This solution is relatively expensive to replace several mBot 2.4. I remember that there was the same discussion when version 5 of mBlock was released on Windows. It took several months of reminder on the forum but Makeblock listened to the community and added the functionality.
Currently I have 20 PCs running Windows 20 and 1 running Linux. I would like to upgrade the 20 PCs to Linux but this feature is missing. Updates on Linux are easier. I’m just waiting for Makeblock to develop 2.4G on Linux and the migration will only be a while (not $$$)
