When I was using USB cable to interface with the codey, the labtop prompted me that it was connected. When I uploaded my program into the codey, the codey didn’t move or respond at all. I’m using labtop to interface with the codey. My Com port also didn’t show “CH340” as indicated in your reply earlier. Please find the photo as attached for your reference. Can you please help? With bluetooth dongle, can I interface my labtop with the codey.
