I'm trying to work out how to make a file I can upload directly to the board. I want to send the same program to a few hundred of these bad-boys and don't want to have to compile+upload every time. How can I create a file and just send it?

It look like :

Code: Select allesptool -vv -cd ck -cb 115200 -cp /dev/ttyUSB0 -ca 0x00000 -cf /tmp/build7954594845470280878.tmp/Sketch_Buffet.cpp.bin


Of course, you can copy the resulting binary from this /tmp folder as a backup for future uploads.
