Rasberry-Pi Gateway Related Problems

Hello,
Hope you all doing well. I need some help from your side and its about The GATEWAY (RASBERRY-PI 3B+ along with IC880A).
I am using this gateway for INDIAN frequency IN-865-867 and try to access through PUTTY.
But, PUTTY shows “Failed To Start the Concentrator”.
Can you tell me why this is happened with me or what are the reason behind this. Below I provided image of it.

Have you checked that the IC880 gets 5Volt? Most of the time I had these problems the voltage was too low.

Yes Sir, i already did it.

SPI is configured in raspi-config?

Yes sir.

Is your Pi connected via WiFi (wlan0), but the gateway using the mac address of the fixed ethernet (eth0)?
Could you perhaps post the global_conf.json and local_conf.json?

Sir, I am using ETHERNET cable for INTERNET connection.
i am using sudo nano local_conf.json”

Hi @sacchidanand_utech, are you using the correct reset pin?

The start of my /opt/ttn-gateway/bin/start.sh script is:

$ more /opt/ttn-gateway/bin/start.sh
#! /bin/bash

# Reset iC880a PIN
SX1301_RESET_BCM_PIN=25
echo "$SX1301_RESET_BCM_PIN"  > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio$SX1301_RESET_BCM_PIN/direction
echo "0"   > /sys/class/gpio/gpio$SX1301_RESET_BCM_PIN/value
sleep 0.1
echo "1"   > /sys/class/gpio/gpio$SX1301_RESET_BCM_PIN/value
sleep 0.1
echo "0"   > /sys/class/gpio/gpio$SX1301_RESET_BCM_PIN/value
sleep 0.1
echo "$SX1301_RESET_BCM_PIN"  > /sys/class/gpio/unexport
...

This is typically a result of:

  • incorrect SPI wiring
  • overly long SPI wiring (including the ground)
  • incorrect SX1301 reset wiring
  • failure to drive the chosen SX1301 reset GPIO
  • excessive SPI clock speed (especially if you were using on the of the newer RAK concentrators, less likely to be an issue with an iC880, but still trying 1 or 2 MHz isn’t a bad idea)

Thank you sir for the reply.
Yes sir, I am using correct RESET pin.

Thank you sir,
I ll check all the parameters that you provided in your message and convey you as soon as possible.
