mac-address

问题 I'm looking into suggestions on how to convert a 64-bit die revision field into a 32-bit MAC address I can use a for a wireless application to avoid collisions. The die information is struct { uint32_t lot; uint16_t X_coordinate; uint16_t Y_coordinate; } I don't know the range of coordinates, but based on a few samples, I think the coordinates are limited to < 256. That effectly reduces the space by 2 bytes. But the lot number is fully populated. I'm going to try this (pseudocode to make it

问题 I want to get the bluetooth MAC address in iOS 3.2 and later, but can't find any usable way, could someone give me some advices? 回答1: It's not exposed publicly, not even at the level of BSD sockets.

问题 I am developing a VB.net windows forms application. My application connects to a name specified computer on network and gets its MAC address and performs a check, in order to prevent the use of the application "out-of-office". The Mainpage load event is as follows: Private Declare Function inet_addr Lib "wsock32.dll" (ByVal s As String) As Integer Private Declare Function SendARP Lib "iphlpapi.dll" (ByVal DestIP As Integer, ByVal SrcIP As Integer, ByRef pMACAddr As Integer, ByRef PhyAddrLen

问题 I have a situation where I ping a range of IPs in the network. Then, I try to connect to the successful pings. My aim is to connect to specific equipment that has a specific MAC prefix. For example, when I ping a range of 100 IPs, I might get 20 replies. These replies include computers, printers, and possibly the hardware I am trying to connect. Currently what happens is that when I try to connect to anything other than the hardware I would like (i.e computer, printer) I get a timeout

问题 I'm trying to get the MAC address of a linux system with this code: try { ip = InetAddress.getLocalHost(); NetworkInterface network = NetworkInterface.getByInetAddress(ip); byte[] mac = network.getHardwareAddress(); // System.out.print("Current MAC address: "); for (int i = 0; i < mac.length; i++) { is = is + Integer.parseInt( String.format("%02X%s", mac[i], (i < mac.length - 1) ? "" : ""),16); } } catch (UnknownHostException e) { e.printStackTrace(); } catch (SocketException e) { e

问题 I am working on the iBeacon technology and I can't find any answer to a particular point concerning the address type. I found the documenation (bluetooth specification) explaining what are the address types but I can't seem to find how to chose between the two types (public and random). Here is an example where I found it (it is a sniffed packet transmitted by an iBeacon on a Raspberry PI) : http://i.stack.imgur.com/QF5gf.png and http://i.stack.imgur.com/NHY6x.png (sorry I can't post images

问题 I have been reading a number of posts here on stackoverflow about android not having unique identifiers. But could I not use the MAC address of the device as a unique id? If not, why not? If yes, does anyone know how to get it programmatically (i.e. a piece of code [please])? FYI: My app requires network so devices without networks won't be able to install it. 回答1: But could I not use the MAC address of the device as a unique id? Not 100% reliably. If not, why not? Here is what Google has to
