Hi Brian,

Thanks for clarifying.

Ok, fair enough. We are well aware of performance considerations.

What I'm thinking about is having both modes of communication available,
even if the embedded device has just one Controller, as is the case with
the majority of off-the-shelf platforms.

The reason we want/need both BLE/GATT and Mesh on the same node has a
lot to do with provisioning - at the moment we configure our networks
using a mobile app, meaning we need devices to support PB-GATT. This is
because Controllers present in mobile devices do not support Mesh
natively, and we can't assume there is a GATT Proxy nearby, especially
when configuring a new network.

Ack.

FYI, it seems we might be interested in making that happen.
