i have a problem getting my end device data to be sent frequently by it self to the TTN server , the end device send the data only one time after its turend on or after lunching the serial monitor and stop sending after that …
so this is my hardware …

67727573_2096139644021914_1710984670008573952_n End%20device

am using dragino gateway LG01-N 915MHz and for the end device am using dragino lora GPS shield 915MHz + arduino uno .

and this is the arduino sketch using

github.com

goodcheney/Arduino-Profile-Examples/blob/patch-4/libraries/Dragino/examples/LoRa/LoRaWAN/LoRa_GPS_Shield_TTN

#include <lmic.h>
#include <hal/hal.h>
#include <SPI.h>
#include <SoftwareSerial.h>
#include <TinyGPS.h>
TinyGPS gps;
SoftwareSerial ss(3, 4); // Arduino RX, TX to conenct to GPS module.

static void smartdelay(unsigned long ms);

unsigned int count = 1;        //For times count


String datastring1="";        
String datastring2="";        
String datastring3="";
char datasend[20];     //Used to store GPS data for uploading

char gps_lon[20]={"\0"};  //Storage GPS info
char gps_lat[20]={"\0"}; //Storage latitude

This file has been truncated. show original

and this is the current gateway sitting am working with

Gateway

any thoughts ??

I have also the same error!

Appreciate that the Dragino Gateway described at the start of this thread and the program code they provide for one of thier shields are not compliant with the requirements ofor the TTN network.

So the users of this TTN forum probably have no experiences with that setup, so difficult to assist.

May i have the library?

If its a ‘library’ for the Dragino, then TTN would not be expected to hold a copy.

Pop across to Dragino support and ask them.
