    You have a blocking 10sec delay within each loop. It won't look at PA2 until PA3 is complete with its 10 second loop.

    You need better program logic here. Use a state machine or a callback to advance whatever it is you want to do. Increment a counter and when it reaches certain values, toggle pins at the appropriate time.

    What board?

    Is there a UART using these pins? Provide a schematic.
