FlooGoo FMA120 — LE Audio / Auracast™ Transmitter/Receiver & Relay
The FMA120 upgrades phones, laptops, TVs, and other sources via USB audio—no driver required on Windows, macOS, or Linux. It adds aptX Adaptive (incl. Lossless) and Auracast™ broadcast, plus LE Audio unicast for music and voice with LC3-capable headphones, speakers, earbuds, and hearing aids. It can also work as a receiver —plug it into a phone or computer to join nearby Auracast/LE Audio streams and listen through the host device. As a relay , it can pair to a legacy A2DP source (e.g., a TV) and rebroadcast that audio as an Auracast stream for multiple listeners.
Official Auracast™ Qualification (Bluetooth SIG)
Deployed at home and in community venues (e.g., churches) for accessible Auracast broadcasts.

Auracast™ Receiver
The FMA120 can transform your mobile phone into an Auracast receiver: listen to nearby public broadcasts on your phone’s speakers or forward to Bluetooth devices (headsets, earbuds, speakers) — even legacy hearing aids without native Auracast support.
User Guide: Auracast Receiver (PDF)
Update your FMA120 to the latest Receiver-mode firmware. Important: If you’re switching from transmitter to receiver firmware, run “Clear All” first to remove all previous pairings and avoid connection issues.
- AS1.0.7 — iOS FlooCast app support; receive Auracast on iOS and forward to connected Bluetooth devices, including hearing aids.
- AS1.0.6 — Android FlooCast app support; receive on legacy phones, headphones, earbuds, speakers, and hearing aids.
- AS1.0.5 — After install/reset, set target broadcast name in FlooCast (“Broadcast Name”). Use an app that routes the FMA120 microphone input to speaker to play audio.
Auracast™ Microphone
Turn phones into Auracast Microphone
Important: Please configure your FMA120 in Broadcast mode before plugging it into the phone.
Plug FMA120 into your phone (use a USB-C↔USB-A adapter if needed), open FlooMic, and speak. The app captures your voice and FMA120 broadcasts it as an LE Audio Auracast stream that any compatible listener can join—no pairing, just join the broadcast.
- Perfect for ad-hoc classes, campus tours, small talks, gyms, and quick stand-ups.
- Low-friction “plug-and-talk” setup; on-screen mute/level (UI may vary).
- Works with any Auracast-capable earbuds, speakers, or assistive listening receivers.
A2DP → Auracast™ Relay
The FMA120 can function as an A2DP-to-Auracast relay. With the specific firmware below, a legacy Bluetooth device that only supports A2DP to a single headset can act as an Auracast transmitter.
Important: Please perform a “Clear All” reset before switching to relay mode so the dongle can pair as a headset with new devices.
- AS2.0.0 — Initial release for A2DP→Auracast relay.
