Running an LED blinking program on cc2530
Based on my vast experience, I think you are not blinking the LED. Change second  LED1_PIN = 1; toLED1_PIN = 0; and wait for some time.

Edit: The waiting time after the LED has turned off is so less to perceive it as off by the human eye. As @peter pointed, the delay can be made equal and huge between both turn on and turn off code segments. Congrats 
! You got your code working.
