Fiware Ultralight 2.0 IoTAgent: How to send measure from a device?

I am working on a POC to create Smart City IoT project using Fiware platform. I am trying to run end to end flow. I have following Docker containers running.

CONTAINER ID PORTS NAMES

24f036202f78 0.0.0.0:4041->4041/tcp, 0.0.0.0:7896->7896/tcp fiware_iotagent_1

81e16c78312e 0.0.0.0:1026->1026/tcp fiware_orion_1

bf699e1acdd3 0.0.0.0:1883->1883/tcp fiware_mosquitto_1

bfc256deddd0 0.0.0.0:27017->27017/tcp fiware_mongo_1

I am using following tutorials.

http://fiwaretourguide.readthedocs.io/en/latest/connection-to-the-internet-of-things/how-to-read-measures-captured-from-iot-devices/

I am able to create Service and devices. (data is given below).

Now, when I am sending measurement it is not working.

Please guide me what am I doing wrong? And if possible provide reference having step by step example to run end to end IoT testing.

I just followed "Fiware Tour Guide" from http://fiwaretourguide.readthedocs.io/en/latest/fiware-tour-guide-application-a-tutorial-on-how-to-integrate-the-main-fiware-ges/introduction/ and everything seems working fine.

I was using port 4041 instead of port 7896. Below request is working fine.
