a) Please make sure to turn on the Bluetooth function if you want to connect to another device through Bluetooth.
b) If your Bluetooth enabled device requires a passkey and you don’t know what it is, try 0000 or 1234, or check the documentation which came with your Bluetooth enabled device.
c) If the Bluetooth enabled device uses a battery, connect your device to a power source and then try again. If the battery power level is too low, your device may be unable to pair with another device.
d) Check that your device is compatible with the Bluetooth enabled device. If the issue only persists in one Bluetooth device, the root cause may be because that Bluetooth device is incompatible with your tablet.
e) If another Bluetooth enabled device is already paired, cancel the paired device and try to re-scan the connection.
f) Try to reset or update your device. (Refer to Q How can I perform a factory reset on my device & Q How can I upgrade my device).
