I have a simple code for testing the Serial port usage. I swear I tried the exact code earlier and it functioned properly. So either I'm going blind or there is some other Issue I can't put my finger on.
Any suggestions?
Thanks
John
//Print/Write test to CC2530 as UART (38400)

I get the following errors:
