Hi,
I used PPI module and Timer2 to generate a 4Mhz pwm. But I founld when using softdevice(s110 v7.0), the pwm will be broke a while by BLE advertising or connecting event. So I suppose the ble event will influence the PPI module ?
And is there any other method to generate a 4Mhz or 8Mhz clock to driver external device?
