I have 8-channel gateway which is Raspberry Pi 3B+ with iC880a (https://market.thingpark.com/solutions/tracking/ic880a-lorawan-concentrator-868mhz-404802). 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: https://github.com/dragino/rpi-lora-tranceiver/blob/master/dragino_lora_app/main.c 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!
