ESP32 Sensor Data Collection, Static Data After Sometime

Postby DJDhrub » Mon Feb 20, 2023 3:41 pm

I am trying to create a Room Environment Monitor System using ESP32, using TEMT600, AHT10, BMP280, MPU6050 sensor modules. Everything seems to work fine, but the data from BMP280 & MPU6050 stops coming. The BMP280 sensor gives me Temp of 180.73°C & Pressure of -127hPa. The MPU6050 gives similar static readings, Accelerometer -9.20, 0.00, -77.8 & Gyro -1194°, 0°, 0°. Both of them start giving static reading at same time but can vary between 5-60 min in my test.

I am also getting timeouts from BMP280 sometimes, may be that causing something?

I am attaching my code below, this is my first time trying with ESP32, so if someone help me out what's wrong with the code, that will be great. All of the sensors SDA are SDA GPIO 21, SCL GPIO 22.

I am pushing this data to Oracle Cloud, Tried doing it locally as well, faced similar issues but again when it's going to happen is uncertain, but when it happens happens for MPU6050, BMP280 at the same time.
