Here is a photo of my setup. (The CoDrone is on nearby)

This does not help, but thanks anyway.

The first time I tried pairing I got this output:

Port : [COM1]

Out[1]: False

The second time I attempted pairing, after disconnecting everything, I got the same error that I initially posted. I am sure that the issue is not being caused by any of the potential causes you described. Can you offer any more help?

I have successfully installed the CoDrone library. However, I keep getting the same error message:

SerialException Traceback (most recent call last)

I have resolved this issue.

I have installed Python software through the Anaconda distribution. Using pip to install the library may break my installation of Anaconda. Is there any alternative to pip?
