Hi, 

I can get the phone local IP address using Taifun´s Wifi Extension Manager, and also its MAC Address.  Let´s say IP it´s 192.168.1.aaa.

Is there a way to scan all local network addresses (In my example, from 192.168.1.1 to 192.168.1.255) with the goal of getting the MAC Address for each IP address that has a device connected?

Can´t see how. 

Thanks!

Bertu

Difficult, right?  :)

I would need to build a simplified version of FING (free app @ Google Play), retrieving only a list of found IP addresses, MAC Addresses, and ideally uPnP names.

Any ideas are welcome!

Hi,
You can't do this in base App Inventor. You essentially want to build an ARP client (Address Resolution Protocol). 
In Unix (Mac/Linux), you can use "netstat" to get a lot of this information. 
You would need an extension for this, and unfortunately, I don't know of any that have been built that could do this.

Hola Pablo, gracias por la felicitación en el envío de la extensión de Install. No consigo ver las MAC de una red, lo he intentado de estas formas:

By this extension you can run netstat command by a shell Linux but netstat only get who is connect to you device

With this new extension you can get all WiFi IP of a local net, is very slow, but works, doesn`t get MAC:
