Hello, I'm getting this 'unpack requires a buffer of 6 bytes' error while running under Windows for 2.71 Firmware with 3.0 Board Version.

Error;

Thank you for sharing your work and library.

Thanks for reporting this error. It should be a duplicate of #26. I have reproduced this error once. Do you get this error consistently? Which gimbal are you using?

Please uncomment line 54 of serial_example.py. I expect a confirmation command after sending a message, but I guess you received a different command that isn't handled properly yet by the library.
