B4J Question I2C Remote I/O error :(

[Alessandra Pellegri]

Hello, I am doing experiments with this example over RPi3:
https://www.b4x.com/android/forum/threads/simple-text-based-ssd1306-driver.63003/

But I get the error in attachment.

b4j-bridge.jar is started with sudo and I2c is enabled. I can see i2c-1 under /dev folder.

What can I do ?

Thank you very much.

Solved ! I had inverted SDA with SCL pins.
