This is threaded programs, you can't get a data, using bluetooth has been parked in the socket=serverSocket. The accept (); , the debug view sockets=null, bluetooth connection, can realize the function of sending data, found two days but could not find a solution, everyone a great god genuflect is begged to give directions, thank!

CodePudding user response:

have good people to teach it to me

CodePudding user response:

You two are asynchronous, permission to apply for it

If two are asynchronous, you have to wait until AcceptThread completes to implement the run method, otherwise must be null

CodePudding user response:

You don't have to send data to success

CodePudding user response:

The same problem, has been aceept is nil
