Cannot connect to mBot after using Arduino IDE Today I bought an mBot (from Makeblock) the one that uses 2.4G serial connection. After assembling it, I connected to it using mBlock (software based of Scratch) and I could control it using keyboard triggers. Then I went in Arduino IDE and used it to run some scripts on the mBot. 

Next I tried to switch back to mBlock software, but now it cannot connect to the mBot anymore. Whatever Scratch-like scrips I build, they don't run anymore in mBlock.

Did I miss anything? Is there anything I can do so I can start using mBlock again?
I received some really good piece of advice on the official forum and it solved my problem, it now works:


  When you go back to using the mBlock (Scratch) environment you will
  need to reload the firmware (Upgrade firmware from the Connect menu
  item). At least that’s what I’ve had to do. Oh, and make sure that you
  have shut down the Arduino environment to release the serial port.
