is it possible to develop software which uses built in laptop bluetooth to receive mouse signals without bluetooth adaptop that mx 1100 mouse has ?
The MX 1100 is not a Bluetooth mouse. The USB receiver is to receive the proprietary wireless signals transmitted by the mouse. As a result, you cannot use your laptop's built-in Bluetooth hardware with that mouse.
If you purchase a Bluetooth mouse (like the Logitech V470 or the Apple Magic Mouse), you can (and should) use your laptop's built-in Bluetooth receiver; if a USB Bluetooth receiver comes with your Bluetooth mouse, you can set it aside and not use it.
