As usual, even best-laid plans face hardship, so now I can wireless upload g-code files to the USB memory connected to a DDCSV1.1 CNC controller. But, once I factor in not to upload a code line before I have got the remote echo of it, things get really slow. Like ten minutes per megabyte. Yes, I wanted it to be wireless. I could accept a not so fast upload speed, but 13 Kbps is not ok as we handle files in the 1-10 MByte range usually. A few seconds is ok, but half an hour or more is not. So I came up with yet another approach that would recycle some old-tech that I discarded years ago: There was a USB dongle that would accept an SD card and it would work as a USB pen driver but with a twist: the unit did also have wifi connectivity. So the users could access the content of the SD card wirelessly as a network disk. That was cool and made totally unnecessary (apparently) my previous work but, there was a catch: The device would work either as a pen drive (as soon as you connect it
