If you have trouble pairing your Bluetooth device to your SoundLink speaker via NFC (Near Field Communication), try the following:
Make sure your Bluetooth device supports NFC. Refer to the owner's guide of your device for more infomation
Note: Apple smartphones use NFC for Apple Pay but might not support pairing Bluetooth devices via NFC
Go into the Settings menu of your device and make sure both Bluetooth and NFC are turned on
Tap the NFC touchpoint on the Bluetooth device to the top center of your SoundLink speaker. The device may prompt you to accept pairing
Note: You may have to tap different areas of the Bluetooth device to your SoundLink speaker to locate the device's NFC touchpoint. The touchpoint location varies by device but is commonly located on the back of smartphones.
Reset the device you are trying to pair. This is typically done by rebooting/restarting it or removing the battery and/or power cord for one minute
Reset the speaker by turning it on and then holding the power button for 10 seconds until it turns off
A factory reset clears the speaker's language setting and its paired mobile device memory, returning the speaker to original factory settings. Once reset, turn the speaker on and try again to pair the device.
Try pairing another NFC-enabled device. If the another device works, there may be an issue with the first device
