Hi what do you mean by letting scratch link connect to a private network? I installed the scratch link but I am not able to connect it to the lego WeDo 2.0 Maybe this post will be usefull in the future. I let Scratch link to connect to private networks and… it worked! So I guess something changed the firewall settings for Scratch link. The first time I executed it, the computer prompt a message about the firewall blocking the program. I paired the BT device again, it did not work, either. I tried the offline editor, without success, therefore the problem was not there. So this morning I took several steps to figure out what was happening. Yesterday, fingers crossed, I tried the same but it did not work. So I thought it would be a Scratch issue (we work with the online editor) and taught my lesson without Lego WeDo. On Tuesday 22nd all computers refused to connect to WeDo hubs.

I have four computers, all running Windows 10, LE Bluetooth, Scratch link installed and everything worked fine.

Hi! I teach programming and robotics in an afterschool club and I have been working with Scratch 3.0 and Lego WeDo 2.0 since october.
