Revision:
21:ce51bb0ba4a5
Parent:
18:55f1581f2ee4
Child:

Uses USB comm. Fix rates calc. Power up/down ETH with Afar. Fix sending evt with status. Add num files and bytes of data to status. Can save a local file (i.e. reprogram MBED) via comms. Set config after each comm win (need if cards pow cycle).
