Hi Guys,
LC76F I2C problem

I am having problems with I2C of LC76F. For UART it works fine.
. When I use the ESP32 to scan I2C, I cannot receive any information returned (the program stops working). When I disconnect the LC76F from the ESP32, the program can scan the available sensors.

Is there any information on how the LC76F uses I2C. How can I use its I2C? Is it necessary to update the firmware? and how?

Thank!!
