Hung is currently on leave, and I will handle the case in the mean time.

Yes, this is not supported in S132 v7.x.x either.

Hi Hung,

Is this limitation also in the Softdevice S132 V7.x.x?

Hi,

As far as I know the softdevice can handle host side initiate feature exchange from the peer (send LL_FEATURE_RSP to LL_FEATURE_REQ) but we don't proactively send LL_FEATURE_REQ

Hi Hung Bui

Hi kxct,

Our softdevice doesn't support slave-initialized feature exchange that's why it return LL_UNKNOWN_RSP.
