I2C failure on "substitute" BMP280

Other Hardware Sensors
4

I wired it up per https://startingelectronics.org/tutorials/arduino/modules/pressure-sensor/

It's the same as for the actual BMP280 for the sensor.
But from a Vroom esp32 using pins D21-SDA and D22-SCL.

Scanner code

```
// https://www.circuitschools.com/interfacing-16x2-lcd-module-with-esp32-with-and-without-i2c/
#include <Wire.h> //include Wire.h library
 
void setup()
{
  Wire.begin(); // Wire communication begin
  Serial.begin(9600); // The baudrate of Serial monitor is set in 9600
  while (!Serial); // Waiting for Serial Monitor
  Serial.println("\nI2C address Scanner CircuitSchools.com");
}
 
void loop()
{
  byte error, address; //variable for error and I2C address
  int devicecount;
 
  Serial.println("Scanning...");
 
  devicecount = 0;
  for (address = 1; address < 127; address++ )
  {
    // The i2c_scanner uses the return value of
    // the Write.endTransmisstion to see if
    // a device did acknowledge to the address.
    Wire.beginTransmission(address);
    error = Wire.endTransmission();
 
    if (error == 0)
    {
      Serial.print("I2C device found at address 0x");
      if (address < 16)
        Serial.print("0");
      Serial.print(address, HEX);
      Serial.println("  !");
      devicecount++;
    }
    else if (error == 4)
    {
      Serial.print("Unknown error at address 0x");
      if (address < 16)
        Serial.print("0");
      Serial.println(address, HEX);
    }
  }
  if (devicecount == 0)
    Serial.println("No I2C devices found\n");
  else
    Serial.println("done\n");
 
  delay(5000); // wait 5 seconds for the next I2C scan
}
```
