Are you able to share your code?

If you want I can make the case private, in case you only want to share the code confidentially with Nordic support.

Actually, the error is that it does not restart... Actually, I initialize the PWN with nrfx_pwm_init giving a handler to it.

In this handler function, I check the event NRF_DRV_PWM_EVT_FINISHED or NRF_DRV_PWM_EVT_STOPPED (I tried both and I got them) and I try to restart a sequence using nrf_drv_pwm_simple_playback (or the complexe, result is the same).

Hi Hugues

Can you provide some more info on the errors you see when you try to restart the PWM?

The functions don't return any error code, so I assume you see this error somewhere else?

Are you able to share your code, showing how you use the nrfx_pwm driver?

Best regards

... and if I have Seq1 and Seq2. Is it possible to make Seq1 (1times) Seq2 (4times) Seq1 (1 times) Seq2 (4 times) ... ? From my tests, it does not seems to work.
