Hi,

I try to evaluate ELS61 and I found a problem.

Look at my listing please:

after some time waiting for incoming data I get a message:

The module hangs and dosn't respond any more. This sitation happened several *****, so it's repeatable error. I also found this problem earlier in JAVA application using ATCommand on the same module.

I was looking for on this forum similar topics but I have not found solution. Is it possible only I have such a problem?
