SLIDE 4 CoAP: Overview
- CoAP for embedded devices (e.g. Cortex-M3/M0)
SLIDE 5 CoAP: Overview
- CoAP for embedded devices (e.g. Cortex-M3/M0)
- CoAP Client & Server in one stack! (C-lang)
SLIDE 6 CoAP: Overview
- CoAP for embedded devices (e.g. Cortex-M3/M0)
- CoAP Client & Server in one stack! (C-lang)
- Observe & blockwise support
SLIDE 7 CoAP: Overview
- CoAP for embedded devices (e.g. Cortex-M3/M0)
- CoAP Client & Server in one stack! (C-lang)
- Observe & blockwise support
- More than just a CoAP packet builder/parser
SLIDE 8 CoAP: Overview
- CoAP for embedded devices (e.g. Cortex-M3/M0)
- CoAP Client & Server in one stack! (C-lang)
- Observe & blockwise support
- More than just a CoAP packet builder/parser
- One simple „doWork“ loop – no RTOS needed
SLIDE 9 CoAP: Overview
- CoAP for embedded devices (e.g. Cortex-M3/M0)
- CoAP Client & Server in one stack! (C-lang)
- Observe & blockwise support
- More than just a CoAP packet builder/parser
- One simple „doWork“ loop – no RTOS needed
- Internal memory allocator on static Array (BGET)
SLIDE 10 CoAP: Overview
- CoAP for embedded devices (e.g. Cortex-M3/M0)
- CoAP Client & Server in one stack! (C-lang)
- Observe & blockwise support
- More than just a CoAP packet builder/parser
- One simple „doWork“ loop – no RTOS needed
- Internal memory allocator on static Array (BGET)
- To be used with any packet oriented transport
SLIDE 11 CoAP: Overview
- CoAP for embedded devices (e.g. Cortex-M3/M0)
- CoAP Client & Server in one stack! (C-lang)
- Observe & blockwise support
- More than just a CoAP packet builder/parser
- One simple „doWork“ loop – no RTOS needed
- Internal memory allocator on static Array (BGET)
- To be used with any packet oriented transport
- Main objective: Easy usage & Ressource definition

CoAP: Easy usage
1.
Provide packet oriented binding (e.g. UDP, SLIP) + memory
SLIDE 14
CoAP: Easy usage
1.
Provide packet oriented binding (e.g. UDP, SLIP) + memory 2. Create resources + bind to Request/Observe Handlers
SLIDE 15 CoAP: Easy usage
1.
Provide packet oriented binding (e.g. UDP, SLIP) + memory 2. Create resources + bind to Request/Observe Handlers
- 3. Implement resource handlers…
SLIDE 16
CoAP: LED Request Handler
CoAP logic (e.g. retries, options) is transparent to user! Example LED switch resource
SLIDE 17
CoAP: Blockwise Request Handler
Example blockwise resource
SLIDE 18
CoAP: Postponed Request Handler
Example postponed resource
SLIDE 19 CoAP: Observeable Request Handler
Example
resource (Clock)
SLIDE 20 CoAP: Issues & dev direction
- Implementing new transport bindings / ports is hard
- Client implementation too minimalistic (e.g. no blockwise receive)
Known-Issues
SLIDE 21 CoAP: Issues & dev direction
- Implementing new transport bindings / ports too hard
- Client implementation too minimalistic (e.g. no blockwise receive)
- Built-in serial port transport binding (e.g. for device config)
- Include C Code in Go-lang Wrapper for better (unit) testing
- Use SMS Transport
- Integrate in FreeRTOS & use tickless kernel with periodic sleeps
- Use with our LoRa based Point to Point X-MAC variant
- Write integration guide to support opensource community
Known-Issues Planned Improvements
