RTOS/CC2650: stack size error in cc2650 launcpad

Part Number: CC2650

Tool/software: TI-RTOS

Hi,

I am using cc2650 launchpad for development, in that i used simple_peripheral as example.  everything worked fine but when i included blink led operation in this example, code get complied but over the launch board led blink operation does not perform well. 

I included led blink function in SimpleBLEPeripheral_taskFxn() in for(;;) loop, when i perform this code led blink for 2-3 time after that it does not blink. So i changed task stack size(3024) as well as run time stack size(2024) also(took random values- i tried with low values first), but for every value of combinations same kind of output seen.

code format:

==========

static void SimpleBLEPeripheral_taskFxn(UArg a0, UArg a1)
{
// Initialize application
SimpleBLEPeripheral_init();

// Application main loop
for (;;)
{

doWork();

CPUdelay(24e6);     .........................................

//Led_Blink Function

void doWork(void)
{

PIN_setOutputValue(ledPinHandle, Board_LED0, 1);
CPUdelay(24e6);
PIN_setOutputValue(ledPinHandle, Board_LED0, 0);

}

Is there any kind of stack overflow problem or something else?

2) after hit scan key in BLE_Device _Monitor i am able to see simple peripheral in device list but when i hit connect key that time i get following error-

GAP Link Established : Status=18 h=0000

& this error comes with all provided examples in sdk (ble_sdk_2_02_01_18).

what kind of error is this?

Thank you.

    Hi Gaurav,

    This problem appears for all projects after you attempted to add the red led functionality to a single example? This is definitely odd if this is the case.

    Please start fresh - uninstall SDK and reinstall. Verify that simple_peripheral works. Then step by step, starting from simple_peripheral, tell us exactly what files you modify and where.

    I know it sounds tedious, but I'm sure we can figure out what's going on

    I will do the uninstall part at my side. but you haven't spoken about 1st problem. what is solution for such kind of issues?

    Thank you.

    Hi,

    Instead of doing what you did, can you create a periodic timer and then post a LED blink event when the timer times out?
    To check if it stack overflow issue, you can follow our software developer's guide section 9.5
