Using XCTU to enable I/O Sampling by setting IR to some value (0x32-0xFFFF) works fine. But afterwards, trying to disable I/O sampling by setting IR to 0 does not work. Seems 0 is being ignored or sensed as an out-of-range value. Do you have a fix for this problem. I need to be able to change the sampling rate and then disable it without having to reset and reload firmware.
Which XBee product and related firmware are you referring to?
The problem of zero value (0) being ignored was fixed by upgrading to XCTU v6.1.1.
