OpenWSN IEEE802154E timings
Note These parameters are BOARD and CPU specific. Values can't be taken directly from OpenWSN since they do not necessarily use the same BSP configuration (timers, clock speed, etc.) For precise synchronization these values should be measured and tuned for every BOARD. To understand the relationship between these values and OpenWSN state machine as well as how they can be measured refer to: https://openwsn.atlassian.net/wiki/spaces/OW/pages/688251/State+Machine https://openwsn.atlassian.net/wiki/spaces/OW/pages/688255/Timing+Constants
#define	SLOTDURATION 20 /* in milliseconds */

Adaptive sync accuracy
Used for synchronization in heterogeneous networks (different BOARDs) Not supported yet, dummy value needs to be provided.
#define	SYNC_ACCURACY (1) /* ticks */
