Getting started with iC880a + Raspberry Pi 3 gateway

I have 8-channel gateway which is Raspberry Pi 3B+ with iC880a ( I am also open to purchasing new gateways if the following problem gets solved using the new ones.

I started looking into LoRa last week and currently looking to connect one 8-channel gateway with 20 nodes without using The Things Network. I have looked into LoRaServer as well and I would like to know if there is a quick start guide with LoRaServer using which we can hold communication between node and 8-channel gateway? Or is there any code example which enables communication between node and gateway (or client and server) without using TTN?

If not, I believe I might have to code something similar to the following: such that my code should contain 8-channels instead of one. Would following the aforementioned script be a good idea? Any guidance/information would be highly appreciated!

Please see, altough this still the first test-release, I believe it is the easiest way to get started :slight_smile: There is also an image which comes with all the LoRa Server components pre-installed on the gateway.

Alternatively, you could use the base image and follow one of these guides to setup LoRa Server:

Thank you for the reply and the link. I understand from reading that the packet forwarder will be pre-installed within lora-gateway-os-full and I would not have to worry about scripting from scratch which is pretty neat. However, I have two questions:

  1. Does LoRaServer has any airtime or number of messages per day policy/limitations? I tried to look it up but have been unable to find any such information.

  2. Since I am still learning, I have been wondering if this gateway would be able to receive messages from any node as long as the SF and frequency matches? My nodes are Raspberry Pi 3B+ + LoRa GPS Hat that sends a 200 byte message every minute. I was wondering if there would be any issues?

Thank you

  1. No, this is (currently) not implemented.
  2. The iC880a concentrator board has the same chipset as most other (commercial) gateways, so you are good with this one :slight_smile:

I’m following the same maze i think. Between node and gateway you don’t need TTN i think, but you need some servers to connect your node (client) to. I stumbled upon this one :, maybe something to look at. Maybe I point you in the wrong direction, but it helped me.

The ChirpStack Gateway OS is the easiest way to get started :slight_smile:

After flashing the SD card, you login run “sudo gateway-config” and you configure your iC880a shield. The only thing you need to know is GPIO which is connected to the iC880a reset.

When you flash the “-full” image, it already comes with all the ChirpStack components installed :slight_smile:
