Hello,

I bought UB400 Nano Bluetooth adaptor for entertainment purpose of listening wireless music by connecting my mobile with conventional speaker system (not having in built bluetooth). I have inserted this bluetooth adaptor using USB pen drive port of my speaker and try to pair both devices but did not succeed. Bluetooth adaptor is working perfectly on with my computer. I think it passing PIN to pair devices which is not case with speakers. Can you please let me inform is there any other way to pair UB400 without PIN with such devices?

Thank you
