@ Fincode,
There is a method in Flash Lite using which you can create a local file. Its called localSharedObject. The logic i think u need to implement is -
1. Everytime you start searching, add the set of Bluetooth neighbours to your localSharedObject.
2. Now, search this list frequently or when u re-open your Bluetooth port and if you detect presence of a known neighbour, play the sound.
As you might know, other than 5800 XpressMusic , all other Flash Lite devices need help from lower level languages like Python or Sc++. Or go for Kuneri- Lite. If you use Kuneri, you need not know any other language
