shorting pins 5 and 6 while RPI is on

[petergellert03]

Hello, I know that if I short pins 5 and 6 when the RPI is asleep it will wake up, so I've connected a capacitive touch button(with a 3v3 vcc) on it, and I've got it waking up. The turn off will be performed by the user from a locally hosted Apache2 server (part of a bigger project, as we all are ).

Now all I want to know, if I accidentally short it while the PI is awake - because it is a capacitive "button" and it doesn't needs to be completely touched, if put my hand close (2-3 mm) it does the magic - will anything bad happen?

Thanks in advance

By default shorting pins 5 & 6 will do nothing on a running RPi.

In order to add shutdown function to pin 5 & 6 you would have to add dtoverlay=gpio-shutdown to /boot/config.txt -OR- create and run a script to do shutdown or some other function.

if we use the "shut down" in menu can we still just jump 5/6 to wake ,,as opposed to unplug/plug to restart?

You COULD do this, but Raspbian now has gpio-shutdown built in.

NOTE the pin 5/6 thing is an anachronism. Now all Pi models have an accessible RUN pin it is unnecessary, and doesn't work if gpio-poweroff is used.

Unless something has changed, if you ground the RUN pin while the Pi is running, it will do a hard reboot, not a good thing.
Using the pin 5 and 6 method is a better way to go IMHO. Nothing happens on a button press if the Pi is already running unless you add the dtoverlay=gpio-shutdown to /boot/config.txt. No RUN no foul. Other than maybe messing up your i2c coms for a second.

Unfortunately, it requires soldering. Not everybody can solder, and even some of those of us who can are reluctant to solder on a board they have not made from scratch (as in, what if I mess up and kill my RPi).

Fishing line makes a good alternative to solder.

It is, but I was serious. Thread the line through the holes, push in some wires for a friction fit connection.

There's several posts about it in this very forum, mostly from before the Pi0WH existed.
For example:

Eugene ‘thirtytwoteeth’ Andruszczenko (of Game Boy Zero – Handheld Edition fame) posted a neat idea to help your Raspberry Pi Zero take jumper wires without soldering. He threaded fishing line through the 40 hole header, making an interference fit for male header pins. I tried it with 0.38 mm Trilene, which worked rather well.

never tried this but have a look

LOL. That would not help anyone with the RUN thing, which is not on the header. At any rate, as others have pointed out, shorting RUN would do a hard reboot, like turning the power off and on, something to be avoided.
