我遇到的问题是，只有有时我会看GTKterm中的输出。我无法找到一个什么时候工作的模式，何时没有。我如何调试这个？
解决方案
我将如何调试这个？ p>
有关初学者的一些建议：
确保您的终端软件正在断言DTR信号。这是找到的解决方案这里。
暂时删除 power_manage（）的调用，以确保不是问题的一部分。 / p>
更改 APP_UART_FLOW_CONTROL_ENABLED 为 APP_UART_FLOW_CONTROL_DISABLED 以确定它是否为流控问题。在任何情况下，您不需要输出到PC的流量控制。如果您正在输入设备（特别是缓冲区长度为1），或者您正在向缓慢的缓冲设备发送数据，可能需要此功能。

I have an Arduino device that runs on the Nordic SDK (it's a Red Bear Lab BLE nano). I want to be able to do a serial print into GTKTerm to be able to debug what is going on in my code. To do this I have the following code:

The problem I am having is that only sometimes I will see an output in GTKterm. I am unable to find a pattern for when it works and when it doesn't. How would I go about debugging this?
解决方案
How would I go about debugging this?
Some suggestions for starters:
Ensure that your terminal software is asserting the DTR signal. That was the solution found here.
Temporarily remove the call to power_manage() to ensure that is not part of the problem.
Change APP_UART_FLOW_CONTROL_ENABLED for APP_UART_FLOW_CONTROL_DISABLED to determine whether it is a flow control issue. You will not need flow control for output to a PC in any case. It may be needed if you are inputting to the device (especially with a buffer length of 1) or if you are sending to data to a slow device with limited buffering.
Verify ERR_CODE after calling APP_UART_FIFO_INIT to ensure no problems occurred at that stage. Possible error codes are defined here.
