Hi everybody. I'm writing a Java code which have to send and receive some data from an elecronic system through wireless. The connection is done with the RN-171. I'm now trying to connect to the RN-171 network and to send and receive some data. Although I can in my java code set up an ObjectOutputStream and send some data to the RN-171 properly, I can't set up an ObjectInputStream and my app launches the following exception:
The code which generates the exception is:

Thank you in advance.
Regards
