I wonder did any of you use a button instead of that bulky header for BOOT on ST32 devices (Blue Pill, etc)? My guess is it can be put in BOOT mode using the same sequence as for ESP. In other words, with two buttons, I could achieve the same as with the header. The question is: HOW?
On STM32, BOOT should be LOW when STM32 is doing things. When HIGH it should go in BOOT mode. That means I should make it something like this:
What do you think?
I think that circuit is defective. 
is not as good as reading the documentation
What would not be defective? 
This is the circuit for the reset button on Blue Pill.
Guess is a guess. 
In the documentation, I didn't find the circuit for this. Maybe I didn't read enough. That is why I am asking the one who read well enough. 
What upload method are you using? Serial or ST-Link?
Serial.
That deleted post is ... great. Thank you. I will try hammer next time.
You could just use a SPDT switch, attach it to the 3 pin headers. Or make your life easy, get an ST-Link.
No it isn't...

Button seems better looking on board.
LOL. My bad. Made it in a hurry, didn't check it as I should.
Ok, so, the circuit from the link you provided. That is the one I "thought" I pointed. Should it be the solution? Don't believe no one made it so far.
Are you planning on re-designing and producing a new Blue Pill? It has no USB-serial converter on board so the serial upload is a wire jumper mess anyway...
Nope. I just want to try a thing or two. Learn along the way.
But, does it really matters what I want to do? Does it make any change? I think it is purely my business.
It is not STM32F1 in the first place, but STM32F0. The procedure is the same if I am not wrong.
Wow, sorry to intrude on your privacy. Good luck and enjoy STM32 coding. Also welcome to my ignore list.
LOL. So childish, almost pathetic. Not sure should I smile or should I cry?
That post you erased would give more sense for this conversation. On your bad, I read it. Whole.
Have you ever tried to go out of the room? There is a world out there.
