Looking to see if anyone has run into this issue and how it was resolved. We have a nrf52832 running sdk 15.3 (also tried 17) sd 132 6.0. We are using the pwm module + nrf_drv_pwm to generate a 135 khz frequency using the 16 mhz clock. The frequency is generated fine but we are noticing the frequency changes from 135 khz to 137 khz or 210 khz to 214 khz on a 20 ms or so period. My understanding was the pwm hardware modules were independent of the radio and therefore would not get interrupted when the radio is active. (scanning or connected device). Any thoughts would be helpful?? I am thinking either scan window / interval parameters are affecting this and / or the number of ble devices in the area we are in. It is pretty noisy in terms on ble advertisements.
