What is the speaker’s Bluetooth name?

If you connect your speaker to your device through Bluetooth, the display name in your device’s Bluetooth devices list will be either BLAST or MEGABLAST.

Once you’ve connected, you can change the name of your speaker from the app. With the speaker connected, open the app and in the top right, tap the gear icon. You can then change the name of your speaker by tapping on the Speaker Name field.
