Can I get any information about the device, whether it is smartphone or tablet with the help of their MAC address. Suppose, I am getting a MAC address (C8:20:F9:89:8E:2F). How can I trace, that it is a smartphone or tab ? Does they follow any specific pattern ?

I am running flutter_blue example,it doesn't raise any error but after searching for bluetooth devices it shows mac address instead of Local Names.alse after clicking on connect it doesn't connect.
I did make sure that other devices are ble support, even I purchased Bluetooth v4.0 usb dongle to be completely sure about Bluetooth version, but nothing changed.
also, I thought it may be related to my android phone,I reset(factory) the phone and wiped cache but nothing changed.
my cellphone is Sony Xperia Z3+ with android 7.1.1;
any Idea what is wrong and why I can't get devices name in scan?
It was gattserver, couldn't broadcast properly,I changed gattServer with another app in another smartphone and now it shows the Name of GattServer.
This question is not language-aware.
I wanna know how can I recognize a returning user on my website (Java, PHP, Coldfusion...) if he's using a dynamic IP.
Why? A lot of users of my web application use iPhone (with 3G networking) for accessing. IP changes each time, so I always see them as "new" users.
I know it's unlikely to track MAC address in web pages but.... what solutions are there for such a common problem?
Maybe a suitable iPhone app? ;-)
It's not quite possible to find original requesting machine's MAC address. You should use Cookies to track users.
You can find more info about MAC Addresses here.
A Media Access Control address (MAC address) is a unique identifier
assigned to network interfaces for communications on the physical
network segment. MAC addresses are used for numerous network
technologies and most IEEE 802 network technologies, including
Ethernet. Logically, MAC addresses are used in the Media Access
Control protocol sub-layer of the OSI reference model.
Why not do what everybody else does and use cookies?
As other said, you could easier get what you want with cookies...
and, reading your question and purpose, i'm not really sure that if a user uses it's iPhone via wifi and browse to your website and than it come back again via 3G the MAC address doesn't change... i thought that MAC address is unique not for a device, but for a single hardware component in it: this mean that an iPhone could have a MAC for wifi hardware and a MAC for 3g hardware... if it works as on my powerMac... i can see my computer has a mac address for my ethernet and one other for my wifi...
but i'm not an hardware expert, so (all readers), please consider this answer as a question too, and if there is any net expert on line...
Does anybody suggest a mobile printer able to print receipt with a good SDK to interface wireless an iOS application adhoc developed ? The printer should be small and should use rechargeable batteries for field use.
I cannot use wifi because not always a trusted access point (customer premises) is available, so I think to use Bluetooth, but of course any suggestion is welcome !
FYI I already checked Zebra printers SDK for iOS but it seems able to print only using a TCP/IP address, it means (for as I know) I should use wifi. In my case the application should be used in the field from an iPad connected with cellular network. In iPad there is no hot-spot and not always there is an available wifi access point tho connect the iPad and the printer the the same network to use TCP/IP addresses. That is the reason I'm guessing the last chance should be bluetooth.
Unfortunately iOS5 does not support Bluetooth printing.

Have you considered VPN via WEP to a network printer?
Alternatively some printers can be set up with their own email address. PDF attachments can be sent via this address to be printed. These emails can be sent encrypted.
I know that this isn't the IDEAL answer, but it is likely to work for the time being until iOS is properly updated.
Yes, I have Bluetooth printer for IOS device, it is Apple MFI approved
see details from this URL http://www.bluebamboo.com/other_file/P25i%20Datasheet%20%28EN%29%20v1.0%2009-Oct-2011.pdf
I know you already accepted an answer, but here's another one: have the technician bring their own wireless base station (AirPort Express perhaps) and create his own wireless network (that won't have internet access, but that's not needed) with appropriate security. Then you can use any HP wireless capable printer and have the iOS device and the printer connect to the wifi network created by the wireless access point (which should be set with DHCP to vend IP addresses in a non-routable range like 192.168.x.x, obviously).
We also have a Bluetooth printer that is MFI certified along with an easy to understand iOS SDK. Please take a look at the EZPay App on the Appstore. The app's currently in Japanese (fir one of our clients) but the description explain a little about the printer. I'm currently traveling at the moment, but if you shoot me an email from the contact info on the App Store. I can get a few other things out to you. Cheers... B
No need to develop a full blown SDK, check out Mobi Print. it has the Zebra sdk already implemented and connects to any webservice or ODBC database. It also has stored label/receipt formats in there app so just upload your format and should be good to go.
here is link for Mobi Print
Can I determine if a device is IPhone/IPad/IPod or Android from its MAC address ? MAC addresses can be used to identify the manufacturer but can I distinguish a Macbook pro from an IPhone ?
Unless Apple uses unique wifi chipset suppliers for a Macbook that would never be used for an iphone (e.g. samsung for iphone and toshiba for macbook), a mac address will only ever tell you who manufactured the particular wifi chip in use. Maybe certain ranges of mac addresses would only ever show up in one type of device, but you'd have to compile that list yourself.
Without using the private APIs, is it possible to programatically determine the MAC address of the access point that the iPhone is connected to?
I understand that this should be doable using the core BSD libraries, but we are new to this, so it would be great if someone can point us to some starter code.
Note: we're trying to determine the MAC address of the remote device - not the MAC address of the iPhone.
I believe that the NSHost class exists on the iPhone. If you create an NSHost instance for the machine you're connected to, then sending it an -addresses message should give you its IPV4 address and its MAC address, if I recall.
