How to Send Message use JSON Format ? #1

How to Send Message use JSON Format ? Hello , Can you help me ? How to solve this Question ?

xreef commented 4 years ago

Hi taurushappy, you can use ArduinoJSON library, (I'm going to publish a post on how to use It).

You can 

  DynamicJsonDocument doc(512);

  // Set the values in the document
  doc["energyLifetime"] = 21698620;
  doc["energyYearly"] = 1363005;

String buf;
serializeJson(doc, buf);

ResponseStatus rs = e32ttl.sendMessage(buf);

Remember you have a size limit on message size of the lora E32.

The code is untested, but I think It can be usefully to understand.

Tell me if It's ok.

Bye Renzo

HI !    first, thanks  for your help !    I try this ,the code can work ,but I don't know it have some problem in my test ,it only work one time,send  Message one time ,then stoped!     this  is  my test code : 

 #include "Arduino.h"

include "LoRa_E32.h"

include <DHT.h>

include <ArduinoJson.h>

define DHTPIN 4

define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

DynamicJsonDocument doc(512);

// ---------- esp8266 pins -------------- //LoRa_E32 e32ttl(D2, D3, D5, D7, D6); //LoRa_E32 e32ttl(D2, D3); // Config without connect AUX and M0 M1

void setup() {      Serial.begin(9600);   delay(500);

  // Startup all pins and UART   e32ttl100.begin();   dht.begin();

  Serial.println("Hi, I'm going to send message!");

  // Send message   ResponseStatus rs = e32ttl100.sendMessage("Hello, Taurus!");   // Check If there is some problem of succesfully send   Serial.println(rs.getResponseDescription()); }

int i = 0;

void loop() {

  float h = dht.readHumidity();   // Read temperature as Celsius (the default)   float t = dht.readTemperature();   // Read temperature as Fahrenheit (isFahrenheit = true)   float f = dht.readTemperature(true);

  // Check if any reads failed and exit early (to try again).   if (isnan(h) || isnan(t) || isnan(f)) {     Serial.println(F("Failed to read from DHT sensor!"));     return;   }

  // Compute heat index in Fahrenheit (the default)   float hif = dht.computeHeatIndex(f, h);   // Compute heat index in Celsius (isFahreheit = false)   float hic = dht.computeHeatIndex(t, h, false);

  Serial.print(F("Humidity: "));   Serial.print(h);   Serial.print(F("%  Temperature: "));   Serial.print(t);   Serial.print(F("°C "));   Serial.print(f);   Serial.print(F("°F  Heat index: "));   Serial.print(hic);   Serial.print(F("°C "));   Serial.print(hif);   Serial.println(F("°F"));

       delay(1000);     

   doc["temperature"]=t;    doc["humidity"]=h;    String buf;    serializeJson(doc,buf);    ResponseStatus rs = e32ttl100.sendMessage(buf);

     Serial.println(rs.getResponseDescription());

  delay(1000);

}

Hi I check your sketch and seems quite ok.

But I think you must add AUX pin or put a pull up resistor on It, with no AUX not work for me, but with aux I have a correct send.

And Arduino Json have some problem on serialize on String

    return (int) &v - (__brkval == 0 ? (int) &__heap_start : (int) __brkval);

I tested and works correctly, I close issue but I wait feedback. Thanks and bye Renzo

taurushappy commented 4 years ago 
 Thanks  your help solve the problem with send message use json !  I am a Chinese student，and I want to know :
  1. how to buy your create arduino shield without use 4.7k resister when use LoRa E32? and how much the your create arduino shield ?
  2. how to find the passage about "LoRa E32 device for Arduino, esp32 or esp8266: real example ad WeMos D1 shield"
xreef commented 4 years ago

Hi taurushappy, Why don't you want to use 4.7k resistors? You can try with similar different value, but datasheet advise 4.7k. The price isn't relevant, I don't sell the shield, I give the possibility to buy from productor of PCB the PCB with my schema. I add the link here on github, but It exist already on my site. Bye Renzo

 Thanks !     If  I want  to  make  data terminal unit   product in lot project , i couldn't use  breadboard , it is too large! so I need small and convenience  pcb instead !
