https://devzone.nordicsemi.com/f/nordic-q-a/14217/how-long-maximum-time-can-a-ble-interrupt-stay-in-its-isrHi, We are implementing a device where we need to use BLE and PWM. For generating PWM we use app_pwm library. To decide on the number of cycles of PWM pulses, we use a separate timer which stops the app_pwm when the desired number of cycles(or perioden-USTelligent Community 13Wed, 01 Jun 2016 05:10:34 GMThttps://devzone.nordicsemi.com/thread/54303?ContentTypeID=1Wed, 01 Jun 2016 05:10:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a5b3d3ce-2567-40e0-a0e9-10278206cf3eRK<p>All that information is in the softdevice spec for the softdevice you are using. That gives maximum and minimum processing times in both of the two priorities which the softdevice uses. It&#39;s a bit table with lots of graphs and contains all the information you&#39;re looking for.</p><div style="clear:both;"></div>
