on the Reset chip.en-USTelligent Community 13Thu, 18 May 2017 11:30:11 GMThttps://devzone.nordicsemi.com/thread/86995?ContentTypeID=1Thu, 18 May 2017 11:30:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f4fd8248-4af2-4daf-ac1e-dcbfc236ac83Hung Bui<p>I assume you meant you put a pullup resistor of 10k on the reset PIN of the chip ?</p> <p>I don&#39;t see a problem of having 10k pull up on the reset pin. It should not related to the reason your chip resets. There is a pull-up internally, you don&#39;t really need a pull up externally. If you have one, make sure you don&#39;t let a ESD noise , such as hand touching to touch the pin.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/86994?ContentTypeID=1Thu, 18 May 2017 09:40:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:13bf6b46-7c3f-4874-9a9a-0d118398c518robotox<p>is a brownOut hardware bug could have something to do with this ?</p><div style="clear:both;"></div>
