协议栈SimpleBLEPeripheral例程修改添加HalLedSet问题，求解。

我参考了协议栈SimpleBLEPeripheral和SimpleBLEPeripheralStack的例程，想添加自己的代码，在 SimpleBLEPeripheral的simpleBLEPeripheral.c文件中的static void SimpleBLEPeripheral_init(void)函数中，添加以下代码，提示编译出错，无法生成.out文件。添加的代码如下：

static void SimpleBLEPeripheral_init(void)
{
  // ******************************************************************
  // N0 STACK API CALLS CAN OCCUR BEFORE THIS CALL TO ICall_registerApp
  // ******************************************************************
  // Register the current thread as an ICall dispatcher application
  // so that the application can send and receive messages.
  ICall_registerApp(&selfEntity, &sem);

  // Hard code the BD Address till CC2650 board gets its own IEEE address
  //uint8 bdAddress[B_ADDR_LEN] = { 0xAD, 0xD0, 0x0A, 0xAD, 0xD0, 0x0A };
  //HCI_EXT_SetBDADDRCmd(bdAddress);

  // Set device's Sleep Clock Accuracy
  //HCI_EXT_SetSCACmd(40);

  // Create an RTOS queue for message from profile to be sent to app.
  appMsgQueue = Util_constructQueue(&appMsg);

  // Create one-shot clocks for internal periodic events.
  Util_constructClock(&periodicClock, SimpleBLEPeripheral_clockHandler,
                      SBP_PERIODIC_EVT_PERIOD, 0, false, SBP_PERIODIC_EVT);

添加的代码如上述红色部分，hal_led.h头文件已包含，而且HAL_LED=TRUE已定义。如下图：

出现的错误信息如下：

<Linking>

 undefined first referenced
  symbol       in file     
 --------- ----------------
 HalLedSet <whole-program>

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "SimpleBLEPeripheral.out" not built

>> Compilation failure
gmake: *** [SimpleBLEPeripheral.out] Error 1
gmake: Target `all' not remade because of errors.

我查看了HalLedSet()函数的原型，发现在hal_led.h头文件中，有如下定义

extern uint8 HalLedSet( uint8 led, uint8 mode );

这是一个外部函数声明，并没有发现函数体，请问在调用时是否需要重写这个函数，该如何重写？出现这个错误的原因是不是HalLedSet的问题，希望高手帮忙，小弟不胜感激。

xiaobailong24,

这个貌似是原先254x的接口，并非针对26xx，在新的SDK里面并没有包含其实体。

26的SDK里面我们基本上用IO口操作来控制LED。

嗯，我就是按照CC2540的教程修改的。SimpleBLEPeripheral例程，我想问一下要想添加自己的代码，或者自己的任务，具体的步骤是什么？谢谢

朋友，你编译通不过的问题弄好了么？求最后是怎么弄的。我搞了好多天了，感觉配置上全都正常。

看了你的帖子感觉就是我未来几周将会干的事。所以在你自己的帖子回复你了。

qq820250676，如果方便的话请加我QQ行吗？有些入门问题请教。。。和你发的帖子都沾边的那种问题。谢谢。
