Abstract
Systems and methods are disclosed for synchronizing communications between a parent device operating on a time-slotted channel hopping (TSCH) protocol and a low-energy network device operating on a low-energy channel hopping protocol. The parent device sub-divides TSCH timeslots and communicates with adjacent TSCH devices during a primary portion of the timeslot and listens for communications from a connected low-energy device during the secondary portion of the timeslot. Upon receiving a synchronization request from a low-energy device, the TSCH device transmits a synchronization response comprising synchronization data. The synchronization data allows the low-energy device to synchronize communications with the TSCH network by synchronizing with the channel hopping pattern of the TSCH protocol.
