CAN连接断开后调用CAN收发的线程会直接卡住，这样正常吗？

我刚找到解决办法了，关了CAN的自动重发功能就不会卡住了。原来我这里设置的是ENABLE，现在改成了DISABLE。

static rt_err_t _can_config(struct rt_can_device *can, struct can_configure *cfg)
{
    struct stm32_can *drv_can;
    rt_uint32_t baud_index;
    RT_ASSERT(can);
    RT_ASSERT(cfg);
    drv_can = (struct stm32_can *)can->parent.user_data;
    RT_ASSERT(drv_can);
    drv_can->CanHandle.Init.TimeTriggeredMode = DISABLE;
    drv_can->CanHandle.Init.AutoBusOff = ENABLE;
    drv_can->CanHandle.Init.AutoWakeUp = DISABLE;
    drv_can->CanHandle.Init.AutoRetransmission = DISABLE; //ENABLE
    drv_can->CanHandle.Init.ReceiveFifoLocked = DISABLE;
    drv_can->CanHandle.Init.TransmitFifoPriority = ENABLE;
    ...
}
