Bluetooth can't find other devices

Hi guys!

I am designing consumer product with Bluetooth function, but my product could find other device via Bluetooth, and it is not discoverable by other device via Bluetooth.

What happened?

How to solve this design problem?

please give me some ideas


Note
Bluetooth interface: UART

first see whether the Bluetooth devices have their discovery mode ON and are they visible to other devices... use bluesoleil software and check this..... if they are getting discovered then you need to check if the module has enough power as per the spec....

Is it properly powered?
Is is getting discovered?
