Does the CyFi Star Network Protocol support network broadcasting?
No. To implement this functionality, the hub would have to have the message requiring delivery and then iterate through a loop that would target each individual node and transmit the required data. Broadcasting data negatively affects low-power operations for nodes as well and thus why it is not currently supported by the CyFi Star Network Protocol. Broadcasting functionality requires nodes that wish to participate to always be on and thus not preserving energy in the ultra low power sleep modes. Either way, it is possible to implement similar functionality but the number of nodes in the system and the power budgets available must be carefully considered.
