I want to connect the sensor to the STM32 board and read the measured value with uart, but I can't get the sensor value
So I tested with HAL_OK to see if the uart communication works well, but it says it can be transmitted, but it's not receiving, so I don't know what to do
I need to check with usb to uart module, but I don't have it
How can I get reception?
