After pairing and connecting an Android phone and a Windows computer on the Bluetooth settings page, open the phone’s Bluetooth interface to release the pairing with the computer. At this point, using the computer to initiate a BLE connection to the phone will trigger the SMP encryption process. When attempting data exchange, a key missing message will be reported, and then the PC will disconnect on its own. What Windows API can be used to establish a connection without triggering the SMP encryption process or using other methods to disconnect without reporting a key missing message and allow data exchange to proceed normally?
