CC2640R2L: 加密连接

您好，

您这里指的是连接配对的加密还是传输内容的加密？

连接配对的加密

您好，

感谢您的对TI产品的关注！为更加有效地解决您的问题，我需要多一些时间查看这个问题，稍后会为您解答。

好的，麻烦您了！

您好，

没事，有结论会及时联系您。

感谢您的解答！我详细看一下这篇文档。

您好，

后续还有问题可以再发帖提问。

感谢您的支持。

您好,

我有两个关于配对的问题想要请教一下

1、我在初始设置时已经把配对后绑定选项设置成false了，但是使用手机成功连接后还是会自动绑定设备。设置的代码如下

    // Don't send a pairing request after connecting; the peer device must
    //uint32_t passkey = 0; // passkey "000000"
    // initiate pairing
    uint8_t pairMode = GAPBOND_PAIRING_MODE_INITIATE;
    // Use authenticated pairing: require passcode.
    uint8_t mitm = TRUE;
    // This device only has display capabilities. Therefore, it will display the
    // passcode during pairing. However, since the default passcode is being
    // used, there is no need to display anything.
    uint8_t ioCap = GAPBOND_IO_CAP_DISPLAY_ONLY;    
    // Request bonding (storing long-term keys for re-encryption upon subsequent
    // connections without repairing)
    uint8_t bonding = FALSE;

    uint8_t gapbondSecure = GAPBOND_SECURE_CONNECTION_NONE;//GAPBOND_SECURE_CONNECTION_ONLY ;

    GAPBondMgr_SetParameter(GAPBOND_SECURE_CONNECTION, sizeof(uint8_t), &gapbondSecure);
    //GAPBondMgr_SetParameter(GAPBOND_DEFAULT_PASSCODE, sizeof(uint32_t), &passkey);
    GAPBondMgr_SetParameter(GAPBOND_PAIRING_MODE, sizeof(uint8_t), &pairMode);
    GAPBondMgr_SetParameter(GAPBOND_MITM_PROTECTION, sizeof(uint8_t), &mitm);
    GAPBondMgr_SetParameter(GAPBOND_IO_CAPABILITIES, sizeof(uint8_t), &ioCap);
    GAPBondMgr_SetParameter(GAPBOND_BONDING_ENABLED, sizeof(uint8_t), &bonding);

2、我在启动配置后进入密钥连接事件，按照我的需求是如果连接密钥输入错误会断开连接。但是实际输入错误的密钥后，设备反而会快速连接。我在此处设置的代码是否有问题？

我在配对完成后的事件中添加了断开连接的处理事件。

/*********************************************************************
 * @fn      SimplePeripheral_processPairState
 *
 * @brief   Process the new paring state.
 *
 * @return  none
 */
static void SimplePeripheral_processPairState(spPairStateData_t *pPairData)
{
  uint8_t state = pPairData->state;
  uint8_t status = pPairData->status;

  switch (state)
  {
    case GAPBOND_PAIRING_STATE_STARTED:
      Display_printf(dispHandle, SP_ROW_CONNECTION, 0, "Pairing started");
      break;

    case GAPBOND_PAIRING_STATE_COMPLETE:
      if (status == SUCCESS)
      {
        Display_printf(dispHandle, SP_ROW_CONNECTION, 0, "Pairing success");
      }
      else
      {
        //Disconnected 
        HCI_EXT_DisconnectImmedCmd();

        Display_printf(dispHandle, SP_ROW_CONNECTION, 0, "Pairing fail: %d", status);
      }
      break;

    case GAPBOND_PAIRING_STATE_ENCRYPTED:
      if (status == SUCCESS)
      {
        Display_printf(dispHandle, SP_ROW_CONNECTION, 0, "Encryption success");
      }
      else
      {
        Display_printf(dispHandle, SP_ROW_CONNECTION, 0, "Encryption failed: %d", status);
        //HCI_EXT_DisconnectImmedCmd();
      }
      break;

    case GAPBOND_PAIRING_STATE_BOND_SAVED:
      if (status == SUCCESS)
      {
        Display_printf(dispHandle, SP_ROW_CONNECTION, 0, "Bond save success");
      }
      else
      {
        //Display_printf(dispHandle, SP_ROW_CONNECTION, 0, "Bond save failed: %d", status);
          //HCI_EXT_DisconnectImmedCmd();
      }
      break;

    default:
      break;
  }
}

您好，

这个麻烦您重新开个帖进行提问。
