ESP32 | FLUTTER | BLE - MPU6050, Rotate your 3d object in the app
In this video, I show you how to use the MPU6050 Accelerometer and Gyroscope sensor with the ESP32. First, I will explain how the MPU6050 works and how to read the data from it, and then we will make a flutter application for a 3D visualization of the sensor orientation.
MPU6050 IMU
ESP32 Wemos Lolin32 lite
**How to fix this
error: 'Trash' was not declared in this scope
getFIFOBytes(Trash, (uint8_t)RemoveBytes);
^
exit status 1
Go to your Arduino library folder, open the folder MPU6050.
Now you can find MPU6050.h. After line# 432, you need to add this,"#define BUFFER_LENGTH 32".

**Flutter App
Add permissions for Bluetooth
We need to add the permission to use Bluetooth and access location:
Android
In the android/app/src/main/AndroidManifest.xml let’s add:
uses-permission android:name="android.permission.BLUETOOTH"/
uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /
uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/
application
IOS
In the ios/Runner/Info.plist let’s add:
dict
key NSBluetoothAlwaysUsageDescription /key
string Need BLE permission /string
key NSBluetoothPeripheralUsageDescription /key
string Need BLE permission /string
key NSLocationAlwaysAndWhenInUseUsageDescription /key
string Need Location permission /string
key NSLocationAlwaysUsageDescription /key
string Need Location permission /string
key NSLocationWhenInUseUsageDescription /key
string Need Location permission /string
