Hi Emil

That sounds more in line with my own experiments.

Best regards

That is strange. I just tested it, and found it to be just above 40us.
I tested it a bit differently though, by routing the READY event to a GPIO, and measuring the length of the pulse on a scope.

Can you share the code you used to verify this?

No problem, I only wish I had better news ;)

Hi Michael

We haven't characterized the max/min values for these timings unfortunately, so we don't really know.

The main reason for that is that we haven't seen issues with protocols that use this startup delay as a part of the protocol timing (such as the Enhanced Shockburst protocol).

You are not the first to ask though, and while I can't make any promises at this time it is possible that we will do a more accurate characterization in the future.

Best regards
