求助！一个串口收，一个串口发，显示乱码

两个板子MINI和F407，打算用无线模块进行收发数据，MINI发送数据，F407接收数据再发给电脑，F407串口2作为接收端，串口1作为发送端，结果显示乱码，请各位大神看看我写的收发数据的程序有哪里不对```#include "app_uart.h"

#include "board.h"
rt_uint8_t uart_rx_data;
void test_thread2_entry(void* parameter)//串口2接收数据
{    
    if (uart_open("uart2") != RT_EOK)
    {
        rt_kprintf("uart2 open error.<br>");
         while (1)
         {
            rt_thread_delay(10);
         }
    }
   
        uart_rx_data = uart_getchar();
        //uart_rx_data = uart_rx_data + 1;          
}
void test_thread1_entry(void* parameter)//串口1发送数据
{  
    if (uart_open("uart1") != RT_EOK)
    {
        rt_kprintf("uart1 open error.<br>");
         while (1)
         {
            rt_thread_delay(10);
         }
    }
	while (1)
    {   
        uart_rx_data = uart_rx_data + 1;
        uart_putchar(uart_rx_data);

}            
          
}

int main(void)
{
    
    rt_thread_t tid1;
      rt_thread_t tid2;  
    tid1 = rt_thread_create("uart1",
                    test_thread1_entry, 
                    RT_NULL,
                    1024, 
                    2, 
                    10);

if (tid1 != RT_NULL)
        rt_thread_startup(tid1);
		
		
    tid2 = rt_thread_create("uart2",
                    test_thread2_entry, 
                    RT_NULL,
                    1024, 
                    2, 
                    10);

if (tid2 != RT_NULL)
        rt_thread_startup(tid2);
        
    return 0;
}
