Hi, Installed this git on my raspberrypi 0 w whit iC880A and iC880A LoRaWAN Gateway Backplane v2.0 some time ago, and i guess i need to update it from time to time... are there any place somebody has written a how to ?

E

I have noticed that the TX gain table in the global_conf.json file is exceeding the max RF output power that the internal power amplifier on the iC880a can handle. See the Datasheet https://shop.imst.de/media/pdf/22/67/a8/iC880A_Datasheet_V0_50.pdf at page 18.
The datasheet contains also an example how the tx_lut should look: https://shop.imst.de/media/pdf/22/67/a8/iC880A_Datasheet_V0_50.pdf at page 26 to 27.

And the datasheet also mentions on page 21 that the rssi_offset of both radios should be set on -169 instead -166.

Should the global_conf.json be modified to avoid damage to the amplifier or I'm missing something?

Edit 1: I have found the right settings to do in the global_conf.json: see https://www.wireless-solutions.de/downloads/Evaluation-Tools/LoRa_Lite_Gateway/WiMOD_LiteGateway_QuickStartGuide_V1_5.pdf at page 15.
They use this settings in their own LiteGateway which use the same iC880A concentrator board.
This is also confirmed in the datasheet of the LiteGateway. See the "Transmitter power level configuration in TX gain table" in https://www.wireless-solutions.de/downloads/Evaluation-Tools/LoRa_Lite_Gateway/WiMOD_LiteGateway_Datasheet_V1_5.pdf at page 9.

So the tx_lut in the global_conf.json should look like:

        "tx_lut_0": {
            /* TX gain table, index 0 */
            "pa_gain": 0,

Thank you.

Hi I found a problem when running install.sh

It couldn't find eth0 on a raspberry pi 3

I was getting the error:
ERROR: No network interface found. Cannot set gateway ID.

I found the fix in this link:
https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=191639

You may want to consider mentioning it in the installation instructions, as it took me about 4 hours to diagnose the problem and find the fix.

Thanks
Riccardo

Currently the service file is installed to /lib/systemd/system/, but this directory is not meant for user defined services.

Custom services should be installed to /etc/systemd/system/ instead.

See https://www.freedesktop.org/software/systemd/man/systemd.unit.html

Why I must fill out the settings like email, lat/long and so on? what is this information used for? I can edit it all on the TTN account.

Hi,

is it possible to save the data from node locally (in raspberry pi sd card) before sending the data to TTN?

Hi,
I installed ic880a-gateway as shown and I am testing it using an arduino uno node with an SX1276.
Sending informations from my node to the TTN works fine but from ic880a-gateway to the connected device doesn't work, but i have to mention that in the "start.sh" code interface, the gateway seems to correctly send the message.
do I have to change my node ??
any advice could help!
thanks.

Hi there!
Am I right that this repository is not up-to-date and working with its resources?

I found that install.sh is referring to a binary called poly_pkt_fwd, but it seems that the code
at https://github.com/TheThingsNetwork/packet_forwarder doesn't compile to a binary callled poly_pkt_fwd (anymore?).

What would be the current approach if i want to build a gateway with RPi and ic880a?
I guess the stuff at https://github.com/TheThingsNetwork/lora_gateway is still usable?
What packet forwarder is the best choice atm?

Thanks in advance for any hints!

Hi all
About the case that in the beginning of start.sh there is an internet connection testing, by pining to google.com ...

• there are network environments where net admins do filter icmp traffic to google (maybe not in the field, but while testing gateways in laboratories)
• there is a workaround to this problem by ralphtheninja's pull request here and reixd 's suggestion

wouldn't be more generic to test gateway's connectivity by pinging to a more TTN related url, and what would that be ?
I believe this should be less possible to be filtered and if no ping to it, then the gateway is facing a real connectivity problem !!

regards

git clone https://github.com/ttn-zh/ic880a-gateway.git ~/ic880a-gateway
after entering github user/pass

and I get back a message:
fatal: repository git clone https://github.com/ttn-zh/ic880a-gateway.git/ not found

The above command comes from:
https://github.com/ttn-zh/ic880a-gateway
section: Clone the installer and start the installation

Can anyone advise what the issue is..
Thank you in advance

Hello,
Thank for sending the black pane. I received it satureday.
I just configured my second gateway. For now it will remind at home close to my first gateway.

