急急急！！！stm32f103利用nrf24l01发送数据，用PC串口检测是否发送成功，却一直只显示空白，跪求大神帮助~~~~

        &nbsp;代码是在stm32f103上利用nrf24l01模块发送数据（压力传感器的重物质量），但是串口什么都没有输出<img src="file://C:\Users\ADMINI~1\AppData\Local\Temp\E9BIPM$_`9}`VS07`VD9H1F.gif" />，跪求大神帮忙看下哪里有问题啊<img src="file://C:\Users\ADMINI~1\AppData\Local\Temp\T9QRV}V55@6B1SFLKDSC3LI.gif" /><br />

无泪了。。竟然加上&nbsp;&nbsp;NRF24L01_Check()函数就成功了，然而并不造为什么。。

看这个程序，串口是否有输出和无线是否发送成功没关呀。应该不会收无线发射影响呢。
