When a peripheral is quickly power cycled, it restarts advertising long before the central has noticed that the previous connectionen-USTelligent Community 13Thu, 21 Dec 2023 17:52:50 GMThttps://devzone.nordicsemi.com/thread/461494?ContentTypeID=1Thu, 21 Dec 2023 17:52:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5a9865cd-813c-45c2-9f6f-382db999ed8cpderocco<p>In other words, no, there is no way for the application to tell the softdevice to kill off a connection immediately. You should consider adding this functionality for this particular situation, or better, the ability to update an existing connection and continue to use the same handle when this happens.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/461208?ContentTypeID=1Wed, 20 Dec 2023 07:02:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:84a6a707-4892-4759-8b0e-6a2aa1495916AlexMiner<p>Effectively managing scenarios involving rapid power-cycling of peripherals while avoiding duplicate connections poses a considerable challenge.</p> <p><span>Adjusting the connection parameters, specifically minimizing the connection interval and connection timeout, can significantly reduce the time it takes for the central device to recognize a disconnection and initiate reconnection.</span></p> <p>Set a shorter connection supervision timeout, defining the duration within which two devices must communicate.