During the installation, I answered yes for the remote configuration and at the end the gateway was renamed to ttn-gateway. However, now I have two gateway with the same name, name I switched of the first.

I red your doc and you wrote

By default, the installer changes the hostname of your Raspeberry Pi to ttn-gateway (to prevent collisions with other Raspberry Pis in your network). You can override this in non-remote configuration mode.

As I chosed remote configuration, I should not rename it? What happen if I do it, because I can not have two devise on the same network. Why should not it be renamed for remote configuration?

Thank for your reply.
Pierre

SPI is enable.
Power supply is original from RPI (V2.0)
I connect the IC880a with the backplane and an raspberry pi 2.0 Version B

Could anybody help me?

Hello,
I am installing a Lora WAN gateway but before I began suddenly I found that the packet forwarder has been on hold https://github.com/TheThingsNetwork/packet_forwarder
and in the TTN-ZH I found that the install.sh will use it

Build packet forwarder

if [ ! -d packet_forwarder ]; then
git clone -b legacy https://github.com/TheThingsNetwork/packet_forwarder.git
pushd packet_forwarder
else
pushd packet_forwarder
git fetch origin
git checkout legacy
git reset --hard
fi
make
popd
so my question is that will I found a problem in sending data to TTN ?
In the link above of packet forwarder you can see that they suggest " Semtech packet forwarder or MP packet forwarder. How to use one of them instead of packet forwarder ?
Thank you in advance.

I read that using Wifi is not great due to interference with the LoRaWAN signal.

I'd like to encourage you to add in the Documentation (readme) a suggested best-practice method to disable wifi for the ttn-zh project. I've found various approaches. But this one seems like a good one to me:

add new line
dtoverlay=pi3-disable-wif
to
boot/config.txt

as described here:
https://raspberrypi.stackexchange.com/a/62522/58012
referencing:
https://github.com/raspberrypi/firmware/blob/master/boot/overlays/README

Hi there,

for TDoA (Time Difference of Arrival) triangulation for geopositioning we need very precise timestamps. Have you tried in your setup whether timestamps can be retrieved in nanoseconds instead of the default microseconds? To know that would be really great! Thanks a lot in advance!

Best wishes!

• How to create a ssh file
• always download the latest raspiban file
• use a fritz box or other hub that has dns and thus can resolve [email protected]
• add how to enter a wifi network, and one without password

since 20hours my gateway is not seen by ttn after working for 2 years now without any known errors.
Looking at syslog ist seams to work like always. no errors.
Where should I look for the error.
thomas

something like “Operational flowchart“

Due to the introduction of predictable network interface names in Debian/Raspbian Stretch the use of interface name is now changed to include the mac address. A typical example:
"enxb827eb8d8982".

Power via gpio

Are there possible safeguards that could be stated ?
Are there possible safeguards on the pcb (tindie) that could be implemented (barral connector)?

https://github.com/ttn-zh/ic880a-gateway/blob/spi/images/power-via-gpio.jpg

I don't want to forget this thought: if already thought thru: please close, otherwise tracker until sure of power.

I go and find some pi reference and may add below this line.

http://raspberrypi.stackexchange.com/questions/1617/how-do-i-supply-power-through-the-gpio

Due to a voltage interruption to my RPi the SD card with the gateway software on it crashed.
Time to make a fresh card with the latest Raspbian light software.
I have done this several times without any issue, but it is the first time with BUSTER LIGHT.

I have followed all the steps in the wiki. When I arrived at the clone step I got an error message:

start screen dump:

ttn@raspberrypi:~ $ git clone https://github.com/ttn-zh/ic880a-gateway.git ~/ic880a-gateway

Cloning into '/home/ttn/ic880a-gateway'...

/usr/lib/git-core/git-remote-https: error while loading shared libraries: er▒: cannot open shared object file: No such file or directory

ttn@raspberrypi:~ $

stop screen dump

it says:

"if you want to use the remote configuration option, please make sure you have created a JSON file named as your gateway EUI (e.g. B827EBFFFE7B80CD.json) in the Gateway Remote Config repository."

