Android Wear devices use bluetooth to connect to the internet, via your smartphone.
Does this mean the Smartwatch has its own IP on the local network?
Probably too late to reply but yes android wear devices do indeed have their own IP.
One way to find out is to debug over wifi under dev options. Once connected correctly, it should display its IP on the network with port 5555.
Alternatively, disable Bluetooth on the device, enable wifi and scan the network. Android wear favours Bluetooth connectivity so its important to disable it.

I have an Android device that has wifi and Bluetooth modules. I want to build applications to connect the device to the internet using a smartphone's data connection. Is this possible?
The smartphone will have wifi as well as data connection. Can the smartphone's data connection be shared through Bluetooth? Or is there better alternatives like wifi-direct or NFC? I am aware that enabling Hotspot on the smartphone is an option. But with hotspot, the issue of wifi being turned off makes it not usable for my use case. Is there any alternative to wifi-hotspot?
What will be the best option for this and what things should I consider when building my applications and services?
NFC is definitely not the answer, the data rate is far too slow and the connection unreliable and the OS does not allow it.
You might be better with a USB ethernet adapter if your phone support USB On The Go (OTG)
Your phone should already support sharing a data connection using Bluetooth. This is called Bluetooth tethering. But you also have wifi, so wifi tethering is also an option to share your data connection. No additional app is required.
Say I have a laptop (Windows 10) and an Android phone. The laptop does not have an internet connection and the Android does not have an internet connection.
I have an Xamarin app that uses a C# Web API that is deployed to the laptop (for testing). How can I connect the mobile to the laptop without any form of internet connection? I believe I have two options:
1) USB cable
2) Bluetooth
I believe I have to install a wireless hotspot on the laptop and then a reverse tethering on the Android.
Have I understood this correctly? Do I have to do this regardless of whether I use a USB cable or a Bluetooth connection.
Tethering is the name given to a mobile that acts as a hotspot. It make use of a network interface (Wifi, Bluetooth, USB port acting as Ethernet...) to share internet connection through the selected interface.
As you'll note I'm not incluiding mobile data in the list. Mobile data is used to connect to Internet. So your mobile is capable of connecting to internet via mobile data and share it via any other interface, i.e. Wifi, Bluetooth and USB (Ethernet)
At least in my mobile im able to just enable Tethering configuring it from Settings -> Wifi connections -> Share internet. Here I can switch on/off the desired interface: USB, bluetooth or Wifi. I can enable just one, both or even all of those
As far as I know a Xamarin app is an android app that embeddes a website and, optionaly but highly common, uses a server as an endpoint (your laptop in this case), also known as API.
So as you ask you don't want to have internet connectivity, all the connections must be made in a local network. To do so you could just enable tethering and turn off mobile data on your mobile. Then on your laptop, connect to your new network over wifi, enable ethernet or connect via bluetooth, depending on your choose.
Of course, you'll have to handle firewall on your laptop to ensure connections are made successfuly. But you should be able at last to ping each other.
I want to run a server(MQTT/HTTP) in my Andriod app over Hotspot. Nearby devices connect to mobile phone over phone's hotspot connection. Assumptions are that my phone has enough mobile data and hotspot support is enabled by the service provider.
Is it possible to connect devices over phone's hotspot?
Probably not. Most devices restrict all access between devices connected on the hotspot and the host. This is a security measure and can't be turned off.
I'm trying to throttle my device's network connection while testing it on Android studio. My strategy will be to try and reverse tether the phone to my macbook Air so the computer acts as a hotspot. The computer will be connected to the internet via wifi, and should be acting as an internet hotspot for any paired devices.
However the internet connectivity is never set, so the android device never connects online.
What I did:
Turn on network sharing via Wi-Fi, checked the Blue Tooth Pan Option.
Paired the devices (i.e. the phone is detected by the macbook and vice/versa.
Set up a static IP on the blue tooth pan configuration (see image).
And here is my Bluetooth setup on the device:
My phone is not rooted and frankly I'd rather not have to root it - but for some reason the phone is not detecting Bluetooth on the macbook air. But the macbook does detect the phone and is able to send files to it.
What gives?
I did working reverse tethering from MacBook Pro El Capitan to android mobile. Sharing the network Macbook Pro with Bluetooth PAN.
The trick is, to have android mobile rooted. First connect your mobile to any wifi, change advanced network options in mobile as Static IP, 192.168.2.1 router 192.168.2.1 DNS 8.8.8.8 8.8.4.4.
With terminal emulator apk, enter: su dhcpcd bt-pan
Now you can close your wifi in mobile.
be sure you have bluetooth pan configured as "Use DHCP with manual address" option matching same IP and DNS your put in android.
Note; of course android paired with the macbook, and sharing network and sharing bluetooth options active.
All working very stable.
Recently, I've tried to check transfer packages by proxy-ing from Mac to Android device. I think Bluetooth shouldn't be used for setting the shared internet but instead you should just share from your Ethernet to Wi-Fi.
(I tried to put in a comment as this is more like it since I don't have any images or a concrete explanation... but it wouldn't allow it).
Since I am newbie in Android, I don't know how to connect Android (2.1 on HTC Desire) with PPPoE using wifi connection.
So Please anybody know solution, then kindly help me.
If you want to use PPPOE client with android, you have to first root your android phone, otherwise, the application will not work.
The other method is to use your modem in PPPOE mode rather than bridge mode. In Bridge mode, you have to have a PPPOE dialer installed to your device to access the internet.
In PPPOE mode, the user id and password are punched in the modem itself, so you have to just provide the wifi (if enabled) password and you are connected to the internet. But there is a trick, some ISP's modem do not work, when switched to the PPPOE mode and have to be re-configured again.
yes you can...
there is a App called WiFipppoe...

As far as I know, PPPoE would be how you would authenticate to your service provider. Wifi just acts as a bridge between the router and the wireless device. The router is what should authenticate via PPPoE. Your device should connect to the Wireless Connection, that would put you on the same network as the router, the router authenticates to the service provider via PPPoE over the WAN.
Wifi is just a bridge between your device and the router. Now some routers have Wifi built in, but its like a Printer/Copier/Scanner, 3 devices jammed in to 1.
