Pin out for lorawan and bme280 example with cubecel

#1

in this code what is the pin out for CubeCell 1 / 2AA Node

I have tried with pins 36 and 37 -39 and 40 for scl and sda and the sensor does not send information

as i see it must be 39 and 40 pins, because of Wire.h what are for I2C connection, check if the pins what connected to htcc-ab02a connected to same name pins of sensor

#3

also you can try use regular example without LoRa, to easily debug

#4

Yes, they are on pins 39 and 40, I have used this simpler code and if it works,

#include “Seeed_BME280.h”
#include <Wire.h>

BME280 bme280;

void setup()
{
pinMode(Vext, OUTPUT);
digitalWrite(Vext, LOW);
delay(500);

Serial.begin(115200);
if(!bme280.init()){
Serial.println(“Device error!”);
}
}

void loop()
{
float pressure;

//get and print temperatures
Serial.print("Temp: ");
Serial.print(bme280.getTemperature());
Serial.println(“C”);//The unit for Celsius because original arduino don’t support speical symbols

//get and print atmospheric pressure data
Serial.print("Pressure: ");
Serial.print(pressure = bme280.getPressure());
Serial.println(“Pa”);

//get and print altitude data
Serial.print("Altitude: ");
Serial.print(bme280.calcAltitude(pressure));
Serial.println(“m”);

//get and print humidity data
Serial.print(“Humidity: “);
Serial.print(bme280.getHumidity());
Serial.println(”%”);

delay(1000);
}

but with the code to connect to lorawan it does not recognize the sensor

#5

but with the code to connect to lorawan it does not recognize the sensor

It sends in serial this?

if(ENABLE_SERIAL){
Serial.println(“Device error!”);
}

or it just sends nothing by lora

#6

firstly, what do i, thats encrease delay here to gett the device more time to init

#7

it does not lift the sensor with that code, it does not send information

the sensor works, I have tested it with the second code that I paste
sensor%202

I’m using the test code, it should work

Minor difference in the sample you were testing the sensor with you are using the BME280 lib. in the code you are using for the Lora example you are using the BMP 280.