How do I do that?

I followed the instructions and when I launch start.sh I get:
./start.sh: line 43: ./poly_pkt_fwd: No such file or directory

Hi !
thank you for your Job !
I have just one probleme why I receive date every minute and not in really time
thears some configuration for fix that

Hi,

First of all, thanks for this nice work.

I have though a request to extend the installation script to ask whether the gateway will be a LoRaWAN public or private network. One more question like "Do you use LoRaWAN private network? [y/N]" in the script...
This information is in the global_config.json file in the "SX1301_conf" section as :
"lorawan_public": true,

I don't know if this information can be replaced in the local_config.json.
It took me the whole day to figure out that my system was not working reliably because my endpoints are for private network and the default values for this parameter is true ! If adding this question can save other people hours of research....

I thank you in advance,
Best regards,
OM.

Morning all,

I've spent some time trying to resolve this, and discussed on the TTN forums. I'm beginning to suspect there may be a code issue.

I did a clean install of Stretch and got the GPS module set up and working first. It's a Raspi3 so I reconfigured the serial ports to feed the NMEA to the hardware UART. Using GY-NEO6MV2 module. That gets me reliable position information on ttyAMA0:

...
$GPRMC,225036.000,A,51xx.xxxx,N,000xx.xx,W,0.00,200.38,090318,A*71
...

I then installed and configured ttn-zh per the wiki. Everything is up and running and the concentrator appears to be seeing the GPS:

...
Mar 9 22:47:09 ttn-dev-gw ttn-gateway[538]: INFO: Reference longitude is configured to 0.000000 deg
Mar 9 22:47:09 ttn-dev-gw ttn-gateway[538]: INFO: Reference altitude is configured to 0 meters
Mar 9 22:47:09 ttn-dev-gw ttn-gateway[538]: INFO: GPS is enabled
...

(I say ‘appears’… it isn’t throwing any errors about opening the serial port. I’m slightly suspicious that I can still cat /ttyAMA0 in another shell.)

However, the gps time reference is defaulting to unix epoch. It looks like perhaps an initial sync was missing:
...
Mar 9 22:49:32 ttn-dev-gw ttn-gateway[538]: ### [GPS] ###
Mar 9 22:49:32 ttn-dev-gw ttn-gateway[538]: # Invalid gps time reference (age: 1520635659 sec)
Mar 9 22:49:32 ttn-dev-gw ttn-gateway[538]: # Manual GPS coordinates: latitude 0.00000, longitude 0.00000, altitude 0 m
Mar 9 22:49:32 ttn-dev-gw ttn-gateway[538]: ##### END #####
...

Per the example above, the timestamp on each sentence format is correct. I’ve also patched the PPS output from the GPS module to pin 19 on the iC880a concentrator, although I don't think this matters.

I've had a look at poly_pkt_fwd.c and there's nothing obvious I can find, although this suggests there may be some work remaining:

            printf("### [GPS] ###\n");
            //TODO: this is not symmetrical. time can also be derived from other sources, fix
            if (gps_enabled == true) {

and:

            //TODO: is this okay, can time be recruited from the local system if gps is not working?
            /* get a copy of GPS time reference (avoid 1 mutex per packet) */
            if ((nb_pkt > 0) && (gps_active == true)) {
                    pthread_mutex_lock(&mx_timeref);
                    ref_ok = gps_ref_valid;
                    local_ref = time_reference_gps;
                    pthread_mutex_unlock(&mx_timeref);
            } else {
                    ref_ok = false;

...although by my reading that suggests alternate sources should only be used if the gps isn't working.

Thoughts?

I meet a issue that"error: pathspec 'legacy' did not match any file(s) known to git.",and I don't now how to solve it.

Please change the command while installing the packet forwarder in this link
after these two commands:
$ git clone https://github.com/ttn-zh/ic880a-gateway.git ~/ic880a-gateway
$ cd ~/ic880a-gateway

It should be: $ sudo ./install.sh spi

But it is like : $ sudo ./install.sh

spi is missing and it's confusing most of the people.

