Packetcraft Controller sets a high bar for features, robustness, and efficiency.

Packetcraft’s innovation and first-to-market Bluetooth qualifications support customers with early access to new features and mature extensively tested solutions. Packetcraft is the first independent software company to have a Bluetooth 5.4 qualified solution that includes the host protocol stack and link layer with support for all low energy features of the specification including Periodic Advertising with Responses (PAwR).

Additionally, Packetcraft’s link layer achieved first qualification with Bluetooth 5.3 isochronous channels, which enable multi-stream audio and Auracast™ broadcast audio.

Packetcraft Controller implements a Bluetooth link layer with optional 802.15.4 MAC, using a common radio event scheduler for simultaneous combo operation.

Packetcraft Controller also offers an optional Link Robustness Package helps maintain link quality and coexistence with neighboring networks. This Package was developed to improve the quality and streaming performance of LE Audio applications and includes interference Detection and Avoidance (DAA), dynamic closed loop power control of the transmit PA and receiver LNA, and supports receive-side antenna diversity. Products can use DAA to help comply with European radio regulations while transmitting at higher power. The package is available for certain chipsets, please inquire about platforms supported.

Packetcraft Controller is ideal for Bluetooth chip companies looking to develop unique products with full access to source code. Packetcraft’s licensees expect to bring commercial products in 2024.
