Moto G phone will not work as a MCPE server.
All other devices on our network (LG Android Phone, iPod touch, Kindle Fire Tablet all running 10.5 as well) are able to host and receive connections.
When the Moto G world is active, no other devices are able to see it in the world list.
Adding an external world using it's local IP address and the standard port will not allow a connection to it either.
