Reset is just a reset. Depending on your XBee settings, it may have no impact. It is certainly NOT like the Ident button, and it never does a ‘factory reset’.
If your adapter is an end-device, it will still assume it can rejoin the previous parent.
If your adapter is a router and JV=0, then it acts much like end-device - it resets but assumes it’s old associate peers still exist. If JV=1, then it confirms it can locate a coordinator and changes channels if required to find one.