Hello All,
I have a strange behavior and I would like to know if you can help to understand.

Let me first describe how is my structure.

I have 2 nodes in a orchard at about 450m altitude. There are not above the tree and the foliage, but on the top (you we will better understand later). One of station is in the middle of the orchard and the second at the end.

The gateway it on the top of my camping car, at about 900m of the first station and about 1100m of the second.

I know that my gateway is not well located because it is at a lower altitude than my nodes and there are winyard between them.

Between June and September 2018, in general the transmission were fine.

End of April 2019, I turned on my nodes and the gateway for new measurements, while the trees did not have foliage yet and the transmission started well (the nodes transmit each hour). The leafs appeared and grew up. And suddenly, at the same time (within one hour) , the gateway do not receive and transmit the messages from the nodes.

As it happen at the same time, I though about a problem with the gateway, but not. Then I moved the gateway at about 500m from the nodes, almost at the same altitude and the area is clearer. The nodes stated to transmit again. Great!

It ran well for about 2 weeks until my Gateay MicroCard broke. I changed and reinstalled it. The nodes transmitted again but only fro 4 hours.

** nodes stop transmitting at the same time again**. Or let say may be , the gateway do not receive the message, because the nodes has not stoppred working. For me, its still transmit.

I thought again an issue with the new installed gateway, but not, the gateway worked (I can see the green status at TTN console . Then, I moved the gateway at about 50m from the nodes and the nodes started transmitting!

My guess is as the foliage “covers” the nodes (even if there are at the top of the tree), the foliage act as an obstacle, but it can not explain why the two nodes stopped transmitting at the same time, first all because the apple tree has very less foliage at the second node. My guess is the foliage would make an obstacle, the node will not stop transmitting during the same hour, but may be, with a couple of days of delay.

Then I would to understand why this behavior?
Why the node stop transmitting at the same time, and why it works when I move closer the gateway, while last year, it worked at 1km of distance.

Can it be the power of transmitting, how changed automatically?
Can it be possible that the gateway’s range (sensitivity) somehow dropped and how can I check it and fix it?

I configured as in the example: https://github.com/matthijskooijman/arduino-lmic/blob/master/examples/ttn-abp/ttn-abp.ino#L218

Note, I am using for now (but I will change to OTAA) ABP activation method.

Thank for your point of view and have a nice evening/day.
Cheers

Hi,
we are setting up a lora gateway and we followed the same steps mentioned in https://github.com/ttn-zh/ic880a-gateway. but we are unable to find complete procedure to run the gateway connected to thethings network. we will be glad to help us in resolving the issue.
Thanks in Advance!
Regards

How do I update the gateway? Can I just rerun install.sh?

Hello guys.
First I would like to say that your job is impressive! I wish I lived in Zurich. We do not have most coverage here in Lausanne and Yverdon, even if I heard that Octanis installed a gateway recently near the EPFL.

I am not a RF guy, but I work with some of them.In my opinion it should be of importance to specify in your wiki that the antenna SHOULD be a 1/2wavelength. If 1/4wavelength, the mounting instructions are missing a rock-solid copper-foil ground plane.

Once more, thumbs up for all the work you are doing!

What does this mean exactly?

Plug the iC880a (WARNING: first power plug to the wall socket, then to the gateway DC jack, and ONLY THEN USB to RPi!)

Hi, can this software be used with pure Lora (not LoraWAN) with custom protocol?

Thanks in advance

Hi,
how to limit TX power? I wish to build GW in Czech and use 12 dBi antenna.

Regarding on limitations, max transmit power is 25mW + 0.1% “on air time” in Czech, right?

Hello, as of last month I successfully connected my gateway to the network.
Since then however, I have not been able to successfully recreate this connection even though nothing has changed in the configuration.

Illustration:

The current gateway I am using is a ic880-gateway using the TTN legacy packet forwarder protocol. My gateway is (succesfully) registered using the documentation in the README.md of this repository.

You can find my remote config here

Hi Guys,

The IMST iC880a board only supports 868MHz. Is there any way to have a 915MHz implementation (legal requirements here in Australia)?

