  Appcon wireless LoRa module RF1276 perform a good range test in the coast area. It get the 10km in Italy.

  @LawrenceGrif I directly send mail to Appconwireless. The sales manager is a kindly guy named Forbe. He is passionate and hard-working.

  I know Dorji DRF1278DM. Dorji is one of distributors of Appconwireless RF module. DRF1278DM don't have shields. The anti-jamming ability is worse than the RF1276 as I have tested.

  The module can make the configuration via UART-TLL converter by RF tool. It is objective.
  Also it supports the AT command via serial port.

  Hi Gordon,the relevant commands are used for parameter setting. For the serial communication, the UART parameter need to be compatible for both espruino and module. The belowing code is for TX and RX between two LoRa modules RF1276 and espruino.

  ---

  // TX
  
  // Alternate sending 1 and 2 to make RX expruio blink
  
  const int buttonPin = 10;     // the number of the pushbutton pin
  
  int buttonState = 0;         // variable for reading the pushbutton status
  
  
  void setup() {                
   Serial.begin(9600);   // it depend on serial port of RF1276, we set the serial port baud rate 9600bps
  
  }
  
  void loop() {  
   buttonState = digitalRead(buttonPin);
  
   // check if the pushbutton is pressed.
   // if it is, the buttonState is HIGH:
   if (buttonState == HIGH) {     
     // turn LED on:    
     Serial.println("1"); 
   } 
   else {
     // turn LED off:
     Serial.println("2");
   }
   delay(100); 
  
  }
  
  _____________________
  
  // RX
  
  int led = 13;
  
  void setup() {                
   pinMode(led, OUTPUT);
   Serial.begin(9600);
  }
  
  
  void loop() {
  
   if (Serial.available()){
     char input = Serial.read();
     switch (input){
     case '1':
       digitalWrite(led, HIGH);  
       delay(100); 
       break;
     case '2':
       digitalWrite(led, LOW); 
       delay(100); 
       break;
     }
   }  
   else // blinks if there is no serial connection available 
   {
     digitalWrite(led, HIGH);
     delay(200);
     digitalWrite(led, LOW);
     delay(200);
   }
  }

  Hi Gordon,
  I am not the guy which make the spam. I am electronical hobby. The link that i provide is a kind of UART transparent module. very simple coding to integrate with Espruino or Arduino.
  For the coding, you can check this link:
  http://eclipsesource.com/blogs/2012/10/1­7/serial-communication-in-java-with-rasp­berry-pi-and-rxtx/
  The module is cost-effective compared to other vendors. The technical guys are kindly to help us for debugging. Click this for more

  Hi, Do you need UART port module? They are highly integrate. Please check this module.

  Please try this module. I have tested in the wild field. The RF range is up to 10km.

  The lora module is really amazing performance. I have tested the LoRa module based on SX1276. The working range is up to 10km through several woods. Though the manufacture of the module claim the range is only 5km. The below link is the detail of LoRa.
