Firmware update fail with strange message if pyserial not installled (Ubuntu 16.04.2 LTS)

  • Hi Guys,

    I have been trying to update the firmware on my LoPy, I was stuck for some time with a stupid issue.
    I want to share that with you.
    If you get a message such as
    "Something failed trying to connect to the device."
    check that pyserial module is installed (sudo pip install pyserial)
    It would be good to add a test to check if python module are installed in the update script.
    I usually use venv to develop that's why I forget to install it.


  • @olivierd Wow, this tip saved a lot of time. The problem still persists in the updater tool as of today.
