Node: Need a sketch that works with Dragino LoRa Shield & Arduino Uno

I have used the 868 version just fine. There are some changes that you need to do that are specific for 915Mhz
Have a look here for tests and changes if you want 915Mhz to work OK
N.B. Only ABP works with the Dragino single channel gateway

1.Copy this code to your IDE and upload the sketch to your Arduino board:

There,you can also add below code to your sketch to check the current emission frequency:
Serial.println(LMIC.freq);


2.Edit "config.h"
change
   #define CFG_eu868 1
to
  #define CFG_us915 1

3.Edit "lmic.c",about on the line 760,
change
  void LMIC_disableChannel (u1_t channel) {
     if( channel < 72+MAX_XCHANNELS )
        LMIC.channelMap[channel/4] &= ~(1<<(channel&0xF));
  }

to

  void LMIC_disableChannel (u1_t channel) {
      if( channel < 72+MAX_XCHANNELS )
          LMIC.channelMap[channel/16] &= ~(1<<(channel&0xF));
  } 


4.Edit the "main.cpp" to "Set center frequency" on your Raspberry Pi.
change
   uint32_t freq = 868100000; //in Mhz! (868.1)
to
  uint32_t freq = 915000000; //in Mhz! (915.0)
