now I have a wireless module AC4490-200M. I am Configuring it by using Laird Technologies Config, but the software somtimes prompts a dialog "Failed to Enter Command Mode. Check all connections and serial port settings" when I press the bottom "Read Radio".The strangest thing is that sometimes it works and prompts a dialog with "Read successful".I am sure I am following the user manual. What does the correct operation look like?enter image description here
