I have two mBots, one with Bluetooth and one with the 2.4GHz USB dongle. I can connect to either of them no problem from a Windows 8 machine, however on a Windows 8.1 machine the Connect option for 2.4GHz and the Discover option for Bluetooth are both greyed out. Likewise the serial port options are greyed out, also Custom Connect under Network. I have installed the Arduino driver and rebooted and have the 2.4GHz USB dongle connected.
mBot is selected under Boards.
Any suggestions as to why I’m unable to connect?
