After implement PWM (using pwm example at nRF51_SDK_8.0.0\examples\peripheral) into my BLE based nRF51422 project using SoftDevice S110, it has been working fine; however, I just noticed that calling pstorage_clear and pstorage_update functions from persistent storage manager disrupts PWM operation -- generated incorrect output. Has anyone seen this issue? What's the work around? Thanks.
