First line contains template version. In this case it is „rut955-v0.01“.
When template is updated, version must be updated aswell, otherwise device will use non-updated template version.
The following lines contains requests starting with a number „10“ and responses - starting with a number „11“. Now explanation of request:
Type - 10
Code - 101
Method - POST
URL - /inventory/managedObjects
Content Type - application/json
Accept - application/json
Placeholder - %%
Params - STRING STRING
Template - JSON
Type – requests are identified by a number 10
Code – request code number, each request must contain unique number
Method – HTTP method of request
URL – URL that will be used in request
Content Type – it is Content-Type header field value
Accept – it is Accept header field value, mostly equal to Content Type
Placeholder - string which will be replaced in URL or Template JSON
Params – what kind of params are replaced, JSON template contains two strings
Template – JSON template which will be sent
Explanation of response:
Type - 11
Code - 502
Cond - <none>
Value 1 - $.c8y_Restart
Value 2 - $.id
Value3 - $.deviceId
Type – responses are identified by a number 11
Code – response code, each response must contain unique number
Cond – JSON path base pointing to an object or object list from which values are
extracted
Value… - JSON values

Now explanation of logic inside lua script. By default, example application’s lua script location is „/usr/bin/lua/cm“. Application will scan this folder for any *.lua files and load them if they contains „init“ function. Script’s „stream.lua“ content:
By using „c8y:send“ function, first string contains request code, which was defined in the template, earlier. Then comma must appear after each value. The above line shows how we update device name and device type with our own.
For more information about Lua API, download Cumulocity C++ SDK: https://bitbucket.org/m2m/cumulocity-sdk-c/downloads and look up inside „sdk/doc/lua.html“ with a browser.
