Well your post has been up longer than most and still no reply.
Allow me to take your forum cherry. The reluctance of replys is probably down to the nature of why you would want to watch ppc1 on ppc2 via bluetooth (taking into account that you have a 10m range)
So could you please answer me this survey, and i will be happy to answer your questions.
1) Are you planning to "watch" others, when they most likely are unaware that you are hiding (less than ten metres away)?
2) Have you got an atractive collegue, who rarely checks under the desk?
3) Are you planning to watch the public enter pin numbers into cashpoints, so that you can jump them later?
You get the picture.... I am sure you have a very good reason to want to see something 10m away, or maybe in the next room.... but, validation of the purpose would get you more response.
Please don't take this the wrong way, for all i know you could be my neighbor
