Bluetooth 5.4 LE Host

Overview

Packetcraft Host efficiently enables Bluetooth 5.4 PAwR (for Electronic Shelf Labels, Automotive, Agriculture and other smart senors) and LE Audio / Auracast atop embedded systems operating with limited CPU & memory resources and under battery constraints.

Consisting of the Bluetooth LE host protocol stack, GATT profiles, and LE Audio profiles, the Packetcraft Host production-ready Bluetooth 5.4 qualified solution supports mandatory and optional features.

When combined with Packetcraft Controller and/or Packetcraft LC3, licensees receive a comprehensive, fully-integrated BLE solution from a single software supplier with exceptional support.

Also offered is Packetcraft Host Tester, a companion test tool allowing Packetcraft’s host protocol stack and profiles to be tested on a PC and can interface to PTS, the official qualification tool by Bluetooth SIG.

Packetcraft’s feature-rich and mature software dates back to 2009 and is extensively tested and widely adopted. Testing in conjunction with test partners supports interoperability, quality, and reliability.

Packetcraft’s innovation and first-to-market Bluetooth qualifications support customers with early access to new features and mature extensively tested solutions.

Bluetooth 5.4 Featuring PAwR, a New Ultra-low Power Networking Technology (incl. ESL enablement)

As shown in this Packetcraft PAwR trace captured on the Ellisys Explorer protocol analyzer, an AUX_SYNC_SUBEVENT_RSP message is transmitted in the response slot from an ESL device (price tag) to a gateway which can include telemetry data such as temperature, battery level, and stock level. From this trace one can see there is enough bandwidth to receive telemetry data from many devices. A single ESL gateway has a theoretical capacity of supporting two-way communication with tens of thousands of ESL price tags.
