希望可以解决[quote="antonio50, post:1, topic:3779, full:true"]
I have used BluetoothLE
http://iot.appinventor.mit.edu/#/bluetoothle/bluetoothleintro
I ask for advice to do (in the simplest way possible) a scan of the Bluetooth signals and extract something like:
(which blocks is best to use)
"24: 4B: 03: 9C: 39: 0B": - 98, "5F: D7: 13: 43: 76: 28" - 97 ", D0: 4F: 7E: 12: C4: 22": - 97
by inserting them into a label
Thanks to those who want to indicate it

First of all, I don't understand Chinese. Please change the language to English so we could help you.
You need to wait for a few seconds after start scanning, to list the found device addresses. The result would be list of string elements that can be visualized with a list picker... After picking one, you need to split the selected one on white spaces and select the first index (MAC name rssi) to connect.
In this example I filter all devices without a name from the list.
