Gateway failed to start concentrator

zii · May 14, 2023, 7:22am

Hello,
i’m trying to create my ttn gateway, i’m using the kit LoRA/LoRaWAN gateway 868MGz with raspberry Pi3, i’m following this video #115 How to build a LoRa / LoraWAN Gateway and connect it to TTN? Using an IC880a Board - YouTube
But in the last step when i run this command sudo tail -f /var/log/syslog i get this error

That means the Pi can’t talk correctly to the hardware. Check if you enabled SPI on the Pi. Next check the reset matches your hardware.

Hi Kersing,
I am trying to build a ttn gateway using RAK5146L with 433-435MHz antenna, my Location is Ghana so I am trying to use the EU433 frequency band (UTI) with raspberry pi 4. The gateway connects to ttn but does not stay coneected, it doesn’t session alive. I also get errors like failed to start concerntrator, unrecognised frequency band, shown below is the error logs from raspi and error screenshot from the ttn console status of the gateway:

Basic station does not aupport EU433 out of the box. Another case would be needed. J_EU433 is defined already so adding the option in s2e.c is straight forward.
