setConnectionInterval

[kompost]

The method setConnectionInterval(min, max), seems not to work? I have tried with numerous intervals, but none of them are being set. I understand that the device acts as a slave, and the master always decides on connection parameters.

But if I inspect the devices PPCP (Peripheral Preffered Connection Parameters) they are set as 0xFF-FF, in other words not been set. Why is that?

I need a connection interval of 15ms - 30ms window, sending lots of data frequently is required for my application.
