LoRa PHY layer

I serendipitously stumbled upon a great talk from last year’s CCC congress by Matt Knight. It delves into the PHY layer of LoRa and he explains how the protocol was reverse engineered. Impressive work, and very educational! It also means that I will probably be able to use an SDR for testing.



It’s been a while since I last used my blog. This is wrong, because it is a great way to document my experiments. Making it public can (possibly) help others on the same journey, but more importantly I can fall back to it at a later time.

Therefore, my new years resolution for 2017 is to use my blog more. More specifically, I intend to use it to document my ventures into LoRa-land, an exciting new radio protocol for low power communications. So there, now I only need to follow up on my promise!

I bought two LoRa modules from Ebay. once I got them, I realized that the pin header has a 2mm pitch instead of the standard 2.54mm. My first quest will therefore be to interface it somehow to a breadboard…
