Host not seen by clients (B&N Nook HD+)

This is a reiteration of the comment I posted on MCPE-550 - Host not seen by clients (HTC Evo 3D):

We've also observed this issue on a B&N Nook HD+.

I just tested three devices (a Sprint Samsung Galaxy III running CyanogenMod 10.1.13RC, an ASUS Transformer Prime TF-201, and the Nook) on a single subnet, and the Nook was the only one that the others couldn't see as a host. All three ran fine as clients.
