Mango M2M questions

kotoor — GMT

Hi,

I have the following questions related to Mango M2M solution.

1) The link here lists many of the Mango M2M application http://mango.serotoninsoftware.com/home.jsp (Building mgmt, health care etc). Please let us know whether any of these applications are already included in the Mango 1.12.3 ? If yes, which are the M2M servier side applications that are included with the release ?.

2) The forum discussions indicate that many users have customized Mango for supporting new applications. Which are the modules to be typically customized for supporting a new M2M application ?.

3) For a quick demo purpose, we would like to use Mango for only the M2M web application and use another M2M Service delivery platform to manage the M2M device, provision it, configure the sensor and receive sensor values. The mango framework we would like to use for business analytics, graph plotting, generating reports, events etc. I browsed through the Mango code and it has a data receiver/source component. So, if we write a bridge module that converts messages between Mango format to hte format of the other Service deliver platform and vice-versa, will it work ?. Can you provide your thoughts ?.

4) What are the list of messages exchanged between Mango (M2M server side application) and the M2M device in a M2M use case (e.g. configure sensors, read the values, getting the current status, activate the device etc). Is there any document/source file that we can look at to understand the detailed list of messages and interface.

Thanks,
kotoor

M2M v1.13.0 - Meta Data Source Bug? [SOLVED]

rcopeland — GMT

Hi All,

I just upgraded to 1.13, however I am having problems with meta data sources. I keep getting the error message: [quote]Could not convert result "sun.org.mozilla.javascript.internal.InterpretedFunction@47869d" to Numeric[/quote] for all meta data sources. Even if my meta data source only contains the code [code]return 123;[/code] which should definately work... this is why I am wondering if a bug slipped into this release. Anyone else have this same issue?

HTTP RETRIEVER: REGULAR EXPRESSION

We want to use regular expression to retrive a data from a web page.

The data is in a table and not inside a text,

Html format of the data is:

POTENZA ATTIVA CEDUTA:	1533	kW
ENERGIA ATTIVA CEDUTA:	7739700	kWh

The data we want to retrieve is 1553 in one variable and 7739700 in another variable.

Thanks for help

Serotonin Pesistent TCP Publisher/Datasource

femtom — GMT

I am trying to use this combination to exchange data among mango instances.

HTTP Sender/Receiver combination works very well, but this persistent connection does not work for me.

Could anyone tell me how to configure it? Is there any specific port to be used?

There is no much documentation about it.

Thanks

Thanks in advance!

http data source

jordan001 — GMT

Dear mlohbihler

receiving and sending data by mango, many people suggeste to use HTTP receiver data source, but it can only receive data but send data. In publisher web, it said sending data to specified data source can be set, so I want to know if these two can act together to the same data source(HTTP receiver/sender).
Program is urgent, looking forward to your kindly reply. Thanks a lot! :)

Mango not being supported? Future?

mhradom — GMT

I have not been on the forum for a while - been busy with other things and my Mango installation is doing what it needs to do. I saw the "note to visitors" on the main page [url]http://mango.serotoninsoftware.com/[/url] and wonder what that really means to the current installed base? I realize I am a nonpaying customer and Matthew needs to put bread in his kids mouth (assuming he has kids) so I fully understand if this is a financial decision.

Is my currently running installation going to go "poof" when I upgrade some part of my OS or JDK?
