Brief System Communication Overview
1. The FAT API on the Vinculum-II device performs a linear scan of the file system and transfers this data (strings of filenames) to ume on an Android 2.3.4+ phone.
2. Navigating to a new directory in ume requires the file data for the new directory to be streamed from the Vinculum-II device to ume.
3. Once a file is selected, it must be transferred from the USB mass storage device through the Vinculum-II device to ume to be emailed or sent as a multimedia message (MMS).
