LoRaWAN ® Remote Multicast Setup Specification TS005-2.0.0 ©2022 LoRa Alliance ® Page 18 of 21 The authors reserve the right to change specifications without notice. Reserved for future errors bits are unassigned bits in this version of the 582 specification. Those bits SHALL be considered as errors if they are set. The transmitter 583 SHALL set them to '0'. 584 585 If all of the Status&McGroupID bits 2 through 7 are set to '0', the TimeToStart field 586 encodes the number of seconds from the McClassBSessionAns uplink to the beginning of 587 the multicast fragmentation session. This allows the server to check that the end-device 588 clock is roughly synchronized and that it will effectively start acquiring the Class B beacon at 589 the right moment (before the beginning of the Class B multicast session with some margin). 590 591 If the number of seconds from the McClassBSessionAns uplink to the beginning of the 592 multicast session is greater than 16 777 215 seconds (2 24 -1), TimeToStart SHALL be set 593 to 0xFFFFFF by the end-device. This will inform the Application Server that the end-device 594 clock is out of synchronization. 595 596
