I have a Bluno Nano Arduino BLE Bluetooth Microcontroller.
I can upload sketches via USB and the Arduino IDE but when I try using Windows Arduino Remote Experience, I can’t connect by USB or BLE 
I’ve found the page that explains updating the firmware but my board (v1.3) doesn’t have an AT switch.
Any ideas?
Hi,
Do you mean the Bluno Nano Arduino BLE Bluetooth Microcontroller (RB-Dfr-572)?
If so, you can find more information concerning on the product page under Useful Links.
Also, as you may see in the long description, the device has a button specifically used for firmware updates.
You can find more details on the firmware update from the manufacturer’s Wiki. Please note that the Bluno Nano is updated the same way as the other Bluno boards are, since they all use the same TI CC2540 chip.
Sincerely,
