  19. 19. What is Lua?•  High-level programming language•  Scripting•  Simple•  Extensible•  Portable
  20. 20. Extensible by design•  Small– Trivial syntax and reduced keyword set•  Simple but not stupid– Simple enough for new users, powerful enoughfor advanced users (first-class functions,garbage collection, closures, tail calls, coercion,coroutines, metatables)•  Lua core is tiny– Compiled size is ~150kB– Lua uses libraries for its extensions
  21. 21. Lua vs. other high-level languages•  Same core features as Python, Ruby,Javascript •  Better concurrency management– Built-in – doesn’t rely on the OS•  Cutting-edge execution technology &performances
  22. 22. Lua vs. other high-level languages•  Restricted set of libraries– Stay simple, the developer brings his own •  Designed for C integration– Performance– Legacy
  23. 23. Lua for embedded and M2M?•  High-level languages usually tradehardware resources for development& maintenance resourcesLua allows to reconcile high-levellanguages accomplishmentswith embedded constraints
  24. 24. You need an IDE!•  Project structure•  Syntax coloring•  Content assist•  Code navigation•  Code formatting•  Documentation•  Code templates•  Debugger•  Remote development•  Embedded interpreterJune 2012: first release (0.8)Dec. 2012: 0.9 releaseJune 2013: 1.0 w/ Kepler60,000 installations already!

  27. 27. M3DA*Compact … because in the wireless world, data overhead costs money–  Efficient in the transport of binary M2M dataInteroperable … because the M2M communication chain is heterogeneous–  Language-independent–  Tolerant to data schema changes–  Agnostic to transport layer (TCP, HTTP, SMS, …)Secure … because security is #1 concern for M2M adopters–  Ensure integrity and confidentiality of customer data–  Message ticket-id to enable acknowledgementOpen … because vendor lock-in hinders M2M adoption*Micro M2M Data Access
  28. 28. M3DA Layered ArchitectureTransport Layer M3DA Envelope Enables authentication, encryption, …Application Layer M3DA Message Specify access to the tree-oriented datamodelSerialization Layer Bysant Provides an efficient binary serializationbased on contextual information HTTPM3DA TransportM3DA PayloadM3DAMessageCommand/Event/Time stamped dataMessageCommand/Event/Time stamped data…Headers- Device /Server Identification- Securityauth, cipher, hmac, nonce…- Compression algo, dict selection, …TCP UDP SMS*TransportBysant Serializer
  29. 29. M3DA = M2M data optimization•  Object-oriented•  Provides basic classes–  Numbers (Integers, Floating point numbers, Boolean)–  Strings (Binary string)–  Container objects (List, Map)•  User-defined objects–  Allows to structure protocol objects (Message, Responses, DeltaVector,…)•  Serialization is optimized for M2M data–  Small numbers take less bytes–  5 ! 1 byte, 2040 ! 2 bytes–  String size header are adaptative–  1 byte for a 28-byte long string, but 3 bytes for 66k-byte long string.
