Error compiling for board WisBlock Core RAK4631 Board

Ohhhh sorry for the confusion Sir. Even myself is still lost. What do you mean by LoRaWAN server application?

Scratch the word application.

TTN is a LoRaWAN server running in the cloud
Chirpstack is a LoRaWAN server that often is used locally on RPi’s

If you say local server what does that mean?

Usually there are 3 parts in a LoRaWAN network

Ohhh I see. When I said “to our local server” it means our own server at the office. I wanted to see the data of my end nodes to our local server instead on TTN. So based on the image you have sent, I think it’s best to utilize Chirpstack server since it can be local or in cloud. What does Application Server mean?

Apologies Sir since I have lots of questions as of now

Both TTN and Chirpstack have the application server integrated.

If you go for Chirpstack, the network server handles the incoming packets, the application server is responsible for the device registration, checking and answering join requests from the nodes and it can forward data to other applications, e.g. Datacake.co
