I would like to request help in the construction of payloads.
Right now I have 2 Gateways in operation - one connected to an internal server and the other to the TTN Console.
The two gatways have 3 sensors sending data. Both have on both servers an application created (on each of them) that receives the data and here is where the problem happens
In an already predefined api (example tagoIO) I receive the data already processed and I can make the graphs I want, but when I want to be the one to receive the data in my application, save it in my database and present the data in my graphs, already I can’t because I don’t know how to work with the payload I receive. Can someone help me? any tutorial to follow to make it all easier?
