In the XBee AT commands specification it is stated the following:
(...)The voltage supply threshold is set with the V+ command. If the measured supply voltage falls below or equal to this threshold, the supply voltage will be included in the IO sample set. (...)
I'm not sure of it's meaning. Does it mean that if it goes below the define threshold, every IO Sample transmitted will also include the voltage value?
If that's true, to which pin will it be associated?
And, although, the following scenario may not make sense, what if a specific node only transmits a IO Sample once / month? Does that mean that in the meanwhile no "Voltage Supply" value is transmitted?
Thanks for clarifying.
