Keeps saying it’s disconnected but it’s clearly connected because it’s playing music... help me please. ### 1/5 — um what *2020-08-09* it doesnt even work???? i bought this bulb a little over a year ago and there was another app to do all the features but yall deleted it off the app store so i downloaded this one and it says its connected but it wont do anything im actually so confused and upset. ### 2/5 — No color change?! *2020-01-09* The bulb is fine, and it syncs right up to music. But can’t dim, strobe, or change color. Can’t even access controls to turn off remotely. Always have to use the hard switch. Isn’t this the point of a Blutetooth bulb?! ### 1/5 — Good luck *2019-11-12* No instructions for pairing, it said connected but nothing seemed to happen - my lightbulb works fine as a speaker without the app. The app seemingly does absolutely nothing. ### 5/5 — Works Fine *2018-12-15* Had zero problems connecting the bulb to Bluetooth and controlling it using this app. Maybe check that your light switch is in the on position and that you have Bluetooth turned on. Other than that I don’t see how you would have a issue. I do wish there was a option to have the colors change continuously but that’s my bad for not reading the box. ### 1/5 — Waste of money *2018-11-26* This product is worthless I’m really upset. that I’m having a hard time connecting via Bluetooth I feel like I wasted my money ### 4/5 — Help *2018-09-08* I can’t figure out how to make mine change colors I have the app but the bulb keeps diconnecting ### 1/5 — Colors don't change *2018-06-18* Speaker works; okay nothing to write home about. Colors and dimming doesn't work. ## Frequently asked questions about BSW ### What devices does BSW-A19 support? BSW-A19 is available for iPhone and iPad.
