مشکل در برقراری ارتباط با bluetooth

[nokia2012]

سلام به تمام دوستان
پیشاپیش تولد امام رضا را به همگی تبریک و تهنیت عرض می کنم.
یه برنامه در رابطه با بلوتوث دارم که دستگاه هارو و سرویسها رو سرچ می کنه ولی میخام با سرویسی که انتخاب کردم رابطه داشته باشم با متد getConnectionURL که این کار تو متد senddata انجام میشه ولی هیچ کاری نمی کنه و حتی پیغام امنیتی هم نمیده .
لطفا اگه کسی اطلاعاتی داره منو راهنمایی کنید.

با تشکر فراوان از شما دوستان عزیز
