My phone won't Re-Pair to the Smartphone controlled kit after sitting overnight

Our kits use Bluetooth 4.0 Low Energy connectivity. With this style of connectivity, you have to ensure you fully shut down the application before leaving range of the kit. The control is constantly looking for the signal from the smartphone device once paired and if you walk away without shutting down the application the control box can no longer sense the smartphone device is paired and will Freeze. If this happens the only way to reset the box is by removing power and reconnecting power.
