I always thought, that wifi opposed to bluetooth is mostly used to connect to a hotspot and that most desktop wifi chips lack the possibility to use them as a wifi hotspot (while its no problem with the chips used in smartphones). Apparently this is not the case since newer chips have support for wifi-direct.

(I used bluetooth to build an ad-hoc-network (I would call it a mesh like network) but only found out about wifi-direct now.)

Question:

I was wondering what advantage bluetooth 4.0 LE has over wifi direct other than the possibly lower energy consumption (accept that newer bluetooth 4.1+ can send and receive at the same time as far as I know).

There are of course multiple pages who show the differences, according to this one for example the only advantage of bluetooth 4.0 LE over wifi-direct it the possibly lower energy consumption.

So if I would have to argue why I used bluetooth 4.0 LE over wifi-direct I would have to say that I did so because bluetooth 4.0 LE might reduce energy consumption.

  • This review also seems to come to the same conclusion.
  • This review claims that bluetooth is still more important in the OEM market at least in the short term.

Additional Information:

Range and bandwidth are the advantages of wifi-direct, I'm searching for advantages of bluetooth 4.0 LE, In my case I transfare only small amounts of data (json files around 4 Kilobyte) over a short distance between 1-5 Meters, so this does not matter. Currently I try to find out whether its easier to set up bluetooth than wifi-direct e.g. if this might be an advantage of bluetooth 4.0 LE over wifi-direct.

  • Range would be an important difference... – Twisty Impersonator Jan 18 '18 at 14:17

    That additional info would be a good edit to your question. – Twisty Impersonator Jan 18 '18 at 16:39
