In order to use two devices together with Bluetooth, you need to make them known to each other. This process is called "pairing".

What is "Pairing"?

The Bluetooth protocol does not involve a login or similar authentication. To avoid abuse, only "trusted devices" are accepted. The process of making a device known as "trusted" is called pairing: On the first connect, the user is asked whether the connecting device might be trusted. Usually, the confirmation process requires a PIN to be entered on both devices, which then is used as a kind of "passphrase" for subsequent connections.

When should I use this tag?

If you have trouble to convince two devices (at least one of them being an Android device, of course) to pair with each other -- either initially, or on subsequent connects (e.g. a device "forgetting" its pairing data, or the like)

Related tags

In some cases, another tag might be more (or additionally) fitting:

  • : If your question is about sharing the internet connection via Bluetooth, this is the better fitting tag
  • : Issues concerning the HeadSet Profile. Might be used in addition or instead, depending on your issue.
  • : To be used for audio devices communicating via Bluetooth. Might be used in addition or instead, depending on your issue.
  • : For generic Bluetooth questions not fitting one of the more specific categories. Do not use this together with , but rather instead.
