CoAP-like Packet Format
Header Size: 8 Bytes
Payload Size: 0 ~ 70 (Max) Bytes
CoAP-like Header
| Name | Size ( bits ) |
|---|---|
| Ver | 2 |
| Type (T) | 2 |
| TKL: Token Length | 4 |
| Code | 8 |
| Message ID | 16 |
| Length | 32 |
Type (T) : 2-bit unsigned integer Transaction Type field. Indicates if this message is
- Confirmable (0): Some messages require an acknowledgment
- Non-Confirmable (1): Some other messages do not require an acknowledgment
- Acknowledgment (2): An Acknowledgment message acknowledges that a specific Confirmable message (identified by its Transaction ID) arrived
- Reset (3): A Reset message indicates that a specific Confirmable message was received, but some context is missing to properly process it. This condition is usually caused when
- the receiving node has rebooted and has forgotten some state that would be required to interpret the message
