MATLAB2023a not connected with LEGO EV3 on WiFi.

Telnet_IO.m include in Add-On Toolbox for LEGO EV3 MindStorm.

Error in Telnet_IO.m, line 25

this.Socket = lfsocket.ClientSocket(this.Hostname, this.Port);

It might potentially be defined by idelink

I am having trouble figuring out what product idelink corresponds to.

I also determined the idelink affiliation. I could not find idelink components in MATLAB 2023a. Is it possible to transfer idelink components from previous versions of matlab?

Hi @Victor,

I was encountering a similar issue with the ‘LEGO MINDSTORMS EV3’ support package. Updating the support package through the link mentioned below had solved the issue:

Hope this helps!
