CC2640R2F: Program halt when using GGS_SetParameter function

Hi F Chng,

For most part of your problem, take TI Christin advice. To get some understanding read the "CC2640 and CC2650 SimpleLink™Bluetooth® low energy Software Stack 2.2.1 Developer's Guide"

I have move my project (fbBri) from the same level as simpleperipheral at simplelink_cc2640r2_sdk_1_00_00_22\examples\rtos\CC2640R2_LAUNCHXL\blestack , to outside simplelink_cc2640r2_sdk_1_00_00_22.

I have advised you not to do this. This is what I did below. I added the sensortag folder to same level with simple_peripheral.

Christin, I work with F Chng.

Hi Christin,

I have change the maths and it works.  Thank you.

Now I am facing another problem.  Initially , originally, in the main has 2 task :

GAPRole_createTask();  //Origianlly is priority 3.

BridgeBLEPeripheral__CreateTask();  // Originally is 1,  I have change the priority of this task to 5, which is the highest among all.

Than I add a new task which is : 

Pwm__CreateTask();  // the priority is 1.

If I only run Pwm__CreateTask();,  (done by comment out the other 2 task ) , It is running and I observe it with breakpoint inside its for(;;) loop.

But, then, I add back the other 2 task (, BridgeBLEPeripheral__CreateTask();   and GAPRole_createTask();) ,  or just either 1 of these task.

After done this, my two other task  ( BridgeBLEPeripheral__CreateTask();   and GAPRole_createTask();)   does not operate. 

Program does not go into the Breakpoint inside for(;;) loop in ...Fxn function.

Is it that there are still some other code I need to change in order to add more tasks ?

I have change the constant ICALL_MAX_NUM_TASKS   inside icall.c , but still the same problem exist.

Is TIRTOS operates very similar to FreeRTOS ?

Please advice.

Thank you very much.

Cheers,

KF

Hi Christin,

Many thanks for your advice.

I will explore on using semaphore in TIRTOS and implement it.

But, may I ask, must I use semaphore ?  If I implement my 2 example task (simple_peripheral and my_pwm ) to priority 1, will it work ?

The reason is, for priority 1, both 2 example tasks will be allocate the same chance to execute by TIRTOS. 

Since it works with simple_peripheral alone, should it works also with other added task (same priority with simple_peripheral) ?

Please advice.

Thank you very much.

Cheers,

KF

If you don't use semaphore to pend the event(or event pend), then the first priority 1 task got executed will run forever, which means the other one will not be executed at all.

I recommend you to spend 1 day finishing up simplelink_academy training. Most of the question you asked which took you more than 1 day to solve are already explained in the training.

Finishing the training will benefit you a lot than just try and error.  Even though the training is for R1 device but the structure and the concept is the same.

Hi Christin,

Thank you very much.

I have study about Real Time Operating System in general but not specific to TIRTOS.
While I am doing debug now,  I will gain access to videos and Kernel document to explore more on TIRTOS.

Now, I have add a semaphore to the function call event_pend, to one of my task, which I modify from pwmled.c:
void Pwm__taskFxn(UArg a0, UArg a1)
{
.
.
.
    for(;;)
    {
        uint32_t events;
        //events = Event_pend(pwmLedSem, Event_Id_NONE, PWM_ALL_EVENTS, ICALL_TIMEOUT_FOREVER);
        events = Event_pend(pwmLedSem, Event_Id_NONE, PWM_ALL_EVENTS, ICALL_TIMEOUT_PREDEFINE);
        /* [kf] Defination : int_fast16_t PWM_setDuty(PWM_Handle handle, uint32_t duty) */
        PWM_setDuty(pwm1, dutyUs);
    }
}

From my understanding, Event_pend will check for my event handle " pwmLedSem" , which is a semaphore.

By this setting, it will check for any event (PWM_ALL_EVENTS) available every ICALL_TIMEOUT_PREDEFINE seconds and then it will post a semaphore and then the task will be waken.

By changing value of ICALL_TIMEOUT_PREDEFINE to longer time, execution will become slower, as observed when I put in a breakpoint at PWM_setDuty(...).

While waiting for a semaphore to be give out by event_pend,  another task should be able to schedule to run.  This task is static void SimpleBLEPeripheral__TaskFxn(UArg a0, UArg a1).

static void BridgeBLEPeripheral__TaskFxn(UArg a0, UArg a1)
{
  /* [kf] Refer to CC26...SimpleLink BLE ... Developer's Guide.pdf, Pg. 66,
     Figure 4-3. SBP Task Flow Chart. */

  // Initialize application
  BridgeBLEPeripheral__Init(); /* [kf] Original, Commented for debug only */

  // Application main loop
  for (;;)
  {

    uint32_t events;
    events = Event_pend(syncEvent, Event_Id_NONE, SBP_ALL_EVENTS, ICALL_TIMEOUT_PREDEFINE);
.
.
.
.
.
.
}

}

However, there program do not come into above function, as I observe with a breakpoint at BridgeBLEPeripheral__Init();  .  I have also change above function priority to 2.

The program will go into static void gapRole_taskFxn(UArg a0, UArg a1), as I have observe with breakpoint inside the function.

The program seems to go into only the last created task instead of all task.  It will continue execution of the last create task without giving out chance for other task.

