When using LoRa, I have tried to program 2 sensors, which must send the data to the receiver, however when sending the data the sensors do not work.
The sensors used are: BME280 and CCS811
This code is in which when sending the data, the sensors stop working:

Serial.println(F("SSD1306 allocation failed"));
for (;;); // Don't proceed, loop forever
}
display.clearDisplay();

}
void startSensors() {
I2Cone.begin(SDA, SCL, 100000);
bool status1 = bme.begin(0x76, &I2Cone);
if (!status1) {
Serial.println("Could not find a valid BME280_1 sensor, check wiring!");
while (1);
}
Serial.println("CO2, TVOC");
if (!ccs.begin()) { // Intentar inicializar el sensor

if (ccs.available()) { // Si el sensor está disponible
if (!ccs.readData()) {

sendReadings();

}
This code is without sending data, in which the sensors do work:
//Libraries for BME280
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>
#include "Adafruit_CCS811.h"
Adafruit_CCS811 ccs;
TwoWire I2Cone = TwoWire(1);
Adafruit_BME280 bme;
float temperature = 0;
float humidity = 0;
float pressure = 0;
float co2 = 0;
void setup() {
Serial.begin(115200);
I2Cone.begin(SDA, SCL, 100000);
bool status1 = bme.begin(0x76, &I2Cone);
if (!status1) {
Serial.println("Could not find a valid BME280_1 sensor, check wiring!");
while (1);
}
Serial.println("CO2, TVOC");
if (!ccs.begin()) { // Intentar inicializar el sensor
Serial.println("¡No se ha podido inicializar el sensor! Por favor, comprueba el cableado.");
while (1);
}
while (!ccs.available()); // Esperar a que el sensor esté preparado
}
void loop() {
if (ccs.available()) { // Si el sensor está disponible
if (!ccs.readData()) { // Cuando haya datos
co2 = ccs.geteCO2(); // Obtener y enviar el nivel del CO2 por el puerto serie
temperature = bme.readTemperature();
humidity = bme.readHumidity();
pressure = bme.readPressure() / 100.0F;
Serial.print("CO2:");
Serial.println(co2);
Serial.print("Temp:");
Serial.println(temperature);
Serial.print("Hum:");
Serial.println(humidity);
Serial.print("Press:");
Serial.println(pressure);
}
else {
Serial.println("ERROR!"); // Cuando ocurra un error
while (1); // El dispositivo deja de funcionar
}
}
delay(2000); // Hacer la medida cada 2 segundos(2000ms)
}
Here the circuit:
