1. Determine which pairing process your device employs. The process for pairing devices can vary. Sometimes, for example, it involves tapping a code into your phone. If your device requires a code, please type in "0000."
If you’re not sure how to pair a device, refer to its user guide.
2. Make sure Bluetooth is turned on. You should see the little Bluetooth symbol at the top of your phone’s screen. If you don’t, go into the settings to enable it.
3. Power the devices off and back on. A soft reset sometimes can resolve an issue. With phones, an easy way to do this is by going into and out of airplane mode.
5. Delete a device from a phone and rediscover it. If your phone sees a device but isn’t receiving data from it, sometimes it helps to start from scratch. In iOS settings, you can remove a device by tapping on its name and then Forget this Device. In Android settings, tap on a device’s name, then Unpair. After removing a device, start at step 1 on this list.
6. Make sure the two devices are in close enough proximity to one another. While you wouldn’t think someone might try to pair an iPad with a keyboard if the two weren’t sitting right next to each other, it’s probably worth noting that you should make sure any devices you're trying to pair are within five feet of one other.
7. Update the hardware’s software. If you’re not sure how to get the latest firmware for your hardware, check with the device manufacturer.
