nRF52832

Introduction

The example runs on Nordic nRF52832 SoC. The block diagram of this example is as

follows:

In this example, nRF52832 acts as a forwarder, to forward command packets and

return packets between the NSP32 module and the Android phone. The Android app

can wirelessly (through bluetooth) control NSP32 module and get the spectrum data.

Note: This example must run in conjunction with the "Android SpectrumMeter" APK

installed on an Android phone. Please check "NSP32 Java API for Android / desktop"

for getting this Android project and APK.

API Source File Location

1) The API source files are located under

[/examples/nRF52/SpectrumMeter/NanoLambdaNSP32/], along with

nRF52Adaptor.h and nRF52Adaptor.cpp tailored for nRF52.

2) NSP32CWrapper.h and NSP32CWrapper.c are also provided under the same

folder, to enable NSP32 API being called from C source code (i.e. main.c).
