NINA-B1 series
Stand-alone Bluetooth low energy modules
System integration manual
Abstract
This document describes the system integration of NINA-B1 series stand-alone Bluetooth® low
energy modules. With embedded Bluetooth low energy stack and u-connectXpress software, these
modules are tailored for OEMs who wish to have the shortest time-to-market. The OEMs can also
embed their own application on top of the integrated Bluetooth low energy stack using Nordic SDK
or Arm® Mbed™ integrated development environment (IDE).
