I have a question about the XBee 865/868LP modules, U.Fl vs RF pad versions. We are redesigning our circuit board to transition from the U.Fl version of this module to the RF pad version. Will there be any firmware mods required to make this transition? I.E. are there any differences between the modules that I need to know about when writing the firmware (different amplifier settings, different RF switch settings, etc), or are the two modules identical except for the RF connection? Thanks!
