Mango with WP7603 redSensorToCloud won't start


#1

Am heading through the MangOH Getting Started document and all is going well until I try to start the redSensorToCloud app to verify data is getting to AirVantage.

root@swi-mdm9x28:~# app start redSensorToCloud
There was an error.  Application 'redSensorToCloud' could not be started.
Check the system log for error messages.

Looking at the system log I see the following:

I think the root cause is due the LED file not being found. Is there a step in building the environment I need to re-do?
