Problems with SampleApp

Hello Daniel,

Have you looked at the "Z-Stack Sample Application For CC2530DB.pdf" to understand how to setup the Sample Application Demo Build - Jumper Settings.This is located at  C:\Texas Instruments\ZStack-CC2530-2.5.0\Documents\CC2530 after installing the Z-Stack. This document should help to answer your questions and provide you better understanding of the code.

Hi, i may have badly explained my problem.

I changed the code so that it would`t depend on jumpers, but on a define made previously.

Without NV_INIT and NV_RESTORE it works perfectly.

I put a printf function before and after ZDO_InitDevice(0) (Inside HOLD_AUTO_START block). And it tells me that before this function the device is a router, but after, it becomes a coordinator. And this is only with NV_INIT and NV_RESTORE. I am erasing flash every time i download the code by the way.

When i use CorrdinatorEB and RouterEB without HOLD_AUTO_START, sometimes it works. But with the latter compiler flag it forces the device to be of a type that it shouldn`t be.

On the opportunity of this topic, knowing how to leave and rejoin a network could help me debug this. But i am having difficulty to find how to do that. What function do i use?

Thank you for your time.

Daniel.

Hi Daniel,

 Yes you can change role without using the jumper. you can trigger it in the software itself. please find below the sample code

#define MY_LOGICAL_ROLE_ITEM_ID         0x0408

 //write the value using serial port or toggle it using the key press

 if ( keys & HAL_KEY_SW_1 )//up
    {

              NvFlg = 1//coordinator

                 (void)osal_nv_write(MY_LOGICAL_ROLE_ITEM_ID, 0, 1, &NvFlg);

}

 if ( keys & HAL_KEY_SW_3 )
    {

           NvFlg = 2//Router

                 (void)osal_nv_write(MY_LOGICAL_ROLE_ITEM_ID, 0, 1, &NvFlg);

}

void GenericApp_Init( byte task_id )
{

 (void)osal_nv_item_init(MY_LOGICAL_ROLE_ITEM_ID, 1, &NvFlg);
   (void)osal_nv_read(MY_LOGICAL_ROLE_ITEM_ID, 0, 1, &NvFlg);
    if(NvFlg)
    {
      #if defined ( BUILD_ALL_DEVICES )
          // The  target is setup to have BUILD_ALL_DEVICES and HOLD_AUTO_START
          //  we will start up a coordinator with 1 and Router with 2. Otherwise,
   

      if(NvFlg == 1)
                            zgDeviceLogicalType = ZG_DEVICETYPE_COORDINATOR;
     else if(NvFlg == 2)
                            zgDeviceLogicalType = ZG_DEVICETYPE_ROUTER; //ZG_DEVICETYPE_ENDDEVICE
     #endif // BUILD_ALL_DEVICES
      #if defined ( HOLD_AUTO_START )
        // HOLD_AUTO_START is a compile option that will surpress ZDApp
        //  from starting the device and wait for the application to
        //  start the device.
        ZDOInitDevice(0);
      #endif  
    }

}

Hope it helps.

Thanks and Regards

Hi, i didn't understand your point. I was already doing this:

#define BOARD1 //BOARD2  //Before downloading the code to the device i change this define).

void SampleApp_Init( uint8 task_id )
{

*Here i do iniatilization of keys (interruptions). I don't use HAL_KEY.

#if defined ( BUILD_ALL_DEVICES )
 #ifdef BOARD1
    zgDeviceLogicalType = ZG_DEVICETYPE_COORDINATOR;
#endif
    //else
 #ifdef BOARD2
    zgDeviceLogicalType = ZG_DEVICETYPE_ROUTER;
#endif

#if defined ( HOLD_AUTO_START )

    if(zgDeviceLogicalType == ZG_DEVICETYPE_COORDINATOR)
    printf("Coord\n");
  if(zgDeviceLogicalType == ZG_DEVICETYPE_ROUTER)
    printf("Router\n");
 
  ZDOInitDevice(0);
 
  if(zgDeviceLogicalType == ZG_DEVICETYPE_COORDINATOR)
    printf("Coord\n");
  if(zgDeviceLogicalType == ZG_DEVICETYPE_ROUTER)
    printf("Router\n");
#endif

-----------------------------

As you can see, i use printf to know the device type. And without NV it works perfectly, but when i try to use NV this printf function tells me that ZDOInitDevice changes the device type to coordinator every time.

Hi daniel,

 The above code you have mentioned suppose to work even with NV item.

So for  #define BOARD1 ---> you are expecting the coord right ?

 I am using with NV it works perfectly as expected.May be i didnt understand your requirement.Can you please eloberate your requirement?

Can you print the status as mentioned below with NV.

printf ("zgDeviceLogicalType  %d ",zgDeviceLogicalType) ----> display it using the LCD or Serial Port  ( intial value of NV  before assigning)

#if defined ( BUILD_ALL_DEVICES )
#ifdef BOARD1
    zgDeviceLogicalType = ZG_DEVICETYPE_COORDINATOR;
#endif
    //else
#ifdef BOARD2
    zgDeviceLogicalType = ZG_DEVICETYPE_ROUTER;
#endif

Thanks and Regards

This is the strange thing.

With this printf, before ZDOInitDevice(0), it prints ZG_DEVICETYPE_ROUTER.. but right after the function, it prints ZG_DEVICETYPE_COORDINATOR.

There is something inside the function, inside NV_RESTORE define that is changing the device type.

When i use other projects (CoordinatorEB and RouterEB) it works fine.

New information. I forced "zgDeviceLogicalType = ZG_DEVICETYPE_ROUTER;" in different locations inside ZDOInitDevice(0).

Awkwardly, the problem wasn't inside NV_RESTORE define.

The root of the problem lies in this line:

zgInitItems( FALSE );

But then, i don't know what is really the problem, but at least i could make it work.

And again, i am erasing the flash when i download the code.

Thank you for your time, and if you know what was happening please let me know.

Daniel.
