Error while retrieving the device session

[Gillani0]

Hi,

I can send the Data Push join message and receive and parse its response correctly with correct mic. However, when it tries to save the session I get the following error:

ERROR - can't pickle memoryview objects

This is during self.save() operation.

Would you please show the whole error message or locate the exception position in code? I didn't encounter such an error. This may cost by a bug. I use memoryview in some process to save processing time, but when it comes to pickle (actually it shouldn't appear in pickle process), the memoryview object should be casted into bytes to be pickled.

The bug has been fixed.

Thanks @houluy it seems to be fixed.

However, I've found other issues in your documentations and Join algorithm. Do you mind if I send a pull request? Cheers
