The Bluetooth Special Interest Group (SIG) has just adopted the Bluetooth 5.4 Core Specification with features such as PAwR and EAD designed for Electronic Shelf Label (ESL) systems.
The Bluetooth 5.3 Core Specification was adopted in August 2021 with various improvements, and Bluetooth 5.4 now follows with features that appear to be mainly interesting for large-scale Bluetooth networks with support for bi-directional communication with thousands of end nodes from a single access point, as would be the case for Electronic Shelf Label or Shelf Sensor systems.
Four new features have been added to Bluetooth 5.4:
Silicon Labs says that their BG22 and BG24 microcontrollers can be used for Bluetooth 5.4 devices, while the BG21 family would be integrated into access points, so the good news is that Bluetooth 5.4 support does not appear to require new hardware, just a new firmware.
You can access the Bluetooth 5.4 Core Specification on the Bluetooth website, but since it’s over 3000 pages long, you may prefer reading the technical overview for more details about the new features. Further information may also be found in the press release and a blog post.
