How to manage power in stm32f4?

Question

C++ / C#

I want to organize such a scheme:
a touch sensor is connected to port D, vcc from bluetooth is connected to port C,
I read the state of the touch sensor, if the touch is activated, then I supply power to the bluetooth through port C

GPIO_SetBits(GPIOC, GPIO_Pin_11); // вроде даю 5 вольт на порт PC11 куда подключен vcc блютуза

but the bluetooth is not powered
, while the clocking of the port is turned on, and if you mark the LED in it, it will light up

Answer 1

Do you take off the power of the bluetooth directly from the foot of the mk ??? So you shouldn't do it.
The easiest way is through a transistor. Then the level of nutrition will not be a hindrance.

Answer 2

if the current of one output is not enough, then you can connect 2 or 3 outputs in parallel to increase the current
