App for sending data over uart (Roadrunner)

[Bjarne33]

Hello,

I want to write an application that sends the positioning data from the roadrunner to my arduino by using uart2. I was able to print the data in the console of the cfclient. But whenever I initialize and test the uart connection, I can't connect to the cfclient anymore.
This is the current code of the main function. Why can't I connect to the cfclient, when I test the uart initialization?

Thank you for your help!
Best regards,
Bjarne

update:
seems like the system wasn't ready. I added systemWaitStar() and now it works.

Great that is worked out!

systemWaitStar() is blocking until all sub systems have started and it is a good practice to use it in apps.
