Hi Renzo,

thank you for your quick answer!

I think it was incorrect copy paste, but I think description here is incorrect. Particularly chapter Fixed transmission “So first, we must set M0 to LOW and M1 pin to HIGH to enter on program/sleep mode and set the correct address and fixed transmission flag.” Based on documentation it should be M0 + M1 on HIGH.

As you suggested I have updated wiring for module programming. Everything was working, but afterwards I have started playing with RSSI. From response container I was just able to print out RSSI value, but not anymore rc.data (always blank).

Due to that I have started playing with modules and it seems I have somehow f*cked it up.
So I have started from scratch (transparent transmission config upload, transparent transmission example, M0 + M1 on LOW, AUX connected).

Code example

#include "Arduino.h"
#include "EByte_LoRa_E220_library.h"
#define FREQUENCY_868 <- with our without
 
// ---------- esp32 pins --------------
LoRa_E220 e220ttl(&Serial2, 25, UART_BPS_RATE_9600); //  RX AUX M0 M1

void setup() {
  Serial.begin(9600);
  delay(5000);
 
  Serial.println("Hi, I'm going to send message!");
 
  // Startup all pins and UART
  e220ttl.begin();
 
  // Send message
  ResponseStatus rs = e220ttl.sendMessage("Hello, world?");
  // Check If there is some problem of successfully send
  Serial.println(rs.getResponseDescription());
}
 
void loop() {
    // If something available
  if (e220ttl.available()>1) {
      // read the String message
    ResponseContainer rc = e220ttl.receiveMessage();
    // Is something goes wrong print error
    if (rc.status.code!=1){
        rc.status.getResponseDescription();
    }else{
        // Print the data received
        Serial.println(rc.data);
    }
  }
  if (Serial.available()) {
      String input = Serial.readString();
      ResponseStatus rs = e220ttl.sendMessage(input);
      Serial.println("Response :"  +  rs.getResponseDescription());
  }
} 

It is running on identical ESPs with identical wiring.
I’m just curious regarding one thing. As M0 + M1 is on LOW, I assume I can not get correct configuration, right?

I’m asking due to

HEAD : 2 E5 DA
 
AddH : EB
AddL : D2
 
Chan : 0 -> 862MHz

Thank you in advance!
