I would like to detect present with my iphone, i’m thinking with Ibeacon.

I did see the bluetooht binding has beacon support

beacon	A Bluetooth device that is not connected, but only broadcasts annoucements.

My question is, can i use the bluetooth inside the Raspberry Pi 3b or do i need a USB dongle. if so. What dongle works with this binding?

I use

With this you can use the RPI build in bluetooth. Depending on location, walls, furniture, etc… the range will be limited.

You can also use a USB dongle, either attached to the same RPI or on a second RPI that’s placed in a different location. There are several dongles that will work, see the link to find one that you may like.
