Hi Sebastian, Robert,

Sebastian, thanks for pointing out the existing issue.
Robert, would you please comment on that issue stating the needs of your application so we can evaluate how best to fix this and we can also include you in upcoming Pull Request reviews so you can make sure we've addressed it in a way compatible with your requirements?

Andrzej, Vinayak: We should revisit this as soon as possible. Is DTS an option here? I assume not since this is an nRF-specific hardware resource.

Carles

In my application I was try to use 6 PPI channels. And I discovered that
almost all channels is used by BLE stack.
NRF52 chip have dedicated PPI [20:31] channels for radio. Why this
challens was not used by BLE stack.
Is three any posibilities to change this?

Thanks in advance!

Br,
Robert
