Serial Monitor Output B-L475E-IOT01A Integration

[ishoe26]

Dear STM32 MC Support Team,

I recently purchased the B-L475E-IOT01A IoT development board for my project. I am currently trying to interface it with a BME668 environmental sensor and an AS7265x Spectral Triad sensor.

However, I am facing an issue while attempting to view the output through a serial monitor. Despite trying multiple serial monitoring tools, both online and offline, I am unable to receive any data output from the board.

I would greatly appreciate your guidance in resolving this issue. Any support regarding configuration, setup, or troubleshooting steps would be very helpful for my project.

Thank you for your time and assistance.

Have you used an oscilloscope to see if anything is happening at all?

Start with a simple, basic "Hello, world".

Continuously sending uppercase 'U' in a loop is good way to check baud rate, etc, using a 'scope...

Check schematics & User Manual to be sure you're using the correct pins.
