Hello,
Please I have a project I am currently working on with the RAK 831 connected to my raspberry pi to receive sensor data from 4 LoRa nodes. In this project, i want to configure the LoRa gateway to work without internet or wifi (an independent system) where the Nodes send the data and the concentrator gets the data and i capture the data on the raspberry pi with apps such as NodeRed. i don not want to forward the data to either TTN or Loraserver. the project is to be deployed in a remote area without internet. So i want to know if the RAK 831 can be configured to receive data without connection to the internet. I want to make my project on LoRa and not LoRawan.
Thanks for your help in advance.
Hei @cherechi,
The RAK firmware comes with a Built-in Chirpstack, that is deployed locally, just use that. Should work out fine.

Thanks for your reply. Please how do i use this. Any more specifice way to access this. I will also like to send controls back to the nodes from my nodered through the concentrator. Is this also achievable? If yes, I will appreciate a more descriptive explanation of how I can get this done.
Thanks in advance
Also, with this you just said, can the concentrator recieve and send data without internet for setup and usage
Hei @cherechi,
You can refer to this one for a rought overview of what to do:
https://doc.rakwireless.com/rak2245-pi-hat-edition-lorawan-gateway-concentrator-module/connect-the-lora-gateway-with-chirpstack
Basically you need to configure the Gateway to work with the Built-in Chirpstack, which should be by default if you haven’t modified the Firmware via the "sudo gateway-config command ".
All configuration to the Network Server and Application server can be done via the Web interface using a browser:
IP address of your Gateway at port 8080. Thereon it is a normal ChirpStack.
As for Node Red, I can’t help there, I definitelly know that what you want to do is possible, however my brain is not big enough to tell you how to do it as I don’t know.
Perhaps some of the smarter people on the forum will pitch in 
I hope this has been at least a little helpful to get you started. That link is to a document for the RAK2245, however the ShirStack portion of the configuration is the same for RAK831, maybe go through the whole things just in case

Thanks very much
This will go a long way to help.
Thanks once again
