Hi. I have a Modular IoT Gateway kit. I want to control by connecting 2 FRDM-KW41Z and 1 MENP KW41Z modules to Gateway. But he was a person who used the modules before me and changed the software. For this reason I can not connect the modules to the gateway (I am getting a join failled error). I downloaded and installed "SDK_2.2_MKW41Z512xxx4" sdk as described. Which example code should I load from this sdk now? What software comes with these kits by default in the first box opening?
