Connecting IMST LiteGateway ? Stuck

petekmet · May 8, 2017, 3:56pm

How much costs this GW ?

mattkrebs · May 10, 2017, 1:12pm

I recently ordered two of them. They were € 229 each, which is okay compared to the iC880A alone.
The gateway was not in the web shop, I had to order it by e-mail.

It was a bit of a hassle to get them working with TTN, but at last I succeeded.
I might try the new packet forwarder soon.

Yes it was hard at the beginning
but working perfectly now
please make a backup of the SD card when it is working

Yesterday I received IMST Lite GW, connected to mains and ethernet but could not connect to SSH. What worries me is that I can not see any LED activity on ethernet socket. Both LEDs are dark. Is this normal ?

mattkrebs · May 16, 2017, 10:59am

There might be a contact problem with the SD card.

One of the two gateways I ordered showed the same symptoms as you describe.
I took it apart, checked the RPi and SD card individually, but I did not find any defects.
After putting everything back together it surprisingly worked.

You saved my day! Indeed, after disassembly and connecting HDMI out of the sudden everything started to work ! Thanks a lot.

Ok, got it to work. The reset-stuff was a bit different on my side. Anyway, litegateway-specifc reset procedure can be found here /home/pi/loriot/reset_lgw.sh. Actually, I had to replace original TTN reset code in start.sh with single line calling /home/pi/loriot/reset_lgw.sh start
And had to stop and disable loriot and IoTSemtech services as per original documentation from IMST. Hopefully this will help other in desperation.

we had a great day at the Thinsgnetwork hackathon in copenhagen today; however I got stuck with the lite gateway. We did not make acopy of the original SD card.
Now i am wondering if it would be possible to get a working image from somebody burnt on the SD and change parameters like pwd and wifi and then it should work?
Cheers, Gernot

I have now a running setup, still try to do it better. My solution from scratch:

Fire it up unchanged, download the reset_lgw.sh script (~/loriot/reset_lgw.sh) to your computer and shut it down, disasemble and stuff.

Take a new sd card.

Set it up the GitHub - ttn-zh/ic880a-gateway: Reference setup for iC880a gateways running The Things Network way.

Copy the reset_lgw.sh somewhere to you system. (I put it to ~/scripts/reset_lgw.sh).

Replace > 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

in /opt/ttn-gateway/bin/start.sh with just

PATH/reset_lgw.sh stop
sleep 0.1
PATH/reset_lgw.sh start

It worked for me. If I have time this weekend i’ll try to hack the GitHub - ttn-zh/ic880a-gateway: Reference setup for iC880a gateways running The Things Network scripts.

@tibo Missed the chance to secure the image on the SD card - any way to get the ~/scripts/reset_lgw.sh and how to copy to the location - (am Linux newbie ;–) )
Thx

Here it is, replace GPIO7 with GPIO5

github.com

Lora-net/lora_gateway/blob/master/reset_lgw.sh

#!/bin/sh

# This script is intended to be used on IoT Starter Kit platform, it performs
# the following actions:
#       - export/unpexort GPIO7 used to reset the SX1301 chip
#
# Usage examples:
#       ./reset_lgw.sh stop
#       ./reset_lgw.sh start

# The reset pin of SX1301 is wired with RPi GPIO7
# If used on another platform, the GPIO number can be given as parameter.
if [ -z "$2" ]; then 
    IOT_SK_SX1301_RESET_PIN=7
else
    IOT_SK_SX1301_RESET_PIN=$2
fi

echo "Accessing concentrator reset pin through GPIO$IOT_SK_SX1301_RESET_PIN..."

This file has been truncated. show original

i just used nano and then copy paste. I think some guys would kill me for doing it this way though

This looks like that my board is working or ?

Are you sure the imst light gateway pcb uses Raspberry pin 11? i mine uses raspberry pin 29

mattkrebs · June 26, 2017, 6:25am

For the actual IMST LITE Gateway it’s definitely pin 29 or GPIO no. 5 on the RPi!
The reset script expects the GPIO number, so you need to set IOT_SK_SX1301_RESET_PIN=5.
Same goes for the new packet forwarder, where you should add reset-pin: 5 to the config.

JohnHunt · July 31, 2017, 12:35pm

They have just uploaded a new video: Registering a LoRa® Lite Gateway (LGW) into The Things Network server in 5 min

schulti · July 31, 2017, 2:46pm

Hi there!

I have also just checked out their new video. On minute 4:50 they say that line number 13 in start.sh needs to be removed. This solved the problem for me that was described in this thread immediately (“ERROR: Version of calibration firmware not expected, actual:0 expected:2”).

So you need to comment out this line and the reset works!

# echo "$SX1301_RESET_BCM_PIN" > /sys/class/gpio/unexport

LgS

johnsondavies · August 28, 2017, 4:32pm

I’ve made a transcript of the procedure in the IMST video which might be useful if, like me, you prefer to follow text instructions, or you want to be able to copy and paste commands across to the terminal:

ChristianH · October 14, 2017, 12:26pm

Just a hint:

I also have not been successful with the video-procedure for the TTN-forwarder.

But with the Sentech-forwarder which is pre-installed the gateway (I have a post june 2017 version) runs more or less out of the box with only a few steps:

enable rw-access to the SD-card
stop and disable loriot
enable IoTSemtech
(these steps are in the quickstart-manual)

edit /home/pi/github//packet_forwarder//lora_pkt_fwd/local_conf.json
(you even don’t have to use vi, mc is pre-installed)

set appropriate values in the local_conf.json:
For a working gateway ID put FFFE between the first and the second half of the device’s MAC (which was printed onto the device at my IMST Lite)

start IoT semtech

O.K: It’s not TTN’s forwarder but it worked

arjanvanb · October 14, 2017, 12:37pm

…and the future of TTN’s forwarder (if that’s the one you’re referring to) is unknown anyhow:

paulb · November 11, 2018, 8:04pm

I spent some time finding back this post after reinstalling my Pi. Reply to be able to find it quicker in the future.
For my board (got it on Ali with the gateway as a set) this pin works.
