IOT Tutorial: Send Data with MQTT

Hello @iwonahahn,

I started your Tutorial group for getting started with SAP IOT Services.

First problems appeared when i tried to install the paho client (MAC) for MQTT messaging. I tried to launch the app via package content as suggested in the tutorial. The app opens, but i can't click anywhere in the app. Everything is disabled.

STEP 6:
https://developers.sap.com/tutorials/iot-cf-send-data-mqtt.html

So I tried to build the MQTT Connection via MQTT.fx. I still can't get a connection.
The interface for the connection settings must be different to the paho client.

1) Enable SSL: I have several options for the keystore settings. We tried each option with different settings but nothin really worked. I'd like to know which option is the one i need and what i have to fill in the fields.

1.1) CA Certificate Keystore

1.2) Self signed certificates in keystores

Do i have to fill in the changeit password in the trusted keystore field?

1.3) Self signed certificates

2) What Broker Adress do I have to choose when not using PAHO ? The format ssl://<HOST_NAME>:8883 → ssl://demo.eu10.cp.iot.sap:8883 ist not accepted.

3) What about the user credentials? I tried solving the problem with entering my credentials for my root user.

4. I'd be really grateful if you could help me with either solving the PAHO problem or customizing the requirements for my MQTT.fx client.

Thank you very much.

Hi,

1. You need the certificate from 1.2.
2. The tutorial is working as it is published now, we test it for each bi-weekly release.
3. You do not need to add the User Name and Password.

Best regards,
Iwona
