Hi,
Do you have any example of code for sending data to IoT 4.0 (cloud foundry) over MQTT?
Since there are some complication on the certificates.
thanks

When sending the response is 200 and a html code.
when entering in the website of the html code and sending the form in there, you get this:
{"msg":"Parse error. Expected [messageType] of type [string]"}

Anyway your message doesn't get stored in the database table T_IOT_HTTP_PUSH (where the pushed messages are stored until the sensor device makes a pull request) for late consumption of the sensor device.

Same as http://scn.sap.com/docs/DOC-63811#comment-590831

I set up the application as explained.
Yet, it seems the table used for storing messages (and which follows the naming conventiion T_IOT__) are not created.

Am I missing something?

Settings look OK

But no table...

Event though they do share the same schema

Thanks in advance.

Hello,

I have the problem that I get a 404 error when I want to send messages to the device. All other functions work perfectly.
Thanks for help.

Hello,
I have configured the sample.properties in the resources but it did not work.
after i debugger,i found get property's path is ~\iot\iot-starterkit\cf\samples\java-samples\ commons\target\sample.properties
but actualy,sample.properties is exist in ~\iot\iot-starterkit\cf\samples\java-samples\ send-command\target\classes\sample.properties after mvn install

cf/samples/java-samples/send-command project

Hello ine the cloud platform the destination iotrdms response is code 503 service unavailable can you help me please.

Best regards Julien.

When using the "Send message" or "Switch LED state", the application is displaying a "undefined" message.
If you look further (breakpoint in index.html in pushData function), this is due to the system being unable to log you on and requesting a SAML token.

This can be seen at this URL;

Thanks in advance.

Hello,
I tried to use the Java application but I can't select any device/message type data seen on the attached picture.

Thanks for help.

The program can potentially fail to release a system resource.

I tried consumption-advanced but failed.
enclosed the screenshots.
it looks like the accessing the iotrdms v2 api via HCP destination failed.
https://webidetesting9968994-i029837trial.dispatcher.hanatrial.ondemand.com/iotrdms/v2/api/deviceTypes
I tried
https://iotrdmsiotservices-i029837trial.hanatrial.ondemand.com/com.sap.iotservices.dms/v2/api/deviceTypes
it was successfull
can you advise ?

thanks & Best Regards,

Hello,

I would like reconstruct the Raspberry Pi example and i'm looking for the suitable components on the internet. Can you help me to get the right IoT hardware?

Hi,
I tried to use the java application on my HCP trial account.
After selecting a device and a message type, no values are displayed. Using the development tools in Firefox, I can see, that json files with data from the data base tables are received. Any Idea why this data is not displayed on the web site?
Thanks you very much,
Stefan

Hi,

The curl example for sending data for a sensor is invalid;

• the alternate ids are are sent as numeric literals not strings
• the semantics for the attribute "measures" is not clear (the values passed are non-integer).

Can you confirm this example works as intended, or point to documentation that might help?

I'm setting up for the OPC UA protocol,
i configured the protocol-config.sh file and launched the command
. ./protocol-model.sh
I get the following error (i added spaces in the html tags)

sed: -e expression #1, char 27: unterminated `s' command
< html >
  < head >
    < title >404 Not Found< /title >
  </ head >
  < body >
    < h1 >404 Not Found< /h1 >
    < p >The requested resource has not been found. < br >
    Please check the requested URL.< /p >
  < /body >
< /html >

is it possible to have support?

looking at the documentation on iot/core/api/v1/doc/
I made the following change

URL_CAPABILITIES=https://${HOST_NAME}/iot/core/api/v1/tenants/${TENANT_ID}/capabilities
URL_SENSOR_TYPES=https://${HOST_NAME}/iot/core/api/v1/tenants/${TENANT_ID}/sensorTypes

I get the following error
{"message":"Invalid client request."}

I then tried this way and it worked

URL_CAPABILITIES=https://${HOST_NAME}/iot/core/api/v1/tenants/capabilities
URL_SENSOR_TYPES=https://${HOST_NAME}/iot/core/api/v1/tenants/sensorTypes

