Here are my steps to configure IoT Agent UL (1.12.0-next): git clone https://github.com/telefonicaid/iotagent-ul.git cd iotagent-ul/ npm install cp config.js config-ul.js Change params in config-ul.js if you need node bin/iotagent-ul config-ul.js

As I know, you have to use an MQTT server as described in the doc (https://fiware-iotagent-json.readthedocs.io/en/latest/stepbystep/index.html). But if you want to send data directly to IoT Agent via HTTP, try to use IoT Agent UL (https://github.com/telefonicaid/iotagent-ul)

Singular notifications (/v2/entities/Car1/attrs/speed and /v2/entities/Car2/attrs/speed) are fine. Of course, I'm using the same headers (for all). But only the first entity (Car1) will be notified if I change the speed attribute for both, using /v2/op/update API.

Hi all, I created multiple notifications using idPattern (Car[1-5]) to sent notifications for any Cars of the same type to save data using Cygnus. Subscriptions works! I can update any attribute (i.e. /v2/entities/Car1/attrs/speed). But can I use a batch operation (v2/op/update) to update multiple attrs? I tried but only one (first) attribute will be notified (and stored) If yes, what can I do it? I also tried to configure CYGNUSMYSQLBATCH_xxx params but without success. Thank you pasquy

Hi all, I'm using Orion Context Broker to display public context information. I would like to login on my application to add subscriptions with a specific user roles; for example users belongs to roleA can see only subscriptions for that roleA, and users belongs to roleB only subscription for roleB, ect.... Is it possible?

I think you have to install IoTAgent (i.e IoTAgentUL) on your PC and configure it in mqtt mode. Raspberry is the publisher and IoTAgent the subscriber. After configuring and provisioning you can see your data into Orion. Use the Orion's REST APIs to get all measures for displaying.I hope I help you.

I solved my issue: I must use multiservice option in the command line when I start orion as described in the doc (https://fiware-orion.readthedocs.io/e...): $ contextBroker -multiservice

My context is public, I've a select box to select fiware-service and fiware-servicepath. For all entities all users can add subscriptions. My problem is this; we want to display all subscriptions related to roles, so I need to filter the subscriptions by roles.

The only difference is the version of mongo. I'm using 4.0.9 for Orion 2.2.0, instead Orion 2.0.0next uses 3.6.9

Yes, I'm using show databases command and also a mongo client to connect on mongo instance (after open port). In my 2.2.0 instance I can see only after '> show databases': admin 0.000GB config 0.000GB local 0.000GB orion 0.000GB

Yes, you are right, but I tried with a Orion VM in FIWARE Lab (1.3.0 and 2.0.0next) and both Orion stored data in to orion-vehicles collections. I installed manually Orion 2.2.0 on Centos 7 and I have only collection: orion, with fiware-service: vehicles. Probably it's my fault in the installation.

Hi all, I'm using Orion Context Broker 2.2.0 and I'm using fiware-service and fiware-servicepath to separate the data, but I've the same results with or without the fiware-service. Is it my fault or not?

Dear all, I cannot use the POST call to http://cloud.lab.fiware.org:4730/v2.0... with payload:

{"auth": {"passwordCredentials": {"username":"my-email@email.com", "password":"yourpassword"}, "tenantId": "a121dfc9d22347ebb07eb89cc3c0e79f" } }

to get the token for Object Storage. Please, could you tell me how can I solve it? Thanks a lot Regards Pasquale

Hi, Orion doesn't store own context. This policy is right, because if your context is composed by many attributes, and you update it, any second ... after few days (for example) the internal database (mongo) of Orion will became full and your service will fault.

To store the context you can use the Cygnus adapter and you can chose, for your app, the right storage system (ex. mongo, mysql, ckan, cosmos big data, etc...) that it depends how much data you want to manage.

I'm using IoT Agent and I'm reading that there are two types of provisioning: provisioning and autoprovisioning (or preprovisioning). I tried the "provisioning" simply using the curl command (i.e. curl localhost:4041/iot/devices ...) but I don't understand preprovisioning. Are there differents or are they the same? If not, could you give me some info or real example?

Thanks a lot

Ciao Simona, I guess that you want to try the B scenario of the tutorial (https://www.fiware.org/tag/raspberry-pi/). So you edited the Register4IN1, RegisterDOOR and Register_SWITCH files (replaced all 'HACKSANTANDER' strings in the files) and in the Step 3.2 when you run:

./registerDevice 0001 4IN1

you have to expect a "200 OK response" after "M2M Platform reply". First, can you set to "DEBUG = 4" in the config file? Pasquale
