- Connect the device with Mobile-1/Laptop-1

- Power off the Bluetooth of Mobile-1/Laptop-1

- Connect the device with Mobile-2/Laptop-2

- Now power on the Bluetooth of Mobile-1/Laptop-1

2. Device will be workable with one Mobile/Laptop at a time (it will keep connected to other device)

3. Once the first device function is on pause, then only the 2nd Mobile/Laptop will be workable
