HI, When reading the new updated minimal, we have observed that the timekeeping bit within the IE TSCH Slotframe and Link is not set: "...The "Timekeeping" flag is never set, since the time source neighbor is selected using the DODAG structure of the network..."
If you take a look to the current standard: - Point 5.2.4.14, TSCH Slotframe and Link IE: "...RX links shall have the Timekeeping linkOptions bit set...". - Point 5.1.4.2a, Synchronization in a TSCH PAN: "...Note that a device sending Enhanced Beacons to advertise a TSCH PAN should set the Timekeeping bit in the Link Option field (as described in 5.2.4.14) for the joining devices' receive link so that joining devices can maintain time synchronization until additional time source neighbors are configured by a higher layer...". Therefore, the link within the beacon sent by the (PAN)coordinator should be set as timekeeping too based on the current standard. Cheers, Jose.
