Japanese module maker Kaga FEI has announced two Bluetooth Low Energy modules with embedded software for wireless communication.

The ES4L15MA1 and EC4L15MA1 are versions of the ES4L15BA1 and EC4L15BA1 wireless modules with embedded software. They use Nordic Semiconductor’s nRF54L15.

Because the modules include the functions required for Bluetooth LE communication, device manufacturers can produce products without having to develop wireless communication software from scratch. The modules can thus help reduce software development workloads, shorten product development cycles and lower development costs for a wide range of IoT devices.

The need for wireless connectivity in IoT applications is growing across markets such as industrial equipment, smart home and healthcare. At the same time, many device manufacturers face shortages of Bluetooth software engineers and longer development cycles. Demand is therefore increasing for modules with pre-integrated wireless communication functions that can be easily controlled by external devices via serial commands.

The modules support simultaneous connections to eight Bluetooth LE devices, making them suitable for applications that manage multiple devices, such as sensor networks and equipment monitoring systems.

Kaga FEI’s proprietary software is controlled via serial commands. Users can configure connections, control communication and use various Bluetooth LE functions by sending commands. The modules also support sending and receiving user-defined text data, enabling two-way communication between devices, making them suitable for replacing wired serial links with wireless connections.

A built-in antenna eliminates the need for antenna design. The modules have obtained Bluetooth SIG qualification and certifications for Radio Law MIC (Japan), FCC (USA) and ISED (Canada), helping reduce certification time and costs.

The ES4L15MA1 will be sampling from January with mass production starting a month later. The EC4L15MA1 is in mass production already. For more information, visit www.kagafei.com/jp/eng/.
