Hub Iniates Communication - Node in Receive Mode

Question: In a non-battery powered application, can the node be left in receive mode such that the hub can initiate communications?

 

Answer:

Yes. In fact, the CyFi Star Network Protocol has this specific configurable attribute available in the PSoC Designer application development software. There are three available power options which change the behavior of the CyFi node device based on this power setting: High-Impedance Battery (e.g, coin cell/CR2032) - results in a 5ms receive mode and then sleep during idle; Low-Impedance Battery (e.g. AAA batteries) - results in a 50ms window of receive mode after a transmit and then sleep during idle; Wall-Powered - results in receive-mode during idle.
