uart in the sensordemo project

Other Parts Discussed in Thread: CC2530

hello everyone:

      I am studying the sensordemo project from the zStack-cc2530-2.3.0-1.4.0 in the IAR7.51a environment. In my project, I add the UART function in the SensorEB-PRO,and  I set my report event ( osal_set_event( sapi_TaskID, MY_REPORT_EVT )  ) in the UART callback function (  uartRxCB(uint8 port, uint8 event) ). The CC2530 chip have to read data from a kind of Temperature chip by the UART ISR,and sent a byte data to the coordinator  in every  minute.

    But the problem is that :I set breakpoints in the uartRxCB (uint8 port, uint8 event) . when I only run the sensor node and debug the code by single-step ,the CC2530 can read the UART data .BUt when the sensor node join the network created by the coordinator,the code can not through the breakpoints ,and the sensor node  can not send data to the coordinator node.

Thank you!
