# Edifier Speakers BLE: reconstructing M60 and M90 speaker control

> Edifier Speakers BLE reconstructs the M60 and M90 speakers' BLE control protocols and uses them in a Home Assistant integration. Its references describe model-specific GATT services, frame checksums, commands, responses, and limits; the integration exposes volume, source, EQ, playback, and selected device settings.
