Manual firmware update of MindConnect Nano

To prepare your MindConnect Nano for V3 please follow the next two steps:

  • Set MindConnect to factory settings
  • Load new firmware on your MindConnect Nano

Set MindConnect to factory settings


This procedure is only necessary for boxes that were already connected to V2 (SAP). V1 cannot be upgraded.

  1. Set the MindConnect back to factory settings.
  2. Create a “ConBox_Commands.json” file with your favorite code editor.

            "Cmd": "DoFactoryReset",
            "DeviceID": "MindConnectID"


MindConnectID has to be replaced with the serial number of the device.

  1. Copy the extracted/unzipped fw.tar file to a USB stick (fat32 formatted).
  2. Plug the USB stick in the MindConnect hardware.
    • The MindConnect will be restarted automatically.