Does this means the task control block of the last created task is place at the front of the of the heap memory and will be execute first ?

My current main() is describe as following:

  ICall_init();

  /* Start tasks of external images - Priority 5 */
  ICall_createRemoteTasks();

  /* Kick off profile - Priority 3 */
  GAPRole_createTask();     /* [kf] No other Task can have a high priority than GAPRole Task */

  SimpleBLEPeripheral__CreateTask();

  /* [kf] Add in pwm task for debug */
  Pwm__CreateTask();  /* [kf] Uncomment to troubleshoot no advertising */

}

The SimpleBLEPeripheral task is executed first when I place it at the last created task, as shown in the following.

This task will then take over the whole CPU and no letting other task to execute.

  ICall_init();

  /* Start tasks of external images - Priority 5 */
  ICall_createRemoteTasks();

  /* Kick off profile - Priority 3 */
  GAPRole_createTask();     /* [kf] No other Task can have a high priority than GAPRole Task */

  /* [kf] Add in pwm task for debug */
  Pwm__CreateTask();  /* [kf] Uncomment to troubleshoot no advertising */

SimpleBLEPeripheral__CreateTask();

}

Please help me o this issue.

Beside, may I ask a question ? 

semaphore can be use together with queue. 

May I know what is event_pend ?  is it semaphoare also ?  is it a combination of semaphore and queue ? 

Thank you very much.

Please advice.

Hi Christin,

Thank you very much.  Unfortunately I do not have CSPY. This application need CSPY, is it ?.

however, thank you very much and I will explore more into it.

  Thank you very much.

Hi Christin,

I am developing button function for my CC2640R2 project.  I am using CC2640R2 LAUNCHXL development board.

My code for Button.c is based on sensortag_keys.c code. 

However, may I know why when ever I  put in Semaphore_pend(ButtonSemaphore, BIOS_WAIT_FOREVER);  , my button interrupt will not work.

If without Semaphore_pend(ButtonSemaphore, BIOS_WAIT_FOREVER); in my static void Button__TaskFxn(UArg a0, UArg a1), my interrupt will work.

Which means, when button is pressed, program will goto my call back function  --->  void Button__Callback(PIN_Handle handle, PIN_Id pinId) . 

This is initialised in PIN_registerIntCb(ButtonInteruptPinHandle, Button__Callback).

The following is my code

int main()
{
.
.
.
.
.

  /* [kf] Add in Button task for debug */
  Button__CreateTask();

  /* enable interrupts and start SYS/BIOS */
  BIOS_start();

  return 0;
}



void Button__CreateTask(void)
{
  Task_Params taskParams;

  Task_Params_init(&taskParams);
  taskParams.stack = ButtonTaskStack;
  taskParams.stackSize = BUTTON_TASK_STACK_SIZE;
  taskParams.priority = BUTON_TASK_PRIORITY;

  Task_construct(&ButtonTask, Button__TaskFxn, &taskParams, NULL);
}


static void Button__TaskFxn(UArg a0, UArg a1)
{
  uint8_t debugButton2;
  /* {kf] Initialize Button */
  Button__Init();

  // Application main loop
    for (;;)
    {
        uint32_t events;

            Semaphore_pend(ButtonSemaphore, BIOS_WAIT_FOREVER);

            debugButton2 = debugButton2 +1;
    }
}


void Button__Init(void)
{
    Button__reset();

    ButtonInteruptPinHandle = PIN_open(&ButtonGpioState, ButtonPinTable);
    PIN_registerIntCb(ButtonInteruptPinHandle, Button__Callback);

    Util_constructClock(&periodicClock, Button__clockHandler,
                      100, 1000, false, 0);
}


void Button__Callback(PIN_Handle handle, PIN_Id pinId)
{
  switch (pinId)
  {

      case Board_BTN2:
        Button__processKeyRight();
        break;

      default:
        /* Do nothing */
        break;
  }
}


void Button__processKeyRight(void)
{
    uint8_t debugRbutton;

    if (PIN_getInputValue(Board_KEY_RIGHT))
    {
        keys &= ~SK_KEY_RIGHT;
    }
    else
    {
        keys |= SK_KEY_RIGHT;
    }

    Semaphore_post(ButtonSemaphore);

    debugRbutton = debugRbutton + debugRbutton;
}

When button is pressed, program is not going to void Button__processKeyRight(void) to process its data.

Please advice.

Thank you very much.

Hi Christin,

I am also facing same "sendWaitMatchCS(ICall_getEntityId(), msg, matchGapSetParamCS);"

I am using,

CCS Version - 7.1.0.00016

BLE Stack 2.2.1

Example code from 

To test the maximum Throughtput between two boards. Here - i loaded the peripheral stack and application code.

Here i attached the images to help to understand more about my code.

the above images are shows the flow of the program.

and the struck is happening inside the 5th function 

Inside this function = static bStatus_t sendWaitMatchCS(ICall_EntityID src, void *msg, ICall_MsgMatchFn matchCSFn)

"waitMatchCS(matchCSFn, (void **)&pCmdStatus);" is not giving any return response.

inside "WaitMatchCS" function its struck in return "ICALL_ERRNO_UNKNOWN_THREAD;" 

Could Please help me now?
