@peekay123 There are no instructions from 4D systems other than how to get the firmware to load from the SD card.
I assume we can connect the Photon & 4D systems SD card to the same SD card pins and get it to work correctly? I figured I could get them to work together one way or another if I could get the Photon to reliably download data from FTP.
And I think your right about the FTP code not having enough exception handling to maintain a long connection. It would stop prematurely even on smaller sized files so it was all over the place on when it would download 100mb and when it would stop at 4 MB before it was done using the local server setup.
Are there any ready to work libraries for the TCP stream downloading you are referring to?
Also, can this code be used on a Photon or Electron only for FTP downloads?
