William San Filippo commented on MYNEWT-536:
--------------------------------------------
A fix has been committed. Needs a bit more testing before being considered
resolved, but tested that a supervision timeout will occur if the device goes
away and that no supervision timeout occurs if data packets are being
transferred.
> MBUF exhaustion can cause connection supervision timeout

> If no mbufs are available for reception it is possible that a connection will
> terminate due to a supervision timeout. In the current code, a mbuf needs to
> be available to hand to the LL task in order for the supervision timeout to
> be reset.
