What's new in Bluetooth 5.4?

Bluetooth® version 5.4 is the latest specification introduced by the Bluetooth SIG. Bluetooth 5.4 offers two new enabling features, including Periodic Advertising with Response (PAwR) and Encrypted Advertising Data (EAD), that could unlock the potential of electronic shelf label (ESL) solutions for broader acceptance and rollout in the retail world.

Bluetooth 5.4's PAwR is a new Bluetooth Low Energy (LE) logical transport that provides efficient, bi-directional communication in a large-scale one-to-many (star) topology that supports up to 32,640 devices. Since ESL and Shelf Sensor devices are generally powered using batteries, retailers will greatly benefit from this PAwR feature.

Furthermore, for the connectionless scenario, under Bluetooth 5.4 EAD features, the advertising data can be encrypted in totality or in a more specific subset. This capability secures the data in the advertising packets that are shared over PAwR thus greatly minimizing unauthorized access and/or tampering.

Bluetooth 5.4 further expands the range of Bluetooth applications and standardizes specifications for more markets. EDOM provides developers with a one-stop professional consulting service and technical support. Contact us to learn how our Bluetooth portfolios could maximize the new Bluetooth 5.4 features.
