Get User Messages on the Host PC from WSN Nodes

Hi,
   I have read the "LabVIEW Wireless Sensor Network (WSN) Pioneer - Under the Hood" and try to transmit user messages from a WSN node to the host. 

However, I am stuck at the WSN Get New Messages VI. I am unable to use a "Display Message to User" function or "Unbundle function" to retrieve the messages from WSN Get New Messages VI. Can anyone help me ? I have been stuck here for hours. Thank you very much !

 

Regards,

Xinke

Hi xinke,

 

looking at your code, I believe the issu eis that the output of the Get New Message node is an array of clusters and as such should be indexed as with a normal array before being split up with unbundle. i have attached a VI that shows this to my post.

 

I hope that this helps!

Thank you for your assistance ! 

 

But I am unable to try it out as I encounter a new error "LabVIEW:  Invalid entry in configuration file.".

 

Can you assist ? Thank you.

Hi xinke,

 

This seems a rare occurence, the only time of which I can find the problem was solved by opening the project in LabVIEW 2009 before re-opening in LabVIEW 2010. I don't know if this was a solution or simply a symptom.

 

Let me know if this helps,

Hi Liam,

 

   I had Labview 2009 installed on my laptop. I have since uninstalled it and installed Labview 2010. I opened a new project in Labview 2010 with a new VI, insert the A01 input from the Analog node and hit "Run" and the error message "LabVIEW:  Invalid entry in configuration file." appears again!

 

   Can you advise what should I do ? Is there a way I can view the configuration file ? Please advise. thank you.

 

Regards,

xinke

Just an update - I have managed to resolve the issue after doing a firmware upgrade.
