MPU6050_DMP works in 1.0.6, 2.0.0 , but fail to initialize I2C interface with v2.0.1 , 2.0.2

Board

NodeMCU-32S

Device Description

ESP32 (NodeMCU-32S)

Hardware Configuration

GPIO 18 & 19 I2C connected to MPU6050

Version

v2.0.2

IDE Name

ArduinoIDE

Operating System

Ubuntu20.04 & Win11

Flash frequency

80MHz

PSRAM enabled

no

Upload speed

921600

Description

MPU6050 library support MPU6050 DMP
which provides pitch-yaw-roll, and quaternions.

It failed at Initialing I2C Interace,
both examples from the library MPU6050_DMP.ino & MPU6050_raw.ino failed,
but they works fine in v2.0.0

Sketch

// initialize device
    Serial.println(F("Initializing I2C devices..."));
    mpu.initialize();

Debug Message

No error message, just hang at Initializing I2C devices...

Other Steps to Reproduce

MPU6050 works in Project Tasmota. We use our own driver for the MPU6050.
So the library you use is not compatible.

[rkuo2000]

I use MPU6050 library for MPU6050 DMP output, because it can provide the stable pitch-roll-yaw, and quaternions.

I would open a issue there.

that library's code is all broken. Calling beginTransaction, followed by requestFrom and endTransaction is NOT a valid code! beginTransaction and endTransaction are to be used ONLY when writing. The fact that is works on other MCUs with more basic I2C peripherals and not RTOS environments, does not make the code valid.

BTW, my robot design use MPU6050 DMP for AHRS and ESP32 v2.02 for microROS, I really like to see them work together,
let me review MPU6050 DMP I2C coding, and see if I can fix it to make them compatible.

I think we are not able to help here, the problem is in mentioned Library.
