What is Device PR BT 2BE7

When I bring up System Preference and the BlueTooth menu, I see the entry PR BT 2BE7 with a Bluetooth icon next to it. I have no idea what device this is supposed to be. If I click Connect it says Waiting for "PR BT 2BE7" to accept the connection. Sometimes a spinning asterisk or gear is shown on the line which says devices and at others it is not there.

Make sure The code shown on "PR BT 2BE7" matches this one (a six-digit code that is different each time I try it and after a few seconds. the notice vanished and *Sometimes& another line P2050 appears also with a connect button. If I click on Connect, after many seconds (about 10) it Couldn't connect to the d (device ?)
