Why is my Nexus 4 no longer connecting to my Bose Mini Sound Device?

[AC Question]

Both devices are fully charged and turned on yet my phone searches only to report that there are no devices within range. Worked yesterday and for five months since I bought it.

Welcome to Android Central! Did you try unpairing them (i.e., make the phone forget it completely), then pairing again? Or does it not see the Bose device when trying to re-pair?
