Ah! That happens when I try to reconfigure my Cardo motorbike intercom. It turns on the Aura (and TV with a banner across the top!!) and tries to pair with it – much to the annoyance of SWMBO.
For various boring reasons the Cardo needs to be paired to different bits of hatdware from time to time – its during the re-pair process that it wakes the Aura up. During normal turn-on and use it has no effect.
The Aura needs to be configured so that one has to initiate the pair process – not just start it whenever it sniffs a headset in pairing mode.
