cc2530 consumption

I am trying to us chip cc2530 in low power mode.

To test it I use the following code:

file "rsa_main.c":

int main(void) {

  while (true)  { halSleep(0);  };

  return 0;

}

When running this code on device and measuring cunsumption current I get 7.8mA;

However datasheet says thet it should be 4uA;

Could someone explain me this phenomen?

Thanks
