can you make simplier like this repo?

Hi, you can check the tutorial here https://www.mischianti.org/2019/10/15/lora-e32-device-for-arduino-esp32-or-esp8266-specs-and-basic-usage-part-1/

And here the example https://github.com/xreef/LoRa_E32_Series_Library/blob/master/examples/sendReceiveTransparentTransmissionMessage/sendReceiveTransparentTransmissionMessage.ino

Hi I'm going to do a sample similar. Bye Renzo

@xreef thanks for inform waiiting updates

hope its comes soon make it simple as arduino-lora please

I think It's ok but untested

#include "Arduino.h"
#include "LoRa_E32.h"

LoRa_E32 e32ttl100(4, 5, 3, 7, 6);

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

    e32ttl100.begin();

}
long lastSendTime = 0;        // last send time
int interval = 3000;          // interval between sends

void loop() {
      if (millis() - lastSendTime > interval) {
        String message = "HeLoRa World!";   // send a message
        ResponseStatus rs = e32ttl100.sendMessage(message);

        Serial.println("Sending " + message);
        Serial.print("Sending state: ");
        Serial.println(rs.getResponseDescription());        // Check If there is some problem of succesfully send

        lastSendTime = millis();            // timestamp the message
        interval = random(2000) + 2000;    // 3-4 seconds
      }

    if (e32ttl100.available() > 1) {
        Serial.println("----------");
        ResponseContainer rc = e32ttl100.receiveMessage();

        if (rc.status.code != 1) {
            rc.status.getResponseDescription(); // if something goes wrong
        } else {
            Serial.println(rc.data); // if It's all ok
        }
    }
}

i just oredered devices x4 on the way, i wonder is it have control about spread spectrum or coding rate or etc can we config ?

[xreef]

It's quite simple to config, you have all examples and parameters in this article https://www.mischianti.org/2019/10/29/lora-e32-device-for-arduino-esp32-or-esp8266-configuration-part-3/ Bye Renzo
