[ZNM] What HW/FW will you send me? If I receive HW 3.2 that’s a different product than 2.1 – according to the PCN there is a difference in layout, PCB material and thicker chipset. We will send the latest version of the module (HW and FW). New versions will always be backward compatible. If changed a PCN will be issued.
