I've had some troubles with the Xbee Api library, actually with the function:ioSample.getSupplyVoltage();

It doesn't work good, because the value it returns it is not the real supply voltage. In fact, when I review the sample with the XCTU, I can see the correct value in the frame, but this value is not the same that I get with the funcion ioSample.getSupplyVoltage()...

I don't know how it works and if there is any other options...

Any suggestions?

Thanks in advance
