Triggering a device remotely through bluetooth?

Ok, so i was hoping to set off an electric match using two phones and bluetooth. i hooked an NPN transister up so that when low voltage is applied, it triggers the high voltage output which goes to the electric match. sorry if im paraphrasing here, i hope someone out there understands what im meaning to say. anyways, what i want to do is have an app that works through bluetooth to provide the low voltage i need through the usb which hooks into the npn transister. in other words, a phones usb triggers low voltage place on transister which then gives the higher voltage output. and it does so by using bluetooth to keep it remote. so again, bluetooth triggers usb, usb triggers low voltage place, then that place lets the high voltage go through. let me know if i need to clear up anything and im very sorry about the grammar but ive been racking my brain over this and its 4 am where im at, and i got no sleep. therefor-- too tired to correct spelling errors. any help is appreciated, thank you!

You can't do it directly through USB.
If its an Android phone, there are cheap interfaces that CAN do it for you.

But with an RN41 BT module, you don't need the other phone.

Hey thanks for your help! However, I decided to use a walkie talkie instead.
