Questions tagged [bluetooth]

The "generic" tag for issues related to Bluetooth, a wireless technology for exchanging data over short distances. Whenever possible, please use the more specific tag instead if such exists, e.g. 'bluetooth-audio', or 'bluetooth-tethering'.

What is Bluetooth?

While most people know it has to do with "wireless data transmission", only few are aware whom it actually was named after: Harald Bluetooth, also known as king Harald I of Denmark, who united dissonant Danish tribes into a single kingdom. Bluetooth was supposed to do the same with communications protocols, uniting them into one universal standard.

Actually, Bluetooth is rather short-range compared with other wireless network standards, and has a limited bandwidth. You can think of it as being peer-to-peer, with the peers making each other known first (see: ) before they do any other interaction.

When should I use this tag?

If your issue is related to Bluetooth, and there is no other, more specialized tag (see below) fitting.
