I successfully set up a gateway with a raspi3 and an ic880a. I successfully programmed a T-beam as a node. I successfully registered the gateway and the node at ttn. I see the gateway and the node payload on my console and I can download the data from ttn.
Is it possible to run the raspi3 as gateway without the ic880A or any other radio frequency frontend? I want to upload only raspi3 intrinsic data to ttn, i.e. test data or temperatures. Are there other projects which run a ttn gateway on an arbitrry platform without an RF frontend?
