You must make sure that the application wakes up from power_manage() to configure the pwm. Use for example an app_timer and run the pwm configurations from there. You'll see that if you comment out power_manage in your code it will run as expected.

I'm using the nrfpwm library located at the nordic github so here are the exact lines

#if(USE_WITH_SOFTDEVICE == 1)
 sd_ppi_channel_assign(ch_num, event_ptr, task_ptr);
 sd_ppi_channel_enable_set(1 << ch_num);

Also It's advertising and I'm able to connect to the device, the problem is that I'm unable to alter the state of the LED.

How are you assigning PPI channels for the PWM? Are you using the sd_ calls through the softdevice or are you writing directly to the PPI? If you are enabling the softdevice you must use the softdevice functions to access the ppi channels.

Do you see that the device is advertising or is it hanging in the initialization? I'm just trying to understand where it stops when you enable the softdevice.
