https://devzone.nordicsemi.com/f/nordic-q-a/82200/notification-latencyI built a game controller hardware for windows . I am supposed to have a few millisec. latency on notifications. But the latency seems to be noticeable. I have also tried before communication between an esp32 and nrf52 dk and also between 2 NRF DK,en-USTelligent Community 13Tue, 30 Nov 2021 08:50:22 GMThttps://devzone.nordicsemi.com/thread/341204?ContentTypeID=1Tue, 30 Nov 2021 08:50:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d2855d90-9cf4-464b-8a86-165c485169bbKarl Ylvisaker<p>Hello,<br /><br />That sounds strange - a noticeable delay will require several connection events to pass without the notification being sent.<br />Are you familiar with <a href="https://www.nordicsemi.com/Products/Development-tools/nRF-Sniffer-for-Bluetooth-LE">the nRF Sniffer tool</a>? It would be great if you could capture a sniffer trace of the on-air communication between the two devices when this happens, so that we may see what is actually being sent between them and identify if the delay happens on-air or somewhere in the application.<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>
