I looked here and Discord for help, but can’t find anything useful. I am not very savvy, so don’t know what to do with the post above by zebus. I don’t know anything about python or pip!
Can anyone help out a total noob? I’ve built cases for remote nodes with solar, but can’t get past the firmware update.
Can you give this solution a try? I think your issue and the original poster’s issue both are related to the serial drivers and /dev entries for these devices. If you look at the first line in the original poster’s image you’ll notice the device is listed as a /dev/cu.usbmodem* device. With the proper drivers installed and working it should be listed as a /dev/wchusbserial* device.
Since you’re getting the same error as the original poster it may be the same issue and getting the right serial chipset drivers installed may fix it.
