Windows Bluetooth Proximity Program Changes

We are using BtProx ([login to view URL]) as a bluetooth proximity software. We need either an entirely new version (Windows 7, 8, 8.1 & 10) or a modification to the current files (it is open source.) We need the program to be able to adjust the proximity broadcast. Currently this is approximately 30M. We need to be able to adjust the distance down to as little as 1M or as high as 30M. The other thing that we are requiring for this project is the use of multiple bluetooth devices. Currently, you are allowed to use 1 device, once that device leaves the proximity then the computer enters \"sleep\" mode. We would like to be able to add multiple devices (i.e., mobile phones) and if any of those devices are within range (as set within the broadcast perimeters) the computer WILL NOT enter into \"sleep\" mode and will Unlock if already in sleep mode.
