Basic station giving error in restarting concentrator.

Question

I am trying to make a lorawan gateway simulator which I can connect with AWS Iot core for LoraWan service to recieve uplinks. While running basicstaion in this gateway simulator, I am getting issue in restarting concentrator and noticed a pattern in basicstaion logs.
First it is tries to restart concentrator for which it runs reset_gw.sh script file and gives "/sys/class/gpio/export: No such file or directory" while running it, after printing some logs it gives "SX130x LBT not enabled" and "FAIL TO CONNECT BOARD", and then it closes MUXS connectin with "error in s2e_onMsg" and log "Server sent close: reason=1000", and then tries to connect with INFOS and logs "sent close: reason=1006", after which it again tries restarting concentrator.
Can Someone please explain me about this gpio error and concentrator restart issue.
Below I have given pieces of logs for reference.

Answer

Hi shivam. It seems you are using this Greengrass component: https://github.com/aws-samples/aws-iot-greengrass-component-lorawan-provisioning. This component was developed for a Raspberry Pi, and the `reset_gw.sh` script is trying to reset the radio concentrator board using the Raspberry Pi GPIO17. It assumes a concentrator is attached to the RPi GPIOs (with reset signal on pin 17). Are you running on a Raspberry Pi? Do you have a concentrator board attached? I suppose not since you say you are trying to make a simulator.
