IMST Lite Gateway setup

martinklaus · March 12, 2020, 8:38pm

I’m trying to get Gateway OS running on an IMST Lite Gateway with Raspberry PI 1.
The “chirpstack-concentratord” is crashing continuously.

Mar 12 20:33:31 raspberrypi user.err chirpstack-gateway-bridge[751]: time="2020-03-12T20:33:31Z" level=error msg="backend/concentratord: event socket dial error" error="dial event api url error: zmq4: could not dial to \"ipc:///tmp/concentratord_event\": dial unix /tmp/co

In the shield setup I’m using point 3 what is IMST Lite Gateway.

The Config is:

# Concentratord configuration.
[concentratord]

# Log level.
#
# Valid options are:
#   * TRACE
#   * DEBUG
#   * INFO
#   * WARN

#
# When set to true, log messages are being written to syslog instead of stdout.
log_to_syslog=true

# Statistics interval.
stats_interval="30s"

  # Configuration for the (ZeroMQ based) API.
  [concentratord.api]

  # Event PUB socket bind.

  # Command REP socket bind.

  867300000,
  867500000,

]

# LoRa std channel (single spreading-factor).

spreading_factor=7

# FSK channel.
[gateway.concentrator.fsk]
frequency=868800000

datarate=50000

I hope somebody can help me.

The logs you are providing are of the Gateway Bridge unable to connect to Concentratord. Could you provide the error log of the Concentratord? That might explain why it is crashing. I have a Lite gateway and with the latest Gateway OS and selecting the IMST Lite Gateway using the gateway-config utility, it starts fine.

How i get the error log for Concentratord?

brocaar · March 17, 2020, 10:27am

See tail -n 100 -f /var/log/messages for all log output (replace -n 100 with a higher number to get more history). Or see sudo monit summary for an overview of the running services.

What you could try:

Edit: make sure you are executing these steps as root user (e.g. by running sudo su).

Validate if concentratord is running (it is on my gateway as you can see below but probably it is not in your case, else monit would show OK):

raspberrypi:/home/admin# ps aux |grep concentratord
root       433  2.6  0.9  39700  3996 ?        Sl   12:18   0:03 /usr/bin/chirpstack-concentratord-sx1301 -c /etc/chirpstack-concentratord/sx1301/global.toml -c /etc/chirpstack-concentratord/sx1301/band.toml -c /etc/chirpstack-concentratord/sx1301/channels.toml

Disable the monit for concentratord (to make sure the next steps are not failing because monit is trying to restart concentratord):

raspberrypi:/home/admin# monit stop chirpstack-concentratord

Validate that the correct default config is set:

raspberrypi:/home/admin# cat /etc/default/chirpstack-concentratord 
# reset the LoRa concentrator on Concentratord start
CONCENTRATOR_RESET="yes"

# reset pin
CONCENTRATOR_RESET_PIN=5

# power enable pin
CONCENTRATOR_POWER_EN_PIN=18

# concentratord version
CONCENTRATORD_VERSION="sx1301"

Reset the sx1301:

raspberrypi:/home/admin# /etc/init.d/sx1301-reset stop && /etc/init.d/sx1301-reset start

Edit the global.toml config and set log_to_syslog to false (also validate that model="imst_ic880a_eu868":

vi /etc/chirpstack-concentratord/sx1301/global.toml

Start concentratord from the CLI:

raspberrypi:/home/admin# /usr/bin/chirpstack-concentratord-sx1301 -c /etc/chirpstack-concentratord/sx1301/global.toml -c /etc/chirpstack-concentratord/sx1301/band.toml -c /etc/chirpstack-concentratord/sx1301/channels.toml

i have the same issue

after executing this line i get this message

admin 17475 0.0 0.0 2188 440 pts/1 T 05:43 0:00 vi /etc/chirpstac....

and after trying to start concentratord i get this

brocaar · March 25, 2020, 9:05am

Please take a look again at my previous comment. It contains a few crucial step that you must validate. ERROR: Version of calibration firmware not expected, actual:0 expected:2 could mean the sx1301 was not properly reset. Please validate your configuration with the above steps

overdull · March 25, 2020, 9:50am

thanks for fast replay, everything is configured as yours.

martinklaus · March 25, 2020, 10:09am

My Error looks the same like the Error from overdull.

The reset script is using the content from the environment variable "$CONCENTRATOR_RESET_PIN". But where is it set?

If i switche to root with sudo su and run the command, than i get exactly the same error message.

See the cat /etc/default/chirpstack-concentratord step

martinklaus · March 25, 2020, 1:51pm

OK, but it’s not working. You know if there are different revisions or variants? My gateway is based on a raspberry pi 1. It’s on of the first that was produced.

brocaar · March 25, 2020, 4:17pm

Just to confirm:

is you configuration exactly the same as mine (see previous comment) ?
Have you tried /etc/init.d/sx1301-reset stop && /etc/init.d/sx1301-reset start (as root user)?

martinklaus · March 25, 2020, 5:41pm

Same config (copy below) and reset (start/stop) runs without error.

raspberrypi:/home/admin# cat /etc/default/chirpstack-concentratord 
# reset the LoRa concentrator on Concentratord start
CONCENTRATOR_RESET="yes"

# reset pin
CONCENTRATOR_RESET_PIN=5

# power enable pin
CONCENTRATOR_POWER_EN_PIN=18

# concentratord version
CONCENTRATORD_VERSION="sx1301"

brocaar · March 26, 2020, 8:24am

Mine is also with the Raspberry Pi 1 (I received it recently). I’m not sure why it works for me but not for you.

Maybe there are different revisions of the IMST Lite gateway? (with different reset pins). My convertor board (between the iC880a and the Pi 1) has printed Part: 10066, PCB v6.

martinklaus · March 26, 2020, 9:31am

Maybe Pictures are easier than writing. My PCB is V1.4 an i have no idea where i can find the printed Part number.

brocaar · March 26, 2020, 9:53am

I have asked IMST about the difference between V1.4 and V6 In case it is mapped to a different reset pin, it would explain the difference in behavior.

Do you know which reset pin was used previously on your gateway?

martinklaus · March 26, 2020, 10:07am

I asked also for it , the will be happy about that.
We should checkout http://www.technoblogy.com/show?1XKI and https://github.com/ttn-zh/ic880a-gateway/tree/spi for the pin layout. With this script everything is working.

Could you try to update /etc/default/concentratord to:

# reset the LoRa concentrator on Concentratord start
CONCENTRATOR_RESET="yes"

# reset pin
CONCENTRATOR_RESET_PIN=25

# power enable pin
CONCENTRATOR_POWER_EN_PIN=18

# concentratord version
CONCENTRATORD_VERSION="sx1301"

Then:

re-run the sx1301-reset stop and start command
try to start concentratord from the cli

If that works, run monit start chirpstack-concentratord. When restarting the gateway, concentratord should be automatically started on boot.

Nevermind, I didn’t fully read your first link, see:

Change the reset pin to 5 by editing the line near the top of the file to:
SX1301_RESET_BCM_PIN=5
