CC2640的SCS串口一次中断后将无法再次进入中断

初始化函数如下：

scifOsalInit();
scifOsalRegisterCtrlReadyCallback(scCtrlReadyCallback);
scifOsalRegisterTaskAlertCallback(scTaskAlertCallback);
scifInit(&scifDriverSetup);

scifExecuteTasksOnceNbl(BV(SCIF_SCUART_TASK_ID));

scifUartSetBaudRate(57600);

scifUartSetRxFifoThr(SCIF_UART_RX_FIFO_MAX_COUNT);

scifUartRxEnable(1);

scifUartSetEventMask( BV_SCIF_UART_ALERT_RX_FIFO_ABOVE_THR );

回调函数如下：

static void scTaskAlertCallback(void)
{

scifClearAlertIntSource();

scifUartRxGetChars(uart_rx,19);

scifAckAlertEvents();

SimpleBLEPeripheral_enqueueMsg(APP_SCUART_READ_EVT, NULL);

}

Alvin Chen：

Hi 请参考下面的demo ，我怀疑你的enqueue有问题 如果你想和APP 层通信大致请参考：

回复 Alvin Chen:

}

这是我的配置你可以去试试。我亲测正常。
