Laird Connectivity has extended its development partnership with Silicon Labs to add to its Bluetooth LE portfolio.

The upcoming Lyra 24 series of flexible Bluetooth Low Energy (LE) modules, USB adapters and development kits delivers feature and performance enhancements for scalable Bluetooth LE development.

The series marries the benefits of Silicon Labs hardware, software and tools with Laird’s application software, services, certification and support. This partnership continues to provide multiple software development options suited to users’ resources and skillsets in Bluetooth LE-enabled product development.

Based on the Silicon Labs EFR32BG24 SoC, the series delivers on the silicon’s features including a Cortex-M33 with 1536kbyte flash and 256k RAM, Bluetooth 5.3 connectivity, secure vault high, AI and ML hardware accelerator, high sensing ADCs, and an extended industrial temperature rating.

“We are pleased to continue our partnership with Silicon Labs by expanding on the successful Lyra series, bringing major performance and feature enhancements to our portfolio with the new Lyra 24,” said Jonathan Kaye, vice president at Laird Connectivity. “Together through this partnership, customers can scale up their Bluetooth LE design for tomorrow’s connected world.”

From a software perspective, the series lets users choose from two firmware options for their application development, supporting either hosted or hostless operation. This includes Laird’s AT command set, developed from years of Bluetooth LE experience and easily portable from original Lyra implementations. The extensible AT option provides robust easy-to-use firmware for any user regardless of their Bluetooth LE expertise or host MCU. Alternatively full SDK and stack access for C code development with integrated support for Lyra 24 devices is included in Silicon Labs’ Simplicity Studio IDE.

“Partnerships with Laird Connectivity help to expand the usability and simplify the development process for our users,” said Anders Pettersson, director at Silicon Labs. “Our goal is to make it so developers can use the tools they’re comfortable and familiar with to build cutting-edge IoT applications on Silicon Labs SoCs, and our partnership with Laird Connectivity is a key step in providing that to our customers.”

The Lyra 24 series is for a broad range of battery-powered IoT device applications including professional lighting, asset tags and beacons, secure medical peripherals, and industrial IoT sensors. Modular FCC, ISED, EU, UKCA, MIC, KC and Bluetooth Sig approvals extend to OEM designs with no new testing, enabling faster time to market and reduced development risks.
