RPL DODAG router app for an OpenWSN 6TiSCH network. Reads incoming data from root mote, and performs routine management.
Since OpenWSN operates RPL in non-storing mode, reads ICMPv6 RPL messages to maintain a routing table for the network motes.
Also:
- Prints error notifications from mote to daghead log.
- Sets the root mote as DODAG root. Assumes root mote is not already DODAG root. Presently avoids use of Constrained Join Protocol for network motes by using a static network key hardcoded into mote firmware.
See implementation notes in README-openwsn.md.