Hi all,

i just tried out the above menbtioned python script.
but in this line:

client.tls_set(config_crt_4_landscape, certfile=config_credentials_crt, keyfile=config_credentials_key)

I got this result:

Traceback (most recent call last):
  File "commands_and_heartbeat.py", line 101, in <module>
    client.connect(broker, broker_port, 60)
  File "E:\python363\lib\site-packages\paho\mqtt\client.py", line 768, in connect
    return self.reconnect()
  File "E:\python363\lib\site-packages\paho\mqtt\client.py", line 927, in reconnect

    self._sslobj.do_handshake()
ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)

If i change the line to:

client.tls_set(ca_certs=None ,certfile=config_credentials_crt, keyfile=config_credentials_key)

it works:
(0, 2)
Connected to MQTT broker with result code: 0
on_subscribe - message_id: 1 / qos: (0,)

the provided iot service cert "config_crt_4_landscape" is attached (pls change to '*.crt'):

Since the last update, the readme (for java app) no longer explains where you need to add your own message type, device type, ... to the index.html. This info is however key in getting the iot starter kit working.

Hello,

I write the same issues/question in the general GitHub "Issues" yesterday but that wasn't the right place. If this the wrong channel again please tell me where is the right place.

My Question: I would like reconstruct the Raspberry Pi example and i'm looking for the suitable components on the internet. Can you help me to get the right IoT hardware?

Hello,
I'm failed to use the Code-Snippets insert.py to send a message from a real IoT-Device to the SAP HANA Cloud Plattform. I can successfully test the HTTP API in the MMS with the same device, but when i use the insert.py i get the Error message "Access to the requested resource is not authorized (HTTP 401).".

What can i do to solve this problem?

thanks & Best Regards,
Pit

Hi all,

the links to the offical SAP Help Doku are broken (points to the old SAP Help url), i think ist heplpful to have the correct one referenced.

Hi,

I deployed Java consumption application as described in below link [1]
[1] https://github.com/SAP/iot-starterkit/tree/master/neo/apps/java/consumption

Using the Message Management Service (MMS) Cockpit I can send messages to a message management service and I can see the stored messages, using "Display stored messages" in the MMS Cockpit (for different devices and different message types).
After deploying and starting the iotstarterkit application I can access the application but I get blank for all the lists.

I have made below checks before posting here:

1. "starterkit" java app is bound to the same schema ID as "iotmms". They both have a binding pointing to same schema(iotmmsschema) ID.
2. Destinations section of "starterkit" app.
   "iotrdms" destination URL is
   https://iotrdmsiotservices-pxxxxtrial.hanatrial.ondemand.com/com.sap.iotservices.dms (with trial suffix), User is (with no trial suffix) and Password is my SAP Cloud platform login password.
3. Destination section of "starterkit" app.
   For "iotmms" destination:
   URL is https://iotmmspxxxxtrial.hanatrial.ondemand.com/com.sap.iotservices.mms (with trial suffix), User is (with no trial suffix) and Password is my SAP Cloud platform login password.
4. In browser on executing below link, I get following devices.
   https://iotrdmsiotservices-pXXXXtrial.hanatrial.ondemand.com/com.sap.iotservices.dms/v1/api/devices
   [{"id":"5b6b0dc6-f5b9-4232-8bfc-10add9a295cd","name":"MyGrovePI","device_type":"90b08720c75d218ef422"}]
5. I created device types, message types and devices via the IoT Services Cockpit (see below picture).
   

Can someone help me, what might be the problem?

Regards,
Harsha MP

I think it would be worth mentioning that the user in encoded credentials should be [user]#[tenant]:[password]

Hi,

I try to send command from cloud to the gateway but the api for command gives me an error.(even get is not working)

I guess I don't have the command feature installed on the IoT 4.0 service... is that the case?
