[参考译文] CC2640R2F：SimpleLink SDK SimpleCentral 角色示例代码 FPGA_AUTO_CONNECT MARCO

https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/1532447/cc2640r2f-simplelink-sdk-simplecentral-role-example-code-fpga_auto_connect-marco

工具/软件：

我发现 SimpleLink SDK 中有一个名为 FPGA_AUTO_CONNECT 的新 Marco for CC2640R2F 版本 5.30.0.11 示例代码、用于控制对 SimpleCentral_startGapDiscovery () 的函数调用。 我注意到当我手动调用这个函数时、程序将停止在函数 GAPCentral Role_Start 发现中工作。 有人能告诉我这个 simplelink SDK 中 Marco FPGA_AUTO_CONNECT 的确切含义吗？ 是否需要启用 GAP 发现？

以下是相关 SDK 示例代码：

#ifdef FPGA_AUTO_CONNECT
/*********************************************************************
 * @fn      SimpleCentral_startGapDiscovery
 *
 * @brief   Start discovering devices
 *
 * @param   none
 *
 * @return  none
 */
static void SimpleCentral_startGapDiscovery(void)
{
  // Start discovery
  if ((state != BLE_STATE_CONNECTED) && (!scanningStarted))
  {
    scanningStarted = TRUE;
    scanRes = 0;

    Display_print0(dispHandle, 2, 0, "Discovering...");
    Display_clearLines(dispHandle, 3, 4);

    GAPCentralRole_StartDiscovery(DEFAULT_DISCOVERY_MODE,
                                  DEFAULT_DISCOVERY_ACTIVE_SCAN,
                                  DEFAULT_DISCOVERY_WHITE_LIST);
  }
}

/*********************************************************************
 * @fn      SimpleCentral_connectToFirstDevice
 *
 * @brief   Connect to first device in list of discovered devices
 *
 * @param   none
 *
 * @return  none
 */
static void SimpleCentral_connectToFirstDevice(void)
{
  uint8_t addrType;
  uint8_t *peerAddr;

  scanIdx = 0;

  if (state == BLE_STATE_IDLE)
  {
    // connect to current device in scan result
    peerAddr = devList[scanIdx].addr;
    addrType = devList[scanIdx].addrType;

    state = BLE_STATE_CONNECTING;

    GAPCentralRole_EstablishLink(DEFAULT_LINK_HIGH_DUTY_CYCLE,
                                 DEFAULT_LINK_WHITE_LIST,
                                 addrType, peerAddr);

    Display_print0(dispHandle, 2, 0, "Connecting");
    Display_print0(dispHandle, 3, 0, Util_convertBdAddr2Str(peerAddr));
    Display_clearLine(dispHandle, 4);
  }
}
#endif // FPGA_AUTO_CONNECT

case GAP_DEVICE_INIT_DONE_EVENT:
      {
        maxPduSize = pEvent->initDone.dataPktLen;

        Display_print0(dispHandle, 1, 0, Util_convertBdAddr2Str(pEvent->initDone.devAddr));
        Display_print0(dispHandle, 2, 0, "Initialized");

        // Prompt user to begin scanning.
        Display_print0(dispHandle, 5, 0, "Discover ->");

#ifdef FPGA_AUTO_CONNECT
        SimpleCentral_startGapDiscovery();
#endif // FPGA_AUTO_CONNECT
      }
      break;
