mesh priority

[inv4]

Hi, Im developing an ac dimmer with zero crossing on mesh, but it flickers at low dimming levels, I even used the scheduler for the ble stack but it didnt help, what would you recommend me to do?

Hi. 

Are you working with BLE Mesh here, or another Mesh protocol?

We have a dimming example in our nRF5 SDK for Mesh. Have you looked at that?

Regards,

I'm working with ble mesh, I think the example is using pwm? And I have to use zero crossing

[Joakim Jakobsen]

The example is using PWM, yes.

You can find the example documentation here:

I can't use PWM because I'm detecting zero crossing which occurs every x microseconds... Soft device is messing with my TIMERS, is there a way to set the mesh and proxy activities to a lower priority than GPIOTE and app_timer?
