Bluetooth® Module

Bluetooth 4.2 Low Energy plug-and-play module

The BlueMod+S42 is a high-performance Bluetooth 4.2 qualified single mode module. It features very low energy consumption and flexibility for designers such as Terminal I/O profile for serial cable replacement use cases as well as most GATT based Bluetooth profiles through a generic GATT implementation. Part of the BlueMod+Sx family, the BlueMod+S42 is swappable with previous generations without requiring new hardware or software spins. Although a single mode low energy module it offers a high throughput of up to 470kbit/s using Telit’s unique SPP like Terminal I/O service.

Development Kit

Telit’s BlueDev+S42 developer kits enables rapid prototyping of customer’s own firmware: solutions are based on a simple and powerful scripting language, Lua, supported by Telit Appzone development environment or using silicon vendor SDK for C++ development.

Evaluation Kit

The evaluation kits BlueEva+S42 are available to support Telit customers to evaluate and implement Bluetooth modules in their application. For each of the different FW Versions a separate Evaluation Kit is available.
