UArm Communication Error / UarmConnect Exception

uArm Serial No.: (the No. at the bottom of each uArm reading “UARM-0725160146”)

Firmware Version: 2.2.1

Operation System: Mac

uArm Controlling Method: Python - pyuarm xx

Hi, I’ve used to have the pyuarm version from master branch. However, with that one I was having issue with uArm behaving strangely. In addition, there was a communication error in output.

pyuarm - ERROR - Communication| ERROR: send b'#515 G0 X107.36 Y193.64 Z83 F5\n', received error from robot: $514 OK V2.2.1

pyuarm - ERROR - Communication| ERROR: send b'#517 G0 X107.36 Y193.64 Z100 F5\n', received error from robot: $516 OK V2.2.1

After, I wrote you and you told me that you have updated pyuarm and to download it from the dev branch. In spite, I’ve red that was unstable I was having the following error when executing the program.

pyuarm - ERROR - UArmConnectException - set_position - 'uArm is not connected-'

Both the versions are not working correctly. Am I doing something wrong? Or there are actually bugs?
