Important Things to note: 

  1. The SD card cannot be hot-swapped, i.e. the SD card should be inserted before you power on the glove and then only removed once the glove is powered down.

  2. When the SD card is logging you should be able to see the light on the back of the glove alternate between blue and green (normally it just flashes blue)

  3. Also, there is no need to worry about the C->D switch that just pertains to the USB power/communication settings.
