Pymakr 1.1.8 VS Code - Failed to Connect

  • I've recently updated to Pymakr V1.1.8 on VS Code and now I cannot connect to my Lopy 4.0 via the Com Port. The device is available within the Windows Device Manager and I can programme it using Atom but with VS Code I cannot connect. Anyone aware of why this might be occuring?

    I cannot revert back to a previous version of Pymakr and I have unistalled and reinstalled VS Code and the Pymakr extension. I am using V 1.53.0 of VS Code.

  • I just downgraded my VSCode to 1.52.1 (November 2020), forgot to disable auto-upgrades, and it re-upgraded to 1.53.2. Although was the same version as before, now the pymakr plugin is working correctly with my lopy...
    Running on Windows 10, using FTDI usb-serial with W10 usb serial driver....

  • @Matthew-Felgate-0
    thx, confirmed it is working now, but the version is even newer 1.1.10

    Hi everyone, the VS Code issue should be fixed now; Please update extension to Pymakr to v1.1.9.

    Apologies for the inconvenience.

  • @Matthew-Felgate-0 Any update on this issue?

  • Confirmed here too

    • Ubuntu 20.04
    • vscode 1.53.1-1612827767
    • pymakr 1.1.8

    Downgraded my vscode to

    • vscode code=1.52.1-1608136922

    And yet again I see the lovely >>>

    How did I do that?

    # find a suitable version
    apt list -a code
    # downgrade
    sudo aptitude install code=1.52.1-1608136922
    # prevent future automatic updates
    sudo apt-mark hold code

  • I confirm the above and report the following:

    I was working on a TTGO-T8 V1.7 (sorry it's not a pycom board) Esp32 Wroom with Visual Studio Code , Pymakr extension on USB under UBUNTU 20.04.2 , everything was ok until a Visual Studio Code update was installed automatically.
    After that, pymakr console can no more connect to my Esp32 board. It sees it connected to my /dev/ttyUSB0 port but it stucks waiting for connection.

    I reflashed Esp32 firmware to no avail.

    I did then install Visual Studio Code on a Win7 machine and installed nodej and pymakr and explained it to look for a Silicon Labs serial chip. It sees it in the device list but it stucks with a "Failed to connect" error.
    Thanks to that I landed here.

    Environment is the following:
    Win 7 64 bit
    Visua Code Version: 1.53.2 (user setup)

    Esp32 wroom module with esp32spiram-idf3-20210202-v1.14.bin micropython firmware.

    I can connect and have a repl via USB and putty on both platforms , Ubuntu and Win7

    I'm desperate.

    Best Regards

  • Hi, Newbie here. I have just installed Visual Studio Code, and nodejs, and when I try to connect for the first time to my wipy, I also see "Connecting to COM6...","Failed to connect (Error: Port is not open)".

  • Glad I came across this! It's my first time working with Pycom and I thought that I completely messed up. I went through all kinds of firmware updates for the expansion and dev boards, amongst trying other things... only to realise there was a bug in the update!

    Are there any further news regarding this issue?

    I can confirm that with VS Code (1.53.0) and Pymakr 1.18, It does not connect to the COM ports. I downgraded to VSCode 1.52.1 and Pymakr 1.17 but it seems to hang at "Connecting to COMx". Can anyone else confirm this issue? Running on Windows 10.

  • @Matthew-Felgate-0 Any update on this issue?

  • Confirmed here as well. For me, all serial ports show up, but I can't connect to any PyMakr devices on them. We now run our computers with internet access disabled to hopefully avoid all Visual Studio Code instances to update themselves...

    Hi all. We at pycom are looking into this issue.

  • Hi !
    I confirmed, same issue here with VS Code 1.53.0 and Pymakr 1.1.8 on MacOS

  • Confirming I have the same issue on the latest version of VS Code.

    Version: 1.53.0 (user setup)

  • @quentinmsl I can confirm I have the same problem, will try this solution

  • Update :
    I reinstalled VSCode in V 1.52.1 (and disable automatic updates) and it worked with the Pymakr in V 1.1.7

  • The same problem, I see the serialport when I do the Pymakr -> Extra -> List Serial Ports but cannot connect.

    Found 2 serialports
    COM10 (FTDI) (copied to clipboard)
    COM8 (FTDI)
    Connecting to COM10...
    > Failed to connect (Error: Port is not open). Click here to try again.
    Connecting to COM8...
    > Failed to connect (Error: Port is not open). Click here to try again.

    When I go back to version 1.1.7 or older of Pymakr, VS Code does not launch the Pymakr console anymore and when I execute a command it crashes

    The command 'Pymakr> Extra's> List serial ports' resulted in an error (command 'pymakr.extra.getSerial' not found)

  • @Karol-Bieniaszewski I can still see the serialport when I do the Pymakr -> Extra -> List Serial Ports

  • i have the same
    even Pymakr->Extra->List serial ports show:

    Found 0 serialports

    no problem with connecting to serial port by any other software e.g. Arduino IDE -> Com port monitor

    Same problem with Pymakr-> atom version
