RE: Pwm and softdevice on nRF51822

I am using the latest version of nrf51-pwm-library:

After debugging for quite a while and finally got it working by placing pwm initialization AFTER ble_stack_init(); Actually after everything, related to softdevice and ble initialization, just before while loop.

Hmm,

It seems that all init(config) of pwm is carried out after the routine call of ble_stack_init();(or not?) If you are using pwm lib so provided by nrf, which i think you are using, then please shift your pwm initialization steps into one method and call it BEFORE ble_stack_init();

I have carried out the same with 3 led/channels and init before ble_stack_init() so proper timers get occupied first then let softdevice to occupy TIMER0.

Secondly i pass parameters as nrf_pwm_set_value({0-3}, n); //n {0-255}(int) not int32_t. make sure you have set those LED pins as output in led_init(). Do let us know if you have fixed or this helped you or if problem still persist then do provide any other information regarding your code/arrangements please.
