Question:
Fiware iotagent: How to send measure from a device?

Description:
I'm developing a Fiware system and I don't know how to send measures from a device through IDAS iot-agent.

I have Orion and Cygnus running, but I'm sending the measures with a servlet directly to Orion and I want to switch the proccess to IDAS iot-agent.

I've created the service and the device properly but I'm stucked with the POST from the device to the iot-agent.

My device is created as follows:

{ "device_id" : "0010", "entity_name" : "0010", "entity_type" :
"xxxxx", "timezone" : "Europe/Madrid", "attributes" : [

], "service" : "xxxxx", "service_path" : "/xxxxx" }

How it would be the POST from the device to send the measures?

Thanks.

EDIT:

I tried to POST from a command line to test like this:

curl -X POST xxxxxxxxxxxx:8080/iot/d?i=0010 \
-i \
-H "Content-Type: application/text" \
-H "Fiware-Service: xxxxxx" \
-H "Fiware-ServicePath: /xxxxxx" \
-d "s_temp|25"

And here is the response:

HTTP/1.1 415 Connection: close
Content-Length: 88

Now the question is... if I had installed iot-agent-base and iot-agent-ul, Why I'm not able to POST text? Did I miss some configuration?

EDIT:

I'm able to send values to this url:

http://xxxxxxxx:8080/iot/xx?k=xxxxxxx&i=xxxxxxxx#fecha|1#coord_x|1#coord_y|1#coderr|1#s_temp|1#s_hum|1#s_temp|1#num_sat|1#voltaje|1#inicio|1

And this is the respone

DEBUG - Accept: /
DEBUG - End filters status 200
DEBUG - Proccessing in handle /iot
DEBUG - iota::AdminService::error_response 0
DEBUG - finish connection 2
DEBUG - Get statistics /iot/ngsi Counters 0
INFO - Agent Activity {"statistics":[

]}

But Orion doesn't get anything

EDIT:

It was a version issue, now I have the latest version of iot-agent installed with UltraLight module and device with "protocol":"PDI-IoTA-UltraLight" and the protocol itself is working.

But I don't know what is the correct url to post measures from the device. Any help?
