  • Remove old Bluetooth connections.
    • Say that faithful Bluetooth Reader usually connects to your partner's smartphone instead of yours. If you're having trouble pairing your phone with the reader, it could be because the reader is trying to connect to the old device. Some older devices are very simple. They just try to connect with the last thing they paired with. If a Bluetooth device was previously paired with something else, turn off that other gadget. If you are no longer planning on using that other gadget, unpair it from your Bluetooth device to prevent future issues. 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.

  • Delete a device from a phone and rediscover it -

  • Download a driver -
    • If you’re having problems pairing something with your mobile device, you might be lacking the correct driver. The simplest way to figure this out is to do an online search for the name of the device you’re trying to pair along with the word “driver.”
  • Update the hardware’s firmware -
    • RFID Readers Companies have been known to not pair with because the Bluetooth drivers in these systems didn’t work with Bluetooth 4.0. If you’re not sure how to get the latest firmware for your hardware, check with the device manufacturer.
  • Clear the Bluetooth cache (Android only) -
    • Sometimes apps will interfere with Bluetooth operation and clearing the cache can solve the problem. Go to Settings → Backup and restart → Reset network settings.
