Nordic Semiconductor nRF52832 User Manual

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).
