I joined this forum to exchange some knowledge about the technology and seek a type of speaker that stays connected to BT always. SO far I have bought and returned 5 small units because they all do the same darn thing; they shut off if no audio is transmitted. I am looking for a speaker that I can use and move around with me to work in conjunction with an Echo Dot. I am very hard of hearing so this becomes my remote voice for Dot as well as my alarm clock. I am looking for a dot-sized speaker that will stay on (in idle mode) and play the alarm to wake me. As most speakers turn off, they do not work in this way. Does anyone know of a speaker that keeps the BT link active for hours or until the battery reaches a shut-down point?
