We made our robot-kit (arduino nano) mBlock5 Extension, and we used it for 1~2 months without problem.
Recently we used mBlock and found robot-kit is not working correctly any more, and we found that mBlock did not generated/inserted our defined code for loop() function in Extension Builder panel. (refer to below image)
I am not sure… but I think, may be after mBlock is updated, this problem happened.
Anyway, please check why _loop() code is not generated at all.
Thank you very much in advance.
