Setup note for Sigfox – SAP Cloud Platform Internet of Things Cloud Foundry Environment —
Introducing
This is a note when I set up SAP Cloud Platform Internet of Things Cloud Foundry Environment and Sigfox. This is the place where the customer misunderstood when setting up. I think this is useful information and I will publish it.
Java virtual machine
This is a problem you may encounter if you build the “Internet of Things Edge Platform” on Windows. Be sure to use the 64-bit version JVM. In the 32-bit version, even if the hardware has sufficient memory, you cannot start because of a heap memory problem.
config_gateway_rest.xml
Unfortunately, the “config_gateway_rest.xml” file output by “build rest-sigfox” command is difficult to understand.
I prepared a template to make the settings more understandable.
First , please login to your IoT Service cockpit , then move to your tenant.
Then , please memo of URL. maybe this URL is like following.Then, replace the <HOSTNAME>,<INSTANCENAME>,<TENANTNAME> part in the XML below with the following.
<HOSTNAME> to xxxxxxx-xxxx-xxxxx-xxxx-xxxxxx.xxxx.cp.iot.sap
<INSTANCENAME> to yyyyy-yyyyyy-yyyyyy-yyyyyy-yyyyyyyyy
<TENANTNAME> to zzzzzzzzzz
Sigfox user and password
The user ID and password specified in <cnf:apiUsername> and <cnf:apiPassword> are NOT the ones used when logging in to Sigfox portal (https://backend.sigfox.com).
You must generate this user ID and password on Sigfox portal.
Then, Click ‘API Access’ of left side .
If you don’t use API ACEESS feature , click ‘New’ button.
Please fill in the API Access information box. Name is free.
OK, User id and password are generated . You should use these values for <cnf:apiUsername> and <cnf:apiPassword>.gatewayAlternateId
The number 1122334455667788 is used in the manual, but it is better to make it easy to understand.
Template of config_gateway_rest.xml
OK , you can prepare the value of <HOSTNAME>,<INSTANCENAME>,<TENANTNAME>,<SIGFOXAPIUSER>,<SIGFOXAPIPASSWORD>,<GATEWAYALTERNATEID>.
Let’s replace these with the XML below and use it as config_gateway_rest.xml .
