Im currently working on developing an app for Windows Phone 8 and one requierment is to display the phones local Bluetooth address/device id.
Is this possible?
If so does anyone know how?
you can try this first off all enable the capapbility device identity and then write this
byte[] myDeviceID = (byte[])Microsoft.Phone.Info.DeviceExtendedProperties.GetValue("DeviceUniqueId");
string DeviceIDAsString = Convert.ToBase64String(myDeviceID);
this might help you......
after finding all peers, you open socket to a peer then you have:
peerSocket.Information.LocalAddress

I'm trying to connect a bluetooth device (ESP32, peripheral) with Web Bluetooth (central). I send an addvertising packet and I can see the device on the web page, but I fail to connect to it. My code for the ESP32 looks like this: (MicroPython)
ble.gap_advertise(interval_us=100, adv_data=bytearray(b'\x02\x01\x06\x06\x08\x45\x53\x50\x33\x32\x11\x07\x26\x6c\x34\x7f\xb2\x38\x61\x82\xbe\x4d\x1d\x64\xf1\xf7\x93\x16\x02\x19\x80'),resp_data=None, connectable=True)
In Web Bluetooth (JavaScript) I just request a device and try to connect to the gatt.
Can anyone help me out?
Thanks in advance!
The JavaScript does work with another bluetooth peripheral. (RN4678)
And in JavaScript I can find the peripheral (ESP32) after filtering, but I can't connect to it.
JavaScirpt:
server = await device.gatt.connect()
The code stops at that point.
MicroPython:
The GATT is defined using:
ble.gatts.register.services()
I'm trying to use my own service, not a SIG defined one. So I advertise b'(x...') which contains the flags, the service and the device name. And it works with the nRF Connect App. I can send and recive data. But it doesn't work with the bluetooth enabled web browser.
Thanks for your help!

This is the board that I'm using Arduino Uno with inbuilt wifi. I'm unable to connect it to my wifi network
I tried doing what is mentioned in the link
https://www.trojanc.co.za/2017/11/05/arduino-uno-wifi-network-setup/
But the webpage won't open
Then I also tried uploading the code mentioned in below link to ESP8266 by pushing on 5th ,6th,and 7th dip switch
https://arduino-esp8266.readthedocs.io/en/latest/esp8266wifi/readme.html
But it still does not connect to the internet
On the terminal it shows
Hard resetting via rts pin
Nothing is visible on serial monitor or arduino IDE
Thanks in advance
There are some switch to control connection between USB, Atmega and ESP8266/Wifi
pin 1 and 2 on : Atmega connect to ESP8266 there is not connection to USB/Computer
pin 3 and 4 on : USB/Computer connect to Atmega, so you can upload a skecth
pin 5 and 6 on : USB/Computer connect to ESP8266/Wifi
make sure you have been setup this switch correctly depend on your need.
I wonder how smartphones get the right APN Settings. Even when i am in a other country.
For example:
It is not possible to dial in in a Netherlands APN when i am in Austria. But everytime my smartphone finds local APN´s it is able to connect to them.
But how if it dont know the right APN settings?
I have a Modem which is connected to a Raspberry Pi and i have tried to put several sim cards from different countries in it which i want to use when i am not in Austria. For every single connection i must give the Dial Program (wvdial) the right APN settings to make it connect.
Isn´t it possible to search for APN´s in reach and automatically connect to them?

There is something called config-sms witch is a hidden sms the provider sends to your smartphone.
What hardware/software do I need to setup a machine that monitors incoming text ("SMS") messages on a phone connection? The software needs to be able to read the message, copy it to a database and then delete it.
Three ideas:
Use google voice instead of a cell phone, and your received SMS will arrive as email
Obtain a cheap phone that features a serial port on the headset connection and can use AT commands (AT+CMGR or something like that) to receive SMS, connect this to a computer's serial port using a cable with level translation
Use an Android phone and write an application which does this.
Is it possible to have a j2me app on a mobile to act as a "SMS gateway" that will handle incommming messages, do a query on a database via GPRS and reply the user back?
This is entirely possible on any J2ME handset that supports JSR 120 (i.e.: most of them). However as Wonil said, you can't just process ANY incoming SMS message. It has to be an SMS sent to a port number on which your app is listening (using a server connection as Wonil explained).
It wouldn't be automatic unless the app was signed (as confirmation is generally required for sending SMS and network access).
Another approach is to tether your phone to a PC using a USB cable/bluetooth/IR, open a serial connection using the phone as a modem, and write a program to listen for new SMSs using AT+CGML as described here. This would allow ANY incoming SMS to be processed (no port number required), and without any annoying confirmation prompts.

I think you should check about JSR-120 documentation to confirm.
But, in my thought it might be impossible. If you want to receive message by using JSR-120, you should assign specific end point(port number) to listen as like below:
serverConn = (MessageConnection)Connector.open("sms://:5000");
So, you can't catch all SMS messages. It can't be a gateway then.
It probably depends if your phone supports it. Have a look at the J2ME Wireless Messaging API:
The Wireless Messaging API (WMA) is an optional package for the Java 2
Platform, Mobile Edition (J2ME) that
provides platform-independent access
to wireless communication resources
like Short Message Service (SMS).

This article has some examples which can probably serve as a starting point for what you want to achieve: http://www.ibm.com/developerworks/wireless/library/wi-extendj2me/
Edit: as others have pointed out, you might not be able to receive all messages.
