There are two possible reasons about this error info.
1. The software might be failed to recognize the serial port if you have unplug Bluno from your PC while the software in running and re-plug it to your PC again. If so, please restart the software again and try.
2. Bluno is NOT in Update Firmware Mode if you don't see the 2 LED (PAIR&LINK) flashing, i.e. you forget to press the button BOOT before you plug Bluno to PC.
