NRF5340 system - I see glitches on sensitive analog every 30msec - seem correlated with Bluetooth. Does anything happen regularly?https://devzone.nordicsemi.com/f/nordic-q-a/119807/nrf5340-system---i-see-glitches-on-sensitive-analog-every-30msec---seem-correlated-with-bluetooth-does-anything-happen-regularlyWorking on a wearable health sensor using NRF5340. Hard to be certain of correlation, but glitches of varying magnitudes appear on my sensitive analog signals (as captured by my ADC) only on exact multiples of 30ms - larger glitches are mostly on multiplesen-USTelligent Community 13Thu, 13 Mar 2025 21:35:35 GMTRE: NRF5340 system - I see glitches on sensitive analog every 30msec - seem correlated with Bluetooth.

It is possible that 30ms is the connection interval for the connection to the phone. You can learn more about the connection interval in&nbsp;<a href="https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/lessons/lesson-3-bluetooth-le-connections/">Lesson 3 of the Bluetooth Low Energy Fundamentals DevAcademy course.</a></p> <p>Exercise 2 in that lesson has an example of how to print out the connection parameters for the connection, so that might help track what the interval really is.</p><div style="clear:both;"></div>
