I have changed my mind regarding the project I had started with LoRa modules.
I will use it as part of a commercial product for the company I am working for, and since this product will need certification, I decided to change and choose another module. I will leave HopeRF’s RFM9xW in favor of Microchip’s RN2483. RFMs are cheaper but the Microchip solution is not so expensive, and comes pre-certified for use in most of the world that cares for such things.
I think the time is now to get some of these babies and work on them a little.
