https://devzone.nordicsemi.com/f/nordic-q-a/19195/nrf52832---longest-interval-that-softdevice-will-control-cpuOn the nRF52832, what is the longest period of time that the softdevice will control the CPU while doing things with Bluetooth? This is effectively the interrupt latency time for user level interrupts. I have looked for it, but I haven&#39;t found it.en-USTelligent Community 13Tue, 24 Jan 2017 09:58:52 GMThttps://devzone.nordicsemi.com/thread/74344?ContentTypeID=1Tue, 24 Jan 2017 09:58:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:64300132-d56f-48ab-857a-552f92d9aafaOle Bauck<p>You can find the BLE processor usage pattern for connection as a peripheral <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.sds/dita/softdevices/s130/ble_processor_avail_interrupt_latency/ble_peripheral_connection_performance.html?cp=2_3_0_0_15_2_2_1">here</a>. As it states the longest processing time is in the post-processing which can take <strong>typically 90us</strong>, and <strong>worst case</strong> up to <strong>231us</strong>.</p> <p>See the other sections in the same chapter for more information.</p><div style="clear:both;"></div>
