Undok or Bluetooth?

[Kodak2]

Has anybody had any experience using the Undok app for streaming music to WiFi speakers, and are there any advantages over using Bluetooth speakers? I only need to stream to 1 speaker in 1 room, not a multi room setup.

Bluetooth is limited in range, Wifi has about 10 times the range. (Also, not that it matters in this case, Wifi is a one-to-many setup, Bluetooth is one-to-one.)
