FlooGoo FMB110 - 1000 meters line-of-sight range

FMB110 is a dual-mode class 1 Bluetooth V5.1 module. With its 20dBm transmission power and -96.5dBm sensitivity, it offers more than 1000m line-of-sight communication (SPP) range with another FMB110 module.

It integrates all necessary components including chip antenna, RF PA & filter, baseband and profile processors into a small form factor module in plated half-holes footprint. With its multiple internal processors, it runs a full Bluetooth stack including multiple profiles such as SPP, HID, OPP, HFP/HSP and GATT-based BLE profiles. It supports high-quality A2DP codecs such as aptX. Wideband SBC is supported for HFP/AG applications. It also supports cVc for noise depression and echo cancellation for headset/speaker applications.

FMB110 also supports a Flairmesh proprietary GATT-based BLE profile that works like SPP. It can be used to build a bi-directional raw data channel over BLE to iOS and Android devices. Retransmission is handled automatically when using the iOS/Android lib we supply. So the user can focus on their data. With its 2M BLE PHY, it can achieve >10kBytes/s reliable(lossless) throughput from handsets to the module. We provide iOS and Android libs to help customers to integrate this capability into their apps with simple lib APIs instead of directly handling the complex OS-related BLE APIs. If latency is the most concerning factor, the lib also provides APIs to achieve even higher raw data throughputs on both mobile platforms. The profiles on the module can be controlled by an ASCII command-based control interface, either on its UART or USB port (virtual COM on Windows/MAC/Linux without an additional driver). Together with the aforementioned libs, it helps customers to integrate Bluetooth functionality into their applications with minimum effort.

The module has been fully tested and qualified for the US, European and Australian/New Zealand markets.

Please check the datasheet for full technical details. We also supply Kicad V5 design lib of the schematic symbol, PCB footprint and 3D model (STEP format).
