Hi Daniel,

There are a few different modes that the Bluefuit LE friend can be operated in but it does have two-way communications.

They are covered pretty well in Adafruits FAQ, for example, this device operates in peripheral mode, so it cannot initiate communications, only advertise it’s presense and wait for a central device to initiate a connection request.
