I've created a configuration generator for PMP450 devices that will create .cfg per ESN/MAC of each device. This proved useful for zero-touch configuration of devices with static IP addresses. I figured I would share it with the community, so I've hosted it in a GitHub repository. You just need python installed in order to run it. NOTE: I used an AP in DES to run ICC (since it doesn't seem to work in AES), and then I switched it to AES to communicate with the SMs since my configuration was set to AES.
