Hi,
I’m trying to use the LMIC-Node project with Platformio and am not able to get any i2c sensors working.
I’m testing with a BMP280. I’ve tried an i2c scanner and can see the sensor on 21/22 or 4/15 however I haven’t been able to get readings from it with any library.
I’ve tried the following libraries
None of them can detect the sensor.
Here’s the example code for the BMP280_DEV project.
// BMP280_DEV - ESP32, I2C Communications, Default Configuration, Normal Conversion, User-Defined Pins
//////////////////////////////////////////////////////////////////////////////////////////////////////////
#include <BMP280_DEV.h> // Include the BMP280_DEV.h library
float temperature, pressure, altitude; // Create the temperature, pressure and altitude variables
BMP280_DEV bmp280(21, 22); // Instantiate (create) a BMP280 object and set-up for I2C operation on pins SDA: A6, SCL: A7
void setup()
{
Serial.begin(9600); // Initialise the serial port
bmp280.begin(); // Default initialisation, place the BMP280 into SLEEP_MODE
bmp280.setTimeStandby(TIME_STANDBY_2000MS); // Set the standby time to 2 seconds
bmp280.startNormalConversion(); // Start BMP280 continuous conversion in NORMAL_MODE
}
void loop()
{
if (bmp280.getMeasurements(temperature, pressure, altitude)) // Check if the measurement is complete
{
Serial.print(temperature); // Display the results Serial.print(F("*C ")); Serial.print(pressure); Serial.print(F("hPa ")); Serial.print(altitude); Serial.println(F("m"));}
}
Any suggestions to get this basic example working? Hopefully once I get one of these libraries working I can get it working in LMIC-Node as well.
Thanks!
