Android phone: application and forwarder

• Application (RFDuino test app - like):

  • Scanning:
    • shows list of devices
    • For each device
      • create a BLE transport / face
    • Registers the announced name (UUID) and the face in the FIB
  • User event:
    • select the desired arduino from the list
    • click on sendInterest button:
      • create an Interest with name UUID/XX
      • Sends the Interest

• Forwarder:

  • OnReceiving Interest from a local application:
    • standard procedure: lookup on the FIB, sends the Interest using the correct transport/face
  • On prefix registration if not already present, create a FIB entry

• BLE Face / Transport

  • On sending Interest out:
    • if device is not connected, connect to the arduino device associated with this face
    • After the connection is completed:
    • (space optimization) remove the first component from the Interest name (UUID)
    • create packet (if bigger than 20 bytes -> fragmentation)
    • set a timeout
  • On receiving a data packet:
    • handle fragmentation
    • when the packet is complete:
      • create a compliant NDN data packet
      • Add the UUID to the name prefix (first component)
      • sends data to the forwarder
      • disconnect the device
      • remove the timeout
  • On timeout:
    • Data transfer failed : disconnect the device
    • Notify the application? (HOW?)
