CANT receive data via a network, help me please

Hi, I am not as newbie as I look like to.
I am trying to receive data through a network. The problem is that I dont know the file size, so I kept reading until reaching the end of file and the save it to a file. The problema is that I am never geting the -1 result from the read method.
Now, I noticed that the -1 is returned when I close the DataOutputStream. So thats okay. The problem is that the sender is not make in java, but on pocketBuilder. And I cant ask for the client to close an outputStream. So Is there any way to just read the data without knowing the number of the bytes to receive and doesnt waiting for the end of the stream.

When the number of bytes read is less than the array
lengthThat doesn't necessarily mean you're at the end of the data.
Any other wahy, maybe a timer (if is not receiving
any byte for 20 seconds then cut the conexion?)Again that doesn't necessarily mean you're at the end of the data.
There is no way to know you're at the end of the data without either an application protocol containing the length, or a socket close at the sender.

Receiving data via 802.15.4 radio

Hi,
I am familiar with using a bluetooth radio to receive data wirelessly through the serial port using VISA in LabVIEW. However due to the range limitations of my bluetooth radio, I'd like to have a go at receiving date via from an 802.15.4 radio. Has anyone any experience doing something like this and is it possible using VISA and a serial port? Presuming I know the data packet format, it should be ok right..?

Hi Strokes,
Do you plan on buying a third party 802.15.4 wireless device that connects to your computer through the serial port? What hardware do you intend to use?
I assume you wish to use your existing code that was designed for the Bluetooth dongle. Are you communicating using a serial protocol or Bluetooth protocol (Bluetooth or Serial VIs)?
What is your current setup? Do you have a Bluetooth device that connects to your PC via serial? What hardware do you have sending and receiving the data?
Have you seen the NI Wireless Sensor Networks and have you thought about Using LabVIEW with TCP/IP and UDP?
Kind Regards
No I plan on using a Shimmer device (see here) which as a 802.15.4 radio on it's circuit board to communicate to a laptop via serial port.
I'm not set on using the existing code as used with the bluetooth radio on the Shimmer, but if it will reduce the workload then yes of course I will. The existing code currently uses serial protocol so I guess I could modify the existing code?
My current setup is: I have a Shimmer (wireless sensor, accelerometer in this case) that has both a bluetooth radio and 802.15.4 radio. Due to my application needs, I would like to transmit data to the serial port via the 802.15.4. There is existing code which allows the Shimmer to communicate with the serial port using Bluetooth radio.
I'm not looking for code or anything, just wanted to know how to go about it and if I could use VISA which I'm fairly familiar with.

Iphone 4 only receiving sms from certain networks- help?!!!!

Iphone 4 is only receiving sms from certain networks - help?!!!

Have you contacted your carrier to report the problem? This is not (and can not be) a problem with the phone. It's a problem with your carrier and/or the way they have your service provisioned.

My motor receives data via a serial connection, but it won't move. What am I doing wrong?

