NRF51 soft device with App_PWM not working.

[cbidstrup]

I am trying to use the NRF51 soft device with the App_PWM library. I can get both working individually, but when I try to enable both, I can no longer connect to the device via bluetooth. I am basically trying to integrate the ble_app_uart example with the pwm_library example.

The bluetooth functions properly until I call app_pwm_channel_duty_set(), which leads me to believe that there is some shared resource or something that is conflicting.

Hi,

The SoftDevice uses TIMER0, but there is no problem using TIMER1 or TIMER2 for the PWM.

I have attached a SDK 12.2 ble_app_uart project where I have added PWM. The PWM is setup to blink the LED3 on the nRF51-DK with 5Hz.

It turns out it wasn't an issue with the library and soft device at all. The posted example worked fine on a dev kit, but not on our board. For some reason we had some interference that caused the external oscillator not to work. We switched to the internal RC circuit because we don't need precise timing and everything is working again.
