Import the received data of my gateway.

[Perico]

Hi all!
I have a temperature sensor connected with my gateway and I’m receiving the data. As I checked the data is stored at my gateway: /var/config/lora/lora-network-server.db
Now my intention is to import this data in a file or similar, but I’ve tried it with python, java and others and I’m not able to have permisions to obtain this data. Somebody knows how I can get it? I need it to deal with the data in real time.

 

*http://www.multitech.net/developer/software/lora/lora-network-server/ I’m trying to obtain as a json format looking this web, but the command it doesn’t works.

Can you share an example of the command you are trying to use?

Realtime data can be obtained with an MQTT client application.

See an example here.

I’ll take a look on it but my intention is to do it simpler, I thought I only need to be able to have acces in the database archive and with this I can export the data.

How is that more simple than direct json data as requested?

/var/run/lora/lora-network-server.db is the active file. /var/config/lora is a periodic backup.

About your first question I used the lora-query json comand and it doesn’t works, first I think that with this I can get the data, but it seems to be wrong. This folliwing the webpage: http://www.multitech.net/developer/software/lora/lora-network-server/

I can’t answer your last question, honestly I’m a bit lost in all of this. For the moment I’m working on your proposal with MQTT.

Thanks Jason.

These commands are used by the UI to get the list of packets received.

$ lora-query -x packet list json

$ lora-query -x packet up json

What results are you see to make you say it does not work?

The mosquitto_pub and mosquitto_sub commands are helpful when working with MQTT.

$ mosquitto_sub -v -t lora/#

$ moquitto_pub -t lora/0011223344556677/down -m {“data”:”AQ==”}

Dear Jason,
My problem was that I put wrong the commands:
$ lora-query -x packet list json
$ lora-query -x packet up json

Now I’ve seen that the data that appears with this comands is not instantaneously,somebody knows the actualization period time? Neverthless it’s usefull for me but now I need to see the data at real time, I’m going to try it with node-red, saving the instantaneous data in a file.
