Other Parts Discussed in Thread: CC2540

Dear Ti:

1，I'm using TI BLE stack v1.2.1, after download programme to the board, the current is between 6-8mA, does this work normal?

2，in debug mode, can get in the code below just a few times at beginning，then can not get in again。

          else
   {
              osal_pwrmgr_powerconserve(); // Put the        processor/system into sleep
}

3，what is the lowest current when CC2540 & 4S keep in connection state？

4，when CC2540 & 4s keep in connection, if i run a task that takes long time, the connection was broken, how to avoid this?

5，can cc2540 be used to transmit files to special application write by me on 4s?

thanks a lot.

Make sure the POWER_SAVING is defined in IAR (you probably already doing this), and also as the CC debugger manual states, you can not use the debug method when trying to put the processor to sleep. Program is unpredictable in this case. best to remove the debugger and use in-line current meter to acquire a time-based average since processor is in frequent sleeps & wakeups. good luck
