I wasn't going to use sleep in a while loop anyway. Someone in a perl group on Facebook suggested, POE. But I was looking at Tk::After then had to stop because something came up. But I thinks that where I'm gonna start. I had a look at POE and it looked like Tk::After was an easier approach!

I'd like to clarify that what I am doing is using hcitool con to check for connected Bluetooth devices and parse out the word handle with its corrisponding number. I run the command and push the output to a file. Then parse the handle number and add it to a button. Depending on how many connected devices there are is how many buttons I want to be displayed on my UI.

The only problem is that if I start the program and only one device is connected, it'll show one device. If I connect another device, the program won't load the button. This is why I want to run a command to dynamically load buttons.
