CoreSwap

Switches the ambient sound mode of Anker Soundcore headphones and earbuds from the app or, more usefully, from separately launchable activities that MacroDroid (or any launcher/automation tool) can start directly.

On launch a mode activity looks at Bluetooth, finds which of your configured Soundcore devices is actually connected, connects to it over RFCOMM, sets the mode, and disconnects. It shows no UI beyond a toast.

First run Open CoreSwap and grant the Bluetooth permission (Android 12+ only). Tap Add device, pick the Bluetooth-bonded earbuds, then pick the matching model (for example SoundcoreA3040 for the Q45). The model cannot be detected automatically — the engine requires it, so you have to say which device this is. Repeat for any other Soundcore device. The order devices are added is the tie-break order used when more than one is connected and none is actively playing audio. Devices actively receiving audio win over that order, so with two devices connected the one you are listening to is the one that gets switched.
