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.

Does allowing Bluetooth discovery consume more power?

Privacy issues and of course turning Bluetooth completely off-- all aside, if I enable "Make device discoverable" will that draw more power than not? As long as Bluetooth is "on", is it always drawing the same power regardless?
