      @smilebean So 4000ms and 3000ms delay is not normal, what code are you running? Do you have the BLE module driver installed on your computer? the SiLabs Driver? Also can you post the code you are trying to run here? Thank you!

        The FPV transfer to PC have delay 3000~4000ms. Is it normal?

                @smilebean I can explain everything over the video call. I will be on the website https://appear.in/robolink-support let me know if the site works for you. It is best if you use a google chrome browser.

                          @smilebean Please let me know when you are available for a video call I will be able to guide you through a lot of the content.

                            Hello @smilebean I highly recommend setting up exactly as we did, use PyCharm as we will be able to help you out with your issues. Please follow the guide for PyCharm. Also that error appears when the CoDrone BLE module is not connected.

                              About fpv_videosave ,when I press "Q", my program(video frame) will crash. And I can't open the video I save.
                              About keyControl,I can't connect my drone . 0_1529633491930_problem.png

                              And can you give some example about CES video, or give me some hint to do that?
                              Thank you for help.

                                  @robolink_arnold I think @smilebean is referring to the CES video he linked in the original post. We'd be able to walk you through how we did those OpenCV demos in a video call, if you're interested. It's a project we're planning to work on eventually, but it's currently on hold, so documentation is still minimal.

                                  Would you like to do a call?

                                        Hello @smilebean here are some of the sample programs we made. If you want and can we should set up a video call to guide you on using CoDrone with OpenCV.
