IMST Lite Gateway setup

ChirpStack Gateway OS

No I’am changing it to 5 in the script, look on the first link.

You could actually try to reset the sx1301 with:

#! /bin/bash

# Reset iC880a PIN
SX1301_RESET_BCM_PIN=5
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

I see there are some minor differences compared to /etc/init.d/sx1301-reset (which is based on https://github.com/Lora-net/lora_gateway/blob/master/reset_lgw.sh).

23

after some research i find out that my spi sends only zeros, tommorrow I will try with different rpi.

to check spi working properly:

wget https://raw.githubusercontent.com/torvalds/linux/master/tools/spi/spidev_test.c

compile it:
gcc -o spidev_test spidev_test.c
and run it:
./spidev_test -D /dev/spidev0.0 -v

@overdull Die you have something new about it? Which revision of the gateway do you have?

25

I have the same revision of gateway as you. I managed do get it work, I install fresh version of raspbian and istall packet forrwarder and lora_gateway from github and only chirp-gateway-bridge because thats all I need, and then use this script to power up gateway.

SX1301_RESET_BCM_PIN=5
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 
./lora_pkt_fwd

first few times I get same error ver:0 expected:2
but after few tries it starts

26

You used BasicStation or Semtech UDP Packet Forwarder as packet forrwarder?

27

I used semtech. This is guthub project i used

to install it just cd to folder and run make

28

I make the same thing, but i getting the old error.

ERROR: Failed to load fw 1
ERROR: Version of calibration firmware not expected, actual:0 expected:2
ERROR: [main] failed to start the concentrator

I’m running the rest script and after that the forwarder.

29

i got this error few times before it eventually starts

30

Try it a few times like this?

#!/bin/bash

for i in {0..100}
do
   sleep 10
   echo "RESET"
   cd /home/pi
   ./reset.sh
   echo "FWD"
   cd /home/pi/packet_forwarder/lora_pkt_fwd
   ./lora_pkt_fwd 
done
31

Big news fist script is working, second not.

I installed wiringpi and run this script and it’s directly working.

#!/bin/sh
RESET_PIN=5
echo "Accessing concentrator reset pin through GPIO$RESET_PIN..."
WAIT_GPIO() {
    sleep 0.1
}
gpio -g mode $RESET_PIN out ; WAIT_GPIO
gpio -g write  $RESET_PIN 0 ; WAIT_GPIO
gpio -g write  $RESET_PIN 1 ; WAIT_GPIO
gpio -g write  $RESET_PIN 0 ; WAIT_GPIO

Not working script:

#! /bin/bash

# Reset iC880a PIN
SX1301_RESET_BCM_PIN=5
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

Now the big question, why?

32

Hi Martin,

I’m late to this thread but current dealing with a similar but different issue. However, on your point about the two scripts. Could it be because in the first script you are using WiringPi, for which “5” has a different meaning to the second script’s “5”? In the second script, it is referring to Pi’s GPIO_5". In the first, WiringPi’s definition of “5” is abstracted from the hardware, and depends on the platform. On a model B or B+ Pi, .WiringPi’s “5” is actually GPIO_24.

Regards,

Mike

I’m having the same problem here, thing is, the “/etc/init.d/sx1301-reset” file does not exist, I’m using the latest chirpstack OS, and the pin is set correctly and the “chirpstack-concentratord” only has the CONCENTRATORD_VERSION in it and it seems correct, yesterday, I had the same problem but it booted correctly after doing all the steps you put in except the sx1301-reset and it was OK in monit but now it says it does not exist, and i also had an error at the end when I tried to start the concentrator from the CLI so I got this:
