Python issues with IPv6 address of Moku:Go

Support & Troubleshooting Moku:Go
6

Thank you for the reply! I should have provided more information in the previous post.

  • I am able to use the Moku:Go using the Moku Windows app over both WiFi and USB (there is no Ethernet capability on this unit).
  • I am only able to use the Moku:Go using Matlab over WiFi only.
  • For Wifi connection, I use the Matlab code line below, and it works with no problem:

m = MokuOscilloscope(‘192.168.73.1’, true);

  • For USB connection, I use the Matlab code lines below, both resulting in a long list of errors:

m = MokuOscilloscope(‘[fe80:0000:0000:0000:7269:79ff:feb9:12be%20]’, true);
or
m = MokuOscilloscope(‘[fe80:0000:0000:0000:7269:79ff:feb9:12be]’, true);

It looks like the issue is with the “urlread2” file, which is a part of the moku-MATLAB add-on.
