jaredwolff Your right, they have completely changed the build method, SDK and how the app images are build. I do not have the required C++, python and GIT experience to even setup their build environment it seems. Reading their description of the process is like reading a foreign language. Matters not, I’m sticking a STM32L412 as a front end to their Verizon certified modem, I can work with CubeIDE, perhaps when I have a few months to spare I’ll revisit using their SDK. Meanwhile I can work with the Feather, I can understand it enough to more forward with the nRF9160. Bonus, not dealing with Thingspace!
