CC2642R 怎样使能串口显示，即系统的uart_display

simple_perial 这个例程怎么开启这个打印功能，只勾选uart_log 没效果

case GAP_LINK_ESTABLISHED_EVENT:
{
gapEstLinkReqEvent_t *pPkt = (gapEstLinkReqEvent_t *)pMsg;

BLE_LOG_INT_TIME(0, BLE_LOG_MODULE_APP, "APP : ---- got GAP_LINK_ESTABLISHED_EVENT", 0);
// Display the amount of current connections
uint8_t numActive = linkDB_NumActive();
Display_printf(dispHandle, SP_ROW_STATUS_2, 0, "Num Conns: %d",
(uint16_t)numActive);

if (pPkt->hdr.status == SUCCESS)
{
// Add connection to list and start RSSI
SimplePeripheral_addConn(pPkt->connectionHandle);

// Display the address of this connection
Display_printf(dispHandle, SP_ROW_STATUS_1, 0, "Connected to %s",
Util_convertBdAddr2Str(pPkt->devAddr));

// Enable connection selection option
tbm_setItemStatus(&spMenuMain, SP_ITEM_SELECT_CONN,SP_ITEM_AUTOCONNECT);

// Start Periodic Clock.
Util_startClock(&clkPeriodic);
bleLinkState = 1;
}





Display_printf 這個怎么沒輸出

我看sdk的蓝牙部分好多都调用了Display_printf 这个函数，但是没见着串口有什么输出。

使用了的串口有输出的啊，simple_peripheral中就有输出
