[ale] bluetooth music receiver always trying to pair?

[James Sumners]

I'd call that a design flaw with the device. Reading the so called
manual[1], it's just as you say. If the receiver isn't currently
connected to a within rage device, then it is waiting for one to
connect. The only thing that prevents a stranger from walking with in
range (33 feet according to the manual) is the PIN required to do the
pairing; but that PIN is the most easily guessed 0000. I'd say look
for a better product. However, the only one I'm finding with some
quick searching is a seemingly discontinued Logitech[2] (it requires a
button to be pushed to initiate an initial pairing). And it doesn't
have an optical out like the one you have :-/

I have some amplified speakers in my house that I wanted to send audio to from my Android tablet, so I could listen to pandora, or podcasts, etc. I searched around town and found the Rocketfish Bluetooth Music Receiver, RF-BTR212, at Best Buy. Functionally, it does what I want, but has a design anomaly that I'm concerned about. Once paired, I can send audio from my tablet to my amplified speakers, just like I wanted. The receiver connects to the speakers I already had, and the tablet pairs with the receiver wirelessly.

I go to the tablet and select search for devices to pair with. I see Music Receiver. I select it, and they pair up. All well and good. However, when I leave the area with the tablet, or turn off its bluetooth, the receiver goes back into hunting mode and blinking again. It has no power switch, so the only way I can stop it is to unplug it.

Can someone explain the pairing process to me and tell me if this could occur? Also, I'm having trouble disconnecting the device and returning the sound to my speakers or headphone jack. Since the receiver is always trying to pair up, if I turn off bluetooth and play audio through the internal speakers, as soon as I turn bluetooth back on, the audio goes back to the speakers hooked to this receiver, and not on the internal speakers. If I leave bluetooth turned off all the time, I cannot use my bluetooth keyboard.
