<WRAP centeralign>{{:nblocks:n-pro-30-01.jpg?300|}}</WRAP>

===== Overview=====
<poem>
[[nblocks:n-ble|n-PRO-30]] is a simple Bluetooth Low Energy board  based on Nordic nRF58232. It consists of temperature/humidity sensor, acceleration sensor and ambient light sensor which can be used to collect data and transmit it over bluetooth.  The board supports the standard Nordic Software Development Tool-chain using Keil, IAR and GCC. It also supports ARM mbed tool-chain for rapid prototyping and development using mbed’s IDE and tool-chain with an extensive range of open-source software libraries.

===== Getting started=====
===Blinky using Nordic SDK===
  *Follow the first part of this [[https://devzone.nordicsemi.com/tutorials/7/|tutorial]] 
  *Download and install [[https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads | GNU Arm Embedded Toolchain]]
  *Update the PATH variable(s) to include the GNU tools, something like: 

  C:\Program Files (x86)\GNU Tools ARM Embedded\7 2017-q4-major\bin

  *Test the path by typing 

  arm-none-eabi-gcc --version
 
  *Download and UNZIP in a convenient directory [[https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF5-SDK |nRF5 SDK Software Development Kit for the nRF51 Series and nRF52]] 
  *Download and UNZIP in a convenient directory the build tools from [[https://github.com/gnu-mcu-eclipse/windows-build-tools/releases | here]]
  *Update the PATH to include Build Tools directory, or copy the .exe files from .bin directory to blinky project directory
  *Set the toolchain path in **makefile.windows**, located in

  <SDK>/components/toolchain/gcc


  *It should be something like:

  GNU_INSTALL_ROOT := $(PROGFILES)/GNU Tools ARM Embedded/4.9 2015q3   // Toolchain path
  GNU_VERSION := 4.9.3  
  GNU_PREFIX := arm-none-eabi

  * Copy the .exe files from .bin directory to blinky project directory
  * Edit main.c, changing the GPIO line that is connected to the LED:

<code c++>
#include <stdbool.h>
#include <stdint.h>
#include "nrf_delay.h"
#include "boards.h"

int main(void)
{
    NRF_GPIO->DIRSET = (1 << 17);   // GPIO17 output,n-DAP LED

    /* Toggle LED */
    while (true)
    {
            NRF_GPIO->OUTSET = (1 << 17); // GPIO17 HIGH
            nrf_delay_ms(100);
            NRF_GPIO->OUTCLR = (1 << 17); // GPIO17 LOW
            nrf_delay_ms(100);
    }
}
</code>

  * Open command-line and change directory to

  <SDK>\examples\peripheral\blinky\pca10040\blank\armgcc
  
 

  *Run 

  make


  *Program the Flash Memory n-BLE with the created ''.bin'' file:

  F:\prj_soft\nRF5_SDK_12.3.0_d7731ad\examples\peripheral\blinky\pca10040\blank\armgcc\_build\nrf52832_xxaa.bin
\\
\\
===Blinky with mbed online compiler===

  * Select target ''Nordic nRF52-DK''
  * Create a blinky program like below
<code c++>
#include "mbed.h"

DigitalOut led1(P0_17);

// main() runs in its own thread in the OS
int main() {
    while (true) {
        led1 = !led1;
        wait(0.05);
    }
}
</code>
  * Program the Flash memory with the created ''.hex'' file  
\\
\\

=====Flash Memory Programming=====
====Programming with Nordic nRF52-DK board====
  * [[https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52-DK |nRF52-DK]] can be used as SWD programmer.\\
  * A DIY adaptation cable is needed.\\
{{n-pro-30-15.jpg?600}}\\
  * nRF52-DK appears as a USB DISK. Just drag and drop the file created from compiler to the disk.\\ 
  * nRF52-DK can use  both ''.hex'' and ''.bin'' files.\\
  * mbed on-line compiler produces ''.hex'', while GCC produces ''.bin'' and ''.hex''

  *BLE Beacon Humidity & Temperature Sensor
  *BLE Beacon Environmental Sensor
  *LoRa Sensor with BLE Commisioning
  *BLE simple Beacon for Localisation
