Today I tried to run the redSensorToCloud example on my mangOH red. I followed all the directions and was able to succesfully compile and load the app on the target: my mangOH red board + WP7607-1.
Unfortunately when I try to start the app I receive the following error:

I have seen the same problem raised here: Error starting redSensorToCloud [Solved]
I tried the solution proposed by dfrey. Unfortunately, this did not seem to solve my problem. Since I’m out of ideas at this point I would appreciate it if someone could help me, since it is blocking me from continuing development.
For your convenience, I have added some more information:
A painful process I know - but perhaps it’s worth re-running through the build process (effectively a full rebuild) with a careful eye on current/correct/matching versions and on any faults thrown during any of the intermediary steps. (I have personally not encountered this issue).
I would recommend a full rebuild - ensuring you have the most recent versions/releases.
While I did not encounter your issue I had others and this process resolved them for me.
I rebuilt using the latest, Legato Distro 18.10.3 and for me the WP77xx and double-checking all matching versions. Carefully eyeballing the output of every build/make/compile step to ensure no errors were thrown that I had missed before moving on to the next step.
I will try that, thanks for the suggestion. Any advice on how to make sure I have the most recent versions / releases of everything? I am new to linux and legato has been quite the learningcurve to say the least.
Other thing to notice, it has only been this specific app that has been causing issues. All the other examples seem to run fine. I am just really worried that if I can not fix this error it will become a problem in a later stage of development.
If anyone is still having this issue, please try with the latest release for your module and the associated toolchain. Then build against Legato 19.01. If that doesn’t work, post the full output of dmesg after a reboot has completed.
Hello
I´m executing RedSensorToCloud with firmware version in the module 2.16 and Legato Framework 18.09 but application stops .
In the pass I have run this application without problems but with a previous Legato Framework. 18.05
This is the error I have related with the led service. May 23 08:54:17 | supervisor[783]/supervisor T=main | app.c CreateFileLink() 1507 | Could not stat file at ‘/sys/devices/platform/led.0/led’. No such file or directory May 23 08:54:17 | supervisor[783]/supervisor T=main | app.c CreateFileLink() 1624 | Failed to create link at ‘/sys/devices/platform/led.0/led’ in app ‘redSensorToCloud’. May 23 08:54:17 | supervisor[783]/supervisor T=main | app.c app_Start() 2954 | Failed to set Smack rules or set up app area.
I have add the LedService by pointing the directory
Right click on the API’s directory under the new project.
Add the LedService by pointing the directory.
When I dowload the application to the module WP7702 I receive the message that "Legato Framework version used in application 18.09.01 and running on the devices 18.06.1 are not the same. "
In SierraWirless source latest firmware version for the module I have is 2.16

I have update rebuild the system with the latest version but the result is the same .
I have “RedSensorToCloud” already runnig but building the application with commands. It generates the file " mangoOH.wp77xx.update"
This application has dependencies with “LedService”, “DataHub” and “Battery”. When downloading the application in the WP7702 appears these application running.
There should be some documentation about that. Before “RedSensortoCloud” didn´t have these dependencies.
When trying to complile using developer Studio updating the Developer estudio to Legato Frameworks 18.09 I have follow these indications
I generate all the files without issue but they don´t run OK . File “mangoOH.wp77xx.update” generate by developer studio only generate the “Datahub” when is downloading on the modules. Then I have add “Led Service” and “BatterY” but application does not run anyway. I doný know why.
When creating the project I import the Project from a existing code and then I browse from mangoh/MangoOH.
Previously I have configuree the DS environment for MangOH projects.
In the Window > Preferences > C/C++ > Build > Environment , add:
a MANGOH_ROOT variable pointing to the MangOH clone (i.e. /home/mangoh/mangOH )
a MANGOH_BOARD variable equals to the board you’re targeting (either RED or GREEN ).
I would like to run the samples with “Developer Studio” and changes on the basics application and dependencies should be documented.
I have also add the new app dependencies defined in sdef file of MangOH.sdef adding the appropriate paths in the project properties > C/C++ build > Settings dialog, in Interfaces or Dependencies sections but still i have the same problem. I ´m still missing something.
