Error amb_ard_pin_check_fun. Incorrect pin: 26 keeps showing in serial monitor

I keep getting the following error repeatedly in the serial monitor:

Error amb_ard_pin_check_fun. Incorrect pin: 26

I’m using the following pins in my project: PA27, PA13, PB3, PA12, PA26, and PA25.
(PA27, PA13, PB3, PA12 for buttons and PA26, and PA25 for SDA , SCL)
This issue did not occur in version 3.1.5 — it only started happening after I updated to a newer version.
How can I fix this issue?

It seems like the error Error amb_ard_pin_check_fun. Incorrect pin: 26 occurs when I use Wire.begin().

Hi @NOOB,

May I check what sensor and example are you using? Which SDK version are you using now?

Can you test by using the default I2C examples, will you be able to use the I2C interface?

Can you check your hardware connections?

Thank you.
