Can I upload a binary file (already compiled and built by another app on my Desktop) by transferring the binary file to my phone for upload? I'm asking because I have a problem with the P.C. that will not allow me to upload via USB from the Desktop to the Nano. It once worked long ago but hasn't worked for months. I've tried everything! If possible then please explain how.
Author, you should have shown - "How to program any arduino.." and that means - to find and install the appropriate driver CH340g for the Android OS (if it is needed) - what is really important. Sorry, for that you get "dis".
