Hi. I am trying to use a hall sensor module with sim7080g.
The documentation is not very clear on connections for i2c device, according to pinout on website, I have SDA on pin 13 and SDL on pin 21. What is the address to use i2c device on these pins? The following sketch cannot find i2c device succesfully
if (! sensor.begin_I2C()) { // hardware I2C mode, can pass in address & alt Wire
//if (! sensor.begin_SPI(MLX90393_CS)) { // hardware SPI mode
Serial.println("No sensor found ... check your wiring?");
while (1) { delay(10); }
}
Serial.println("Found a MLX90393 sensor");
sensor.setGain(MLX90393_GAIN_1X);
// You can check the gain too
Serial.print("Gain set to: ");
switch (sensor.getGain()) {
case MLX90393_GAIN_1X: Serial.println("1 x"); break;
case MLX90393_GAIN_1_33X: Serial.println("1.33 x"); break;
case MLX90393_GAIN_1_67X: Serial.println("1.67 x"); break;

case MLX90393_GAIN_4X: Serial.println("4 x"); break;
case MLX90393_GAIN_5X: Serial.println("5 x"); break;
}
// Set resolution, per axis. Aim for sensitivity of ~0.3 for all axes.
sensor.setResolution(MLX90393_X, MLX90393_RES_17);
sensor.setResolution(MLX90393_Y, MLX90393_RES_17);
sensor.setResolution(MLX90393_Z, MLX90393_RES_16);
// Set oversampling
sensor.setOversampling(MLX90393_OSR_3);
// Set digital filtering
sensor.setFilter(MLX90393_FILTER_5);
}
void loop(void) {
float x, y, z;
// get X Y and Z data at once

Serial.print("X: "); Serial.print(x, 4); Serial.println(" uT");
Serial.print("Y: "); Serial.print(y, 4); Serial.println(" uT");

} else {
