I am trying to program mBot using Arduino IDE. I am connected to the mBot using USB on COM7, I am able to upload a code created in mBlock 3.4.11 fine, using "Arduino Mode" as the editing mode. I would like to proceed to more complex coding now and for this I want to be able to edit the source code directly. The source code seen in the MBlock application seems to be read only, there is a button which should allow editing the code, called "Edit with Arduino". When I press this button, the Arduino IDE opens and I am able to edit the code. The trouble is I seem to be unable to send the code edited this way into the mBot.
When I use the Arduino IDE Sketch/Upload menu item, the code is compiled, but when sending it, I always get following error:
avrdude: stk500v2_ReceiveMessage(): timeout
Note: I was editing and uploading Arduino code before with both Ardino IDE and VisualStudio visualMicro (now Arduino IDE for Visual Studio) without any issues.
I do not know exactly how is the mBlock application handling the upload, but while doing so a folder with the project is created, which contains the following buildprefs.txt - perhaps this could help to understand what it is doing:
