Out of the two LEDs at the front side, the left one indicates the communication and Bluetooth connection state.

If the left (communication and Bluetooth) LED blinks even when not printing, it means that a mobile device is connected to the Nemonic printer via Bluetooth, and it is ready to print.
If the mobile device finishes printing memos to the printer, the LED stops blinking.
Under the state that the left LED blinks because a mobile device is connected to the Nemonic printer, other mobile devices cannot connect.
When the LED stops blinking after the connected mobile device finishes printing, any other mobile devices may connect to the Nemonic printer.
For iOS, if Bluetooth connection is established from the device settings, the printer may remain as continuously connected. Select the Nemonic printer connected from Settings > Bluetooth, disconnect it, and connect it from the Nemonic app.
