Yes, that's the API I was talking about.
As I said before I haven't work with all the functionality that the XBees provide like the I/O and analog ports in the XBee because I use it only to communicate to a better MCU.
So I haven't tried the ZNetRxIoSampleResponse class , I didn't know about your API until yesterday if not I would've tried.
I still have a problem with Rapp's API and is that the transmition speed is slow compared to what Digi claims this modules are capable of. Some other users of the API have agreed with me on this so if I need some more transfer speed I'll try your API.
