Hello, I have strange trouble with my arduino mega. I'm trying to connect I2C gyroscope and I2C IMU to it, but wire.transmit() hangs. I connected same gyro to my arduino uno and run same programm and gyro worked. Yes I connected right: 21-SCL;20-SDA. What it can be?

Mistery: I2C not working, blink working

I also noticed that my imu already have pullup resistors
