Bluetooth file transfer

I use ramps 1.4 and full screen LCD with SD card and I routinely print from the SD card.
Is it just possible to send a file to SD card from PC with a BT module to prevent manipulation
between the printer (in my workshop) and my PC (in other room).


  • It makes no difference if you transfer over usb->serial or BT->serial, so it is possible. Knowing how slow this upload is I'd directly upload to sd card.

    You can have 2 connectors configured in firmware and the second could be to a BT module. Just don't use both connections simultaneously - that is currently not supported.
  • Thanks,
    I will try.
