Hello I don't know exactly if it's possible to work, I'm planning to buy a cheap bluetooth speaker such as doss traveler and scavenge the parts, I would like to add more bluetooth range 1 - 2 feet for starter and would like to sync multiple different bluetooth speaker, I'm planning this ahead to present something like this on my thesis (3 yrs from now), I'm just not sure if it's possible or not would like to ask some guide, docs anything related if possible. Thanks
