/**
 * Example for Getting Started with nRF24L01+ radios. 
 *
 * This is an example of how to use the RF24 class.  Write this sketch to two 
 * different nodes.  Put one of the nodes into 'transmit' mode by connecting 
 * with the serial monitor and sending a 'T'.  The ping node sends the current 
 * time to the pong node, which responds by sending the value back.  The ping 
 * node can then see how long the whole cycle took.

我的问题是,在我运行这段代码之后,在串行端口监视器(arduino IDE内部)上,我得到了奇怪的字符,它看起来像:

我试过两种不同的Arduinos,Nano和Uno(都是中文版本),结果是一样的,所以可能是我的代码有问题。
你能告诉我它怎么了吗?

这是你的错误:

Serial.begin(57600);
