Bluetooth Modules

Robust Performance Bluetooth LE and Classic Modules

We have been designing and manufacturing Bluetooth modules for over 20 years and have solutions spanning Classic Bluetooth, all the way to the latest Bluetooth 5.4 specifications.

Secure, low power, cost efficient modules based on innovative silicon from Nordic Semiconductor, Silicon Labs, Infineon and Qualcomm (CSR).

Every module in our portfolio is backed by our core support offerings:

  • Free technical support inc 3D antenna scans & SCH reviews
  • Global access to FAEs
  • Test & Certification services
  • Multiple pre-certified antennas

  • 5.3

  • 5.2

  • 5.1

  • 5.0

Bluetooth 5.x Version Feature Advantages Improvement End User Examples
v5.4 Periodic Advertising with Response (PAwR) Exchange of application data using connectionless communication Energy efficient (Battery Life),
bi-directional, communication in a large-scale one-to-many topology
Electronic Shelf Label (ESL) and applications needing to send and receive messages between a central hub
device and a large number of other devices in a network
Encrypted Advertising Secure broadcasting of data in
advertising packets
Connectionless communication or encrypted advertising and scan response packets Broadcast topologies allowing portions of advertisement packet be exposed to any observer while other portions needing confidentiality can be read by an intended observer.
LE GATT Security Levels Characteristic Devices may now indicate the security mode and level required for all their GATT functionality Adds Attribute Permissions Door Lock for multitenant dwelling where only authorized users can access entry based on user list.
Advertising Coding Selection LE Extended Advertising now allows CODED Phy Selection Longer range or higher throughput Extended Advertisement Beacons & location/tracking services can be improved for greater data & information at longer distances or greater throughput
