6. Troubleshooting
Q1: I heard a beep while connecting the scanner. Why did it not pair up with the iPad successfully?
A1: Press and hold the function key for 5 seconds, and until you hear a long beep, then you can use it normally.
Q2: How to enter Memory Mode?
A2: Hold the FN key for 5 seconds until 3 beeps.
Q3: When scanning the product barcode, I didn't hear a "beep" sound but a higher-pitched and a lower-pitched "ding", and the product was not added to the shopping cart.
A3: It means the scanner has been powered off (sleeping mode). Please press and hold the scan key for 5 seconds until you hear 3 beeps, then retry.
Q4: I have already connected the BT-680D to the POS app of iPad A, why does it still connect to iPad B automatically? Does the BT-680D have a device-binding function?
A4:
The BT-680D is a Bluetooth Low Energy that adopts the "broadcast pairing mode," which is different from the S700 Bluetooth scanner, which uses the traditional Bluetooth connection mode. Traditionally, before connecting to the iPad, you need to go to [Settings] > [Bluetooth] to pair the new device. After pairing, the iPad will remember the settings until the user unbinds and will not connect to other devices during the process. The user also needs to go to [Settings] > [Bluetooth] > [My Devices] to unbind.
A Bluetooth Low Energy device emits a signal, and the iPad will scan and receive the signal for pairing. During the process, you do not need to bind or unbind manually in the [Settings] > [Bluetooth].
Therefore, even if iPad A has been paired and connected to the BT-680D, as long as the iPad A is not nearby, the BT-680 will find the iPad closest to it (within around one meter) for connection, so BT-680D might be connected to iPad B.
To connect BT-680D to iPad A again, you can turn off the Bluetooth of iPad B first, and disconnect iPad B from BT-680D (you will hear three beeps). Turn on the Bluetooth of iPad A, open the POS app, and make sure it is within a one-meter distance from BT-680D. When you hear two beeps, it means that the reconnection to iPad A is successful.
