Serial Port issue
Please share snippet of your code for better understanding? Did you declared Serial.begin()??

What are some good online simulators with free access to practice embedded systems
Try Wowki and Tinkercad.

Ok yes please

Thank you see if you can suggest some good sensors that's more than enough,I can train my model with raw data and create a huge sample before even start testing explicitly. SR04 is too basic also it cannot be used on contact basis (can't dip this anywhere)

Hey Thanks for reply , For now lets say I am just concerned about detergent and water adulteration I am not concerned about concentration but more of a presence and should be an optical way to do it. That's why I asked if any1 has used any sensor for that use case.

Can anyone suggest how to design custom hardware for stm32 microcontroller. ie. designing bare minimal hardware of microcontroller to get started with it.
https://youtu.be/C7-8nUU6e3E This is the link to a guy Phil's Lab he has deigned a custom board Around an STM32 MCU watch this video you will learn a TON also explore his channel he has some videos on Advance topics so watch and learn.

So yes I want you to hook up the TX pin to an oscilloscope and check and decode the data coming start by sending "Hello" from MCU and see what you are getting. OR If you don't want to get into that much trouble take a working USB to Serial converter that are dirt cheap and easily available in marketRead more

OR
If you don’t want to get into that much trouble take a working USB to Serial converter that are dirt cheap and easily available in market connect your TX line to RX for that converter and see if you are getting right data, If yes then the issue is with the IC if No then the issue is with the data that is being transmitted (MCU).
Either way you will have your answer.
Also before starting all this check the pins pf QFN package if they have been soldered properly ,Cold solder joint can also cause this is sort of issue.
Use a thin pin multimeter for it.
Let me know your progress.

Well desoldering and soldering QFN package is not a big deal if you have a soldering station. Apart from that if circuit is working and this issue is just on this board it seems like a IC issue particularly but I Can't tell until you probe TX line and update what you are getting.

Also if circuit is fine then it might be IC issue swap with another IC and check if problem still persist.
