@watson Thank you replying.
I' m not sure how to update the library.
I need to use the MPU9250 to monitor a pumps vibrations.

@0x1abin Hi, please can you explain to me how this fixed the issue. I am struggling with the same thing. I am very new to this. I have followed all the instructions but i dont know how to upload the other I2c onto the m5stack.
I'm sure I'm missing something...
