  1. Implementing Many-to-Many Invocation Over Bluetooth Joshua Zatulove Louie Gosselin Anthony Stamp Evan Teran

  2. Original Theory • Bluetooth device connectivity BUNK Scatternet Piconet

  3. Doing It With the XJB Stack Yo! I’m here Anyone else? Yo! I’m here Anyone else? Peekaboo, I see you. Peekaboo, I see you.

  4. Connecting Devices Anyone want to connect to me? I’m going to try to connect with that guy. I’ve got some ‘chunks’ to send him.

  5. How the XJB Stack Works

  6. XJB Stack - What we use • Discovery Manager • Device Manager • L2CAP

  7. Handling connections • Server threads • Client threads • Device Discovery • Only good for multipoint devices.

  8. Bluecheese Chunks • The device ID of its origination. • Its sequence number from its origination. • A hop counter set at its origination. • A counter for the number of exclusions. • The exclusion list which is a vector of all the devices the previous sender sent this to. • The data packet size. • The data packet.

  9. Reducing Redundancy • Lookup table • Packet originator • Packet sequence number • Hop Count • Exclusion List
