Sharing is caring! I’ve put a tool-kit together which enables you easily to create a LTE-M Internet Of Things Proof-Of-Concept with a Raspberry PI and a SIMCom SIM7070E which is based on the (currently latest) multi-band multi-mode modem Qualcomm9205.
You can use the preconfigured SD-Card image to test LTE-M connectivity or simply use this SD-image to easily add LTE-M connectivity to your own proof of concepts.

More experienced users can use the provided patch-file to create their own kernel.