Please help. Thanks

Hey guys,
After installing the install.sh and rebooting, I wanted to check if the service was running (since it was not being shown in the console) and here is what I got:

rxhf@radek-gw2:~/ic880a-gateway $ sudo service ttn-gateway status

Hint: Some lines were ellipsized, use -l to show in full.

I get this "failed to start the concentrator" quite often in my other gateway, but after retrying a few times the gps_packet_forward it works. Should I just retry with this one as well? If so, how? By rebooting it and rechecking the status of the service over and over?

I've just received my IC880a gateway module and built it following the guide at https://github.com/ttn-zh/ic880a-gateway/wiki.

I'm running the latest Raspbian Stretch Lite build and the Pi connects by LAN cable.

The Pi is a model B2, power is povided by a 5V 2.5A usb power official power supply.

I have tripple checked all of the jumper connections and they match the pin-out from the article.

However I don't see my gateway as connected in the TTN dashboard.

I've run the following commands to try and troubleshoot the issue:-

Do you have any suggestions on what I should check?

I had issues with the gateway, so I did an update. The issue was that the gateway stopped forwarding packets after 4 days, and showed offline in the TTN backoffice.

After the update I do not receive any downlink messages anymore. In de TTN backoffice I can see in the traffic overview of the app that the downlink message is received by TTN, but no data on both of my nodes. These nodes worked fine before the update.

Uplink data seems to work fine.

Os = 9 (stretch), raspbian

Edit: I did rerun the install script, and the gateway did a reboot. Now the downlink messages are working again. I am curious however how can I troubleshoot this on the gateway if similar events occur?

Hi,
I have the RAK831 Gateway and I want to use it with my custom code and backend server, can this software be used in any way to do this?
Thanks

I am using 5V,1.6A adapter, my remote config file is pushed to the repository, I have edited the reset code into my start.sh file, my SPI is enabled as well.

#! /bin/bash

Reset iC880a PIN
SX1301_RESET_BOARD_PIN=22
echo "$SX1301_RESET_BOARD_PIN_22" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio$SX1301_RESET_BOARD_PIN_22/direction
echo "0" > /sys/class/gpio/gpio$SX1301_RESET_BOARD_PIN_22/value
sleep 0.1
echo "1" > /sys/class/gpio/gpio$SX1301_RESET_BOARD_PIN_22/value
sleep 0.1
echo "0" > /sys/class/gpio/gpio$SX1301_RESET_BOARD_PIN_22/value
sleep 0.1
echo "$SX1301_RESET_BOARD_PIN_22" > /sys/class/gpio/unexport

Test the connection, wait if needed.
After restating it, and checking the gateway status by running
sudo service ttn-gateway status

I get

Hello
I installed and configured two gateway following that procedure. Wedenesady, I stopped my gateway and when later I restated it, no way to be seen by TTN.
I have a second and same gateway and this one can be seen by TTN but now message are transmitted to TTN throught the second gateway.

Regarding the first gateway, which stop working, I moved iit to my place and I switch it on. Once again, from my flat, the gateway can not be seen by TTN.

I am planning to reinstalled it, but first there is a way (a command from Raspberry) to check the gateway (concentrator, antenna, application, etc...)?

Note that my Raspberry connected to the concentrator, starts well. I can be remotely connected to it, and I have an internet access. In spite of this, the gate way is not seen by TTN. Can it be possible that Gateway remote configuration file is corrupt?

Thank
Cheers

Hello, I am currently creating a LoRaWAN outdoor multi-channel gateway fora university project. I purchased a RPi3 B+ and an ic880A and followed the guide on https://github.com/ttn-zh/ic880a-gateway/wiki, I even added my gateway ID to the remote-config repo. However, by the end of the installation my gateway status is “not connected” on TTN. Can anyone please help out. Here are some logs from my RPi.

After running sudo systemctl status ttn-gateway.service I receive the following,

ttn@ttn-gateway:~ $ sudo systemctl status ttn-gateway.service

Any and all help will be appreciated :)

with ch2i board used to connect RasPi to ic880a RESET has different pins (namely 11@Raspi instead of 22@Raspi). How can those be changed by software?
