Packet forwarder problem #54

Closed yassinechamekh closed 5 years ago

yassinechamekh commented 5 years ago

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. Yassine

gonzalocasas commented 5 years ago

@yassinechamekh this is correct; the development of the packet forwarded was put on hold, but it is still one of the projects that is most commonly used on gateways. MP is a valid alternative as well. Only recently Semtech published a new packet forwarder and we might switch to it in the future.

I will close this issue now, because there's no action to be taken, but feel free to keep commenting on it.

yassinechamekh commented 5 years ago

@gonzalocasas Thank you for your reply. So there is no harm using packet forwarded ? it will run normally ?

gonzalocasas commented 5 years ago

Yes, it will run normally :)

yassinechamekh commented 5 years ago

Good morning Gonzalo, I have a question, I want to add a python code to the raspberry of gateway which have this purpose :

Hi! No, that's not the best way to achieve this. The payload of the packets is encrypted and you don't have the keys at the gateway level. Additionally you don't want to tie the monitoring of one sensor to one gateway, because if you move the sensor or change gateway, the sensor will still be working but your monitor will show as it if is not.

You should instead monitor this from API/backend side. The easiest would be to setup Grafana on any server, and monitor the output of your sensor (maybe create a minimal HTTP endpoint or use a little script that gets the data from MQTT and pushes it into a database). The alerting part is already in grafana so you don't have to do anything special

yassinechamekh commented 5 years ago

Thank you for your reply, But I want the alert part before monitoring anything, so I only have to make an alert at the monitoring part if I did not receive anything send me and email or something else, is it possible on Grafana ? I did not use it before I used cayenne myedevices.

Yes, absolutely. Grafana has all that and it's very easy to configure. Also, alerting can be much more than just email, you can send the alerts to s different medium, e.g. slack channels.

yassinechamekh commented 5 years ago

Thank you a lot Gonzalo, yes I find what you mean, it is easy. One last question please, there is a way to store my data from TTN to MYSQL ?

There are lots of options to get the data into MySQL. You can check out this option using NodeRED or this simpler one using mostly just Javascript, or this other option. It all comes down to a very simple script that subscribes to MQTT and then pushes it to a database, it's literally not more than 30 lines of code in most languages.

yassinechamekh commented 5 years ago

good morning Gonzalo, Please I have a question. In fact I wrote a code in the " payloads formats " of TTN exactly in the decoder. function Decoder(bytes, port) { var humidity =bytes [0]+bytes[1]/100; var temperature =bytes [2]+bytes[3]/100; return { humidty : humidity, temperature : temperature } }

==> it work fine all what I want to know is it coded in what language ( C, C++, java, ...) ? Thank you.

It's a subset of JavaScript, executed by a Go-lang interpreter.

yassinechamekh commented 5 years ago

Good morning Gonzalo, So in my project I am almost done, I am coding the node in Arduino, I want to know if the TTN library in Arduino does it support the " Dragino Lora shield" ? Thank you.

No, it does not. If you go to the website, the hardware support is listed right on top and it says it only supports the Microchip RN2xxx modules: https://github.com/TheThingsNetwork/arduino-device-lib

yassinechamekh commented 5 years ago

Thank you for your fast reply. yes I saw that I thought that they added it in the last update, do you know a library that support Dragino lora shield ?

LMiC should do the trick: https://github.com/matthijskooijman/arduino-lmic/

yassinechamekh commented 5 years ago

Hello gonzalo, So everything work fine, I only now want to see the my data in Node RED. I did everything like the The things network said https://www.thethingsnetwork.org/docs/applications/nodered/quick-start.html but it doesn't work, it always gave me error ( I put everything write ) . Do you have any idea please ? Thank you.

@yassinechamekh I don't know, sorry. Best would be to post your question on the TTN forum.

yassinechamekh commented 5 years ago

Good morning Gonzalo , Please I have a problem could you check it with me I can't find the problem ( the compilation is good but there is warning and in ttn I can't receive the payload that I want ) . You will find the Arduino code in the attachment and the warnings. The code in Arduino you can compile if you want it will be easy for you. Thank you in advance.

@yassinechamekh attachments don't get attached to the github issue, so I don't see the code you mention, but on the other hand, this is not the right place to ask for help on arduino code, this repo is for the ic880a gateway installer stuff. Please, as I already mentioned, post your questions on the forum.

yassinechamekh commented 5 years ago

Good morning GONZALO, In fact I follow the steps that you made in GitHub for https://github.com/ttn-zh/ic880a-gateway#the-things-network-ic880a-based-gatewayThe Things Network: iC880a-based gateway but the gateway it disconnect a lot of times in one day, do you have an idea ? And one last question , I see that there is the packet forwarder in the repository , should I follow the steps there and install it or does it already installed when I followed the steps in ic880a gateway ( I mean in install.sh) ? Thank you.

Yes, disconnects are not uncommon if you used jumper wires to connect the board, although they are not very problematic because the packet forwarder will restart automatically. But as you can see in the instructions, it's strongly recommended that you used a pcb board to interface the two, instead of the jumper wires: image

In the instructions you will find the links to the different options, or you can print your own PCB if that's your thing.

Regarding your other question, the packet forwarder is installed already as part of the steps in the install.sh.

yassinechamekh commented 5 years ago

Yes I am already using the backplane ( coredump) for ic880a with a raspberry 3B+ . But I saw that the packet forwarder has been updated 2 years ago ( https://github.com/TheThingsNetwork/lora_gateway#v401v4.0.1) ; https://github.com/TheThingsNetwork/lora_gateway ( link in install.sh) but in my case the https://github.com/TheThingsNetwork/lora_gateway#v301v3.0.1 ! I tried to reinstall the install.sh , I said maybe it will update it but nothing happen , I don't why I am stuck at that particular version and I don't get updates.

That's the correct version, the installer installs the legacy branch.
