Today I helped one of our members setup a meshcore repeater. FYI, when you set up a repeater, if there is bluetooth on hte hardware it will be disabled. The only way you can get to a repeater to administer it is by USB to your PC or thru a remote admin session via another meshcore radio.

Meshcore has very sharply defined roles.
1)repeater. Only uses 900mhz radio for it's daily functions. Bluetooth disabled.

2)companion. This is the mesh unit you carry around with you. It will either have a keyboard like a black berry or it will bluetooth to your phone so you can type messages.

3)observer. This is a behind the scenes node. It never transmits, it only listens to the radio side of things and copies the headers of packets to a central server for analytics. This allows those websites with the cool laser beams to show the progress of a packet as it transits the network.
