如题所示，我正在使用GR5515的SDK开发一款门锁配件，但是当我需要同时使用两个串口时，一个用于调试打印，另外一个与外设通信时却 出现了问题。
串口0 用与 外设设备串口通信，波特率115200
串口1 用于本机的调试LOG信息打印 波特率115200 同样也是
问题现象是: a.为啥串口0 接不到外设的串口信息，或者是接到了信息 却是阻塞了本机 现象是死机了一般
b. 当接到外设传的串口信息后(uart0 的RX) 才打印LOG (这个是uart1的TX)
可能造成的原因是代码本身没理解还是，请你们分析分析一下，可以吗？
下面是详细代码：
这个 是调试串口的 初始化代码：
/*********************************************************

static void ty_uart2_rx_handler(app_uart_evt_t * p_event)
{
switch (p_event->type)
{
case APP_UART_EVT_RX_DATA:
// tuya_ble_gatt_receive_data(g_rx_buffer, p_event->data.size);
//tuya_ble_common_uart_receive_data(g_rx2_buffer, p_event->data.size);

这个是 与外设通信的 uart0 的初始化代码：

我想确定一个问题是：
在串口接收函数中，APP_UART_EVT_RX_DATA 这个枚举类型的值，应该怎么处理？？
