I always reported "multiple definition of MychatToInt" because I didn't have the MychatToInt. c file before, and the function definition and implementation were all in MychatToInt. h. Although no error is reported here, an error is reported when you run the function in this library. In the examples of libllcp: Sudo./npp-server "No symbol of MychatToInt" will be reported ". The final solution is to add our own defined function to

[Description] In bt2.1 and later versions, the Bluetooth protocol has added a Simple Pairing method in addition to the traditional PIN code pairing. This new pairing method is simpler and more secure. Currently, most Bluetooth devices on the market support simple pairing. From the user's perspective, the traditional PIN code pairing requires both Bluetooth devices to enter the pair password (if both si
