Hi,

I am facing flickering issue when nodes in mesh receive association message.Once all nodes are associated then they stop flickering.I am using PIO 9,10.

Is there something internal to csrmesh library which is driving these PIO ?

When the device receives association request, it blinks to indicate association has started.

Once association is complete, it stops blinking.

This is written in the code, you can change it.

Regards.

I never faced such problems.

All devices flicker or only the third device ?

Does the flickering occur at a specific rate or it is random ?

What hardware are you using ?

Regards.

All devices are flcikering.Flicker occur after every 5sec.Once all devices associated then they do not flciker.

We are using On semi led driver which require ON/OFF and PWM from csr1012.

Try the CSRmesh example application code (without any changes) on the same hardware and observe flickering.

I have tested this scenario.I this case flicker will definitely occur because PWM frequency is 1Khz .Our led driver requirement is more than 1kHZ.So we are using Very Fast PWM@16KHZ.

I also noticed that when I run VF_PWM code then bulb do not flicker at any level of brightness.
