ESP32 Forum

Hi.
I have a question about the LORA module with LILYGO ver. T3 V1.6.1.
I cannot get LORA to work.
On the board I have esp version ESP32-PICO-D4.

Below I paste the connections from datasheet T3 V1.6.1 between esp and lora:

IO23=RESET
IO18=NSS/SEL
IO5=SCK
IO27=MOSI/SDI
IO19=MISO/SDO
IO26=DI0/IO0

Here I am attaching the pinout of the esp modules:

IO18=PIN 35
IO23=PIN 36
IO26=PIN 15

This is my code and the pins I have configured according to the documentation but it still doesn't work.
(Source: https://how2electronics.com/esp32-lora- ... -receiver/)

#include <Adafruit_GFX.h>
#include <LoRa.h>
#include <SPI.h>

#define ss 35
#define rst 36
#define dio0 15

int counter = 0;

void setup()
{
Serial.begin(9600);
while (!Serial)
;
Serial.println("LoRa Sender");

LoRa.setPins(ss, rst, dio0); // setup LoRa transceiver module

while (!LoRa.begin(433E6)) // 433E6 - Asia, 866E6 - Europe, 915E6 - North America
{
Serial.println(".");
delay(5000);
}
LoRa.setSyncWord(0xA5);
Serial.println("LoRa Initializing OK!");
}

void loop()
{
Serial.print("Sending packet: ");
Serial.println(counter);

LoRa.beginPacket(); // Send LoRa packet to receiver
LoRa.print("hello ");
LoRa.print(counter);
LoRa.endPacket();

counter++;

delay(10000);
}

The terminal gets it:

What am I doing wrong?
/Thanks.

If the schematic/datasheet says that a lora function is attached to a esp pin on the pcb, that means there is a wire physically connecting them- you can't just redefine that.
pins >33 are input only, so you can't use them for something like a select or reset line (they can be used for MISO).
