We have device ""FT245R USB FIFO" USB to Seriel for communication from Windows 10 using D2xx driver.
FT_OpenEx() API works without any issue. But whenever user unplug/plug new USB device(Mass storage device) , during that time FT_OpenEx() API failed to execute, so handle invalid and our data communication interepted. Could you let us know what can I do further to resolve this issue ?
Note: I have opened handle using following command FT_OpenEx("FT245R USB FIFO", FT_OPEN_BY_DESCRIPTION, &handle), I open it everytime, whenever I need to talk with communication device. tried with seriel number of the device , but still communication fails when unplug/plug other USB device.

I want to create a pppoe network interface in the networkset with SCNetworkConfiguration API, but I did many times for it just create modem interface.
Anyone get the same problem or have a solution about it? Thanks
Happy new year.
It's just easy, I try n times debug it and find the answer.
I'll put it on github

Hey I'm new to Arduino programming, I was wondering how i can connect my device to store data to parse.com.
I know the REST API Key but not sure one what to do. Any help would be appreciated, and if possible can you provide source code or examples.
Thanks!
This is now possible. An Arduino Uno + ethernet shied still can't make HTTP requests, and parse.com still needs HTTPs, but Temboo makes it possible. Here's what you need to do:
Create an account at Temboo.com
Go to the Parse bundle
Find the Choreo you're interested in e.g., UploadFile, and test it out from the Temboo website
Turn on IoT Mode, set up your shield, and use the generated Arduino sketch code to connect your board to Parse.
Here's a blog post about Temboo's Iot Mode - the feature makes all of this possible:

I hope this helps.
I'm trying to connect a Glucose and Heartrate monitor LE devices using Windows 8. It is being detected just fine and default LE is used for the device. I'm trying to use the sample BLE http://code.msdn.microsoft.com/windowsapps/Bluetooth-LE-Metro-sample-a2ba1b5b but getting 80070057 error.
I have read some post that a custom driver is required. I run it using the sample in Mac and it works just fine. The sample application was able to use the device without any issues. Is there a way to access and use the device without creating a custom driver?
Thanks!
The sample is just a facade to the user. Driver is always needed in order to communicate with hardware. For some standard devices the OS might include a default driver (e.g., standard Web cam) with a predefined set of functionality but for all the rest a vendor-supplied driver is required.
I want to connect my mobile internet to pc using bluetooth device. I installed blue soleil software in my pc.
Steps:
I can able to pair my cellphone with pc bluetooth device.
I selected my device and select bluetooth dialup networking service.
It asks an alert "DUN connection with device?" in my mobile.
After Clicked "YES", connect bluetooth DUN connection window opens.
In that window there was a fields "User Name", "PassWord" which i leave empty and then in "Dial = *99***1#" and click Dial button.
After that it say "Registering your computer on the netwok.." and become fails.
The Error is as "error 734 the ppp link control protocal was terminated"
The same procedure should be followed for Nokia 3110c it works fine.But in my samsung mobile c3053 it not connected also i am tryig with samsung corby pro BT3510 mobile .
Is there any settings changes needed for samsung mobiles ?
When I've seen this error in the past, it generally indicates that the username and password for the connection is not correct. (Many GPRS configurations do not require a username and password, but some do.)
Or, the GPRS APN is not configured correctly.
If you are trying to use the device as a general purpose modem, it can be difficult to set the GPRS APN without extra dialer software. The easiest way is to add an "AT+CGDCONT" command to the "extra initialisation commands" that can be configured for the modem in the Windows control panel.
A specific example of what would be configured for this "extra initialisation command" is:
AT+CGDCONT=1,"IP","internet"
You would replace internet in this example with the name of the GPRS APN to which you want to connect.
Also, you can refer the following link for checking the connection:

I almost got mad as a result of this problem few days back. I tried all the solutions suggested in different forums but to no avail.
My issue was not of insufficient airtime as suggested by some folks, nor the ppp link settings but because i had a space before the username input in my username and password field input in my dial up box.
So folks, if you are getting a PPP link termination error, check user name and password fields carefully for a single SPACE in this field will automatically call up this error when you dial. eg
My user name is: 7032564825#bluebroadband.com
Password: 1234
A space before the first number (that is 7 as in the example above) will trigger this error message. So guys give it a check before you search for other options like airtime and dial up settings.
If you get "734 the ppp link control protocal was terminated" with a SAMSUNG mobile phone, the problem is in the phone. On Phone Settings -> PC Connections select that your phone will always be in "PC Studio" mode. If you select other modes or "Ask each time" you will get 743 when trying to use the phone as a modem.
the solution is very simple. you just need to put extra initialization command.
Please don't read too much tech about ppp and its meaning.
i had same problem in 2006 what you have to do is in modem( the active e.g. bluetooth DUN modem or hardware modem or mobile as a modem) just go to propertise of : my computer>device manager> modem
then modem propertises> advance> Extra Initialization command
here you just have to put command
e.g i use bsnl net so command will be:
at+cgdcont=1,"ip","bsnlnet"
bsnlnet is APN, if you use airtel, anp is "airtelgprs.com"
I too faced the same problem, I even searched on line for a solution, but I figured my self based on the instructions that were given from the customer service centre. I have been using a bsnl network, to avoid ppp link control termination problem
Activate GPRS by sending START sms to BSNL service initiated number
Wait for some time at-least 2 hours to get activated after activation you will receive a activation message.
Since bsnl network, we have to create a APN - Access Point Network
i) create an APN as - bsnlnet
ii) password as 1111
Now change your access point network as bsnlnet switch on your mobile data.
Enjoy Internet.....
