At Embedded World 2025 in Nuremberg, LM Technologies introduces it’s new range of Bluetooth Auracast innovations including the LM509 adapter and the LM923 module. These new products are ideal for developing voice and data applications across a diverse range of industries and environments.
LE Audio is a new framework for sharing and receiving audio between Bluetooth enabled devices. With Auracast, Bluetooth devices can broadcast audio to an unlimited number of receivers including headsets, earbuds and hearing aids. This opens the possibility of providing audio to users in the most crowded of settings such as bars, airports and gyms.
LE audio also improves the experience of sharing audio between individual devices, for instance from a phone to a set of earbuds. For one-to-one connections LE Audio improves both the battery life and audio quality, resulting in an improved user experience over Bluetooth Classic audio. LE Audio can also be used to create wireless surround sound entertainment setups. Bluetooth LE Audio transmitters can transmit multiple channels of audio to devices in the network, allow for multiple speakers to play synchronised audio from different, individual channels.
LE Audio opens new possibilities for wireless telephony, media and assisted hearing devices, allowing for greater battery life, richer sound and a more seamless user experience.
LM509 Bluetooth® 5.4 Dual Mode USB Adapter
The LM509 adapter is an ultra small solution which can deployed in a wide range of applications including industrial machines, consumer products and IoT applications; giving users access to all of the latest and legacy Bluetooth audio functionality. The LM509 is a plug and play USB adapter, compatible with Linux as well as Windows platforms from Windows 10 to Windows 11. The adapter allows your host computer to wirelessly communicate with other nearby Bluetooth 2.x, 4.x and Bluetooth 5.x enabled devices (such as iOS and Android devices, printers, keyboards, speakers, and headphones), providing a low energy connection and high quality data stream.
