After installing mBlock, I find the version of Arduino IDE is out of date. Will it be safe if I replace the old version with a new one in the folder located at Program Files (x86)/mBlock?
The Arduino software integrated by mBlock is version 1.6.5, please don’t replace the integrated arduino software with newer version since it may cause upload error.
If you want to use newer version Arduino software, it is suggested to install a newer version Arduino software on the other place of the computer.
Got it. Thanks.
