I face problem to connect mBot Ranger to mBlock v5.4.0 running on my PC on Windows 10 home edition via USB. In my case COM7 is offered correctly, but when connecting, error “Connecting error. Please try to connect again” appears.
last available driver CH341SER.INF, version 3.5 2019.1 was also installed.
I reinstalled mBlock several times - without success. Any idea how to solve this?Thank you
