error: unpack requires a buffer of 4 bytes

[Martin-By]

Hi, thank you sharing your code!

I own a KickStarter Device and try to run your code and learn about it.

Right now I am using Anaconda 2.6.6 with WIN 11 and installed the phython packages needed.

The Device is connected and blinking.

Running the first script (01_scio_usb.ipynb) I get follwing Error message. Do you have any idea about the possible rootcause?

Best regards,
Martin

Run test on unknown commands

#-----------------------------
device_list = search_scio_usb()
if(len(device_list) != 0):
# Note: No support for multiple Apogee devices. This takes the first one found!
device_address = device_list[0]['address']
print(' - Found device at', device_address)
# Now set up device
scio = scio_usb(device_address) # Create an instance for this device address
await scio.run_test(silent=False)
print('Done...')
Searching for devices:

• Found device at COM3
• Connecting to device
• Testing other commands:

• Disconnecting
