This toolkit provides an API based on link-local multicast and the Trickle Algorithm (RFC6206) to do network wide broadcast of arbitrary data.
Mira Version requirement:
2.4.0+
There is a example utilizing and showcasing the broadcast toolkit available in the Mira examples repository
The toolkit supports multiple instances of broadcast, where each instance is using its own trickle timer.
The API to be used by the application is provided in mtk_broadcast.h
The packet structure of broadcasted packets:
| 4 bytes | 4 bytes | max 230 bytes |
|---|---|---|
| ID | Version | Data |
To include the toolkit in your application,
- Add the .c files to SOURCE_FILES in your makefile
- Include mtk_broadcast.h in your application
- Provide MTK_BROADCAST_NUM_UNIQUE_BROADCASTS as a compiler argument to set number of unique broadcasts available. (default is 4)
