I am trying to create a software serial connection between Arduino Uno & Adafruit Feather M0 Bluefruit LE.

I am getting the following error in the M0 sketch:

Arduino: 1.8.1 (Windows 10), Board: "Adafruit Feather M0"

atcommand:60: error: 'SoftwareSerial' does not name a type

 SoftwareSerial bluefruitSS = SoftwareSerial(BLUEFRUIT_SWUART_TXD_PIN, BLUEFRUIT_SWUART_RXD_PIN);


atcommand:62: error: 'bluefruitSS' was not declared in this scope

 Adafruit_BluefruitLE_UART ble(bluefruitSS, BLUEFRUIT_UART_MODE_PIN,


exit status 1
'SoftwareSerial' does not name a type

Here are the modifications I did to the atcommand sketch (in Adafruit BluefruitLE nRF51 library) before uploading to the M0:

#include <Arduino.h>
#include <SPI.h>
#if not defined (_VARIANT_ARDUINO_DUE_X_) && not defined (_VARIANT_ARDUINO_ZERO_)
  #include <SoftwareSerial.h>

#include "Adafruit_BLE.h"
#include "Adafruit_BluefruitLE_SPI.h"
#include "Adafruit_BluefruitLE_UART.h"

#include "BluefruitConfig.h"

// Create the bluefruit object, either software serial...uncomment these lines

SoftwareSerial bluefruitSS = SoftwareSerial(BLUEFRUIT_SWUART_TXD_PIN, BLUEFRUIT_SWUART_RXD_PIN);

Adafruit_BluefruitLE_UART ble(bluefruitSS, BLUEFRUIT_UART_MODE_PIN,

/* ...or hardware serial, which does not need the RTS/CTS pins. Uncomment this line */

/* ...hardware SPI, using SCK/MOSI/MISO hardware SPI pins and then user selected CS/IRQ/RST */

/* ...software SPI, using SCK/MOSI/MISO user-defined SPI pins and then user selected CS/IRQ/RST */
//                             BLUEFRUIT_SPI_MOSI, BLUEFRUIT_SPI_CS,
//                             BLUEFRUIT_SPI_IRQ, BLUEFRUIT_SPI_RST);

I tried to comment the if statement before #include <SoftwareSerial.h>, I got the following error:

Arduino: 1.8.1 (Windows 10), Board: "Adafruit Feather M0"

C:\Users\hadeel\AppData\Local\Temp\arduino_modified_sketch_612073\atcommand.ino:18:30: fatal error: SoftwareSerial.h: No such file or directory

   #include "SoftwareSerial.h"


compilation terminated.

exit status 1
Error compiling for board Adafruit Feather M0.

What is the problem?
