Description of defect

I am building a program with two APDS9930 I2C distance sensors.

Both use the same I2C slave address, so I decided to use 2 I2C peripherals (STM32WLE5 has 3 I2C available).

I2C_2 and I2C_3 work with any of the pin configurations available, but I2C_1 always fails.

Target(s) affected by this defect ?

STM32WLE5 (RAK3172)

Toolchain(s) (name and version) displaying this defect ?

Mbed Studio

What version of Mbed-os are you using (tag or sha) ?

Mbed OS 6.15

What version(s) of tools are you using. List all that apply (E.g. mbed-cli)

Mbed Studio 1.4.3

How is this defect reproduced ?

Trying to initialize an I2C configuration for I2C_1 using any of the available pin configurations for SDA/SCL (PA_10/PA_9, PA_10/PB_6, PB_7/PA_9, or PB_7/PB_6) always fails.