Hello everyone,
as the title says, I am trying to use a motor called "MP285" by Sutter Instruments via LabView. The control unit of this motor only has a RS232-output, but I use a Serial-to-Usb-Adapter to connect the device to the PC.
My problem is the following:
I tried to perform a basic Input/Output test by using the Ni MAX an sending ASCII strings to the control unit (after configuring it according to the reference manual), which worked fine. I also used the "jabber"-function of the control unit to send an output string to the PC and was also able to read that string from the buffer. Besides, when I used a LabView-VI to send a command via VISA Write, it also appears on the display of the control (at least the ASCII letters).
Accordingly, I assume that the Serial-to-USB-adapter does work. Is that for sure, or can the adapter evoke any other problems?
However, when I try to use the shipped controlling software, the motor won't work. Furthermore, I contacted the customer support and they sent me some VIs and a LabView-Project, which was tested by the company. Unfortunately, it did not work for me. The motor wouldn't move, when I sent the command, although the LabView-interface indicates that there the connection between PC and controller has been established. As the program has many features and I only need a command to move the motor, read the position and set the origin, I tried to build my own VI. I had a look at some basic VIs for motor control and referred to the manual.
As it seems, the controller uses data streams of full bytes (8 bits, not ASCII) in Big Endian for its strings (I copied the information at the bottom of this text). Thus, I tried to concatenate particular strings to send it via VISA in the correct form (see attached). Do I have to convert the "m" into hexadecimal explcitly? I looked up "Convert ASCII to Hexadecimal", but when I try this, the output string does not change.
However, when I send this string to the controller in normal mode, nothing happens . When I activate the Input/Ouput test (see above), there is a m displayed on the controller unit. So I guess, I am messing up the command structure. Can anybody help me please?
Kind regards
PS: Sorry for cleaning up the diagramm..
PPS: For some reason, I could not attach the VI because " The contents of the attachment doesn't match its file type". So, I changed the name in "-vi" instead of ".vi" as suggested by a forum user. Hope this works for you!
Excerpt form the reference manual:
General Information:
"Command requests are single bytes followed by optional parameters and terminated by a
carriage return (CR, 0Dh). The data stream consists of full bytes (all 8 bits — not ASCII.
The lowest order byte (for example, of the four bytes encoding the X coordinate) is the first
into the controller and is the first out. The default Baud rate is 9600. Commands are
processed bytewise by interrupt and executed only after the terminating CR is received.
There are no delimiters within command strings. The controller will reply with carriage
return (CR, 0Dh) at the completion of normal command processing."
Command structure:
Get Current Position      command ‘c’CR 063h + 0Dh
                                           returns xxxxyyyyzzzzCR three signed long (32-bit) integers + 0Dh
Go To Position                 command ‘m’xxxxyyyyzzzzCR 06Dh + three signed long (32-bit) integers + 0Dh
                                            returns CR 0Dh
Setting up for Serial Communication:
First, use the 9-pin serial port cable provided with the MP-285 to connect the “serial port” of
your computer to that of the MP-285 controller. Next configure your terminal emulator (e.g.,
HyperTerminal in Microsoft Windows (9X and above) to the following settings (or their
equivalent):
• TTY mode
• Echo typed characters locally only (do not echo input to the computer serial port back to
the controller)
• Baud rate to 9600
• 8 data bits, no parity, 1 stop bit
• COM port - set to the port to which you have connected the MP-285 controller
Solved!
Go to Solution.

Thank you for your feedback!
To make this clear: I dont know if the motor MOVES when sending the appropriate command via MAX. That is because I dont know how to enter the binary? command. I only tried to send some string like "dear moto please move" to see if this ASCII string can be displayed on the control unit while running the input-mode (which I described above).
This works for both, MAX and my Labview-Vi.
However, these are the I/O traces:
1. MAX: I sent the string: "Test"
NI I/O trace:

Not able to receive data via bluetooth: curve 8520

hi guys..i have bb curve 8520. i m nt able to receive data from other mobiles or pc via bluetooth. the mobiles & system can be paired with my BB but i cannt receive data from others. also it gives error message FILE TRANSFER SERVICE NOT AVAILABLE

Hi and Welcome to the Community!
See this KB:
KB05409 Transfer a file using Bluetooth technology between two BlackBerry smartphones
If your other device is non-BB, then substitute, in the KB, the appropriate instructions for your other device. Unless you are on BB OS 6 or 7, do not skip the "Receive Using BlueTooth" step on the receiving BB...nothing will transfer if you do.
Good luck and let us know!

HT1212 hi...i brought an (American Sprint) i phone 4s from ebay, Now i cant active the phone. can you help me please

Hi there, I bought an iPhone 4s (sprint USA) from eBay. Now i cant active the phone here in UK. How can I active this phone ? Can anyone help me please.

Why on earth did you purchase an American iPhone if you knew you were going to activate and use it in the UK?
If you like in the UK and you want to use the phone in the UK, then buy an iPhone 5 that you can actually use in the UK.
So you need to purchase the phone either through one of the phone companies of your choosing by taking out a contract - so EE (Organge and T-Mobile 4G), Vodafone, 3, or o2 or buy an unlocked iPhone directly from the Apple store itself for full price.
If you buy from e-bay you have no valid warranty if the phone goes wrong, so you won't be able to get the phone fixed in the UK, but you will physically have to go back to the US to get it fixed - iPhone warranty is country specific and NOT worldwide. If you buy the phone in the UK, then you will have an EU warranty.
Return the phone to your seller at e-bay for a full refund and start again and buy and iPhone 5 that is unlocked from the UK and then you will be able to activate it.
Do you have a sim card because you need a sim card to be able to activate a phone and have you connected it to iTunes?
Unfortunately, not all US models of the iPhone 5 have sim card slots or if they do, they are not all unlocked, so if this is the case with your phone, then you won't be able to activate it here in the UK and there is nothing that you can do. You will either have an unusable brick or you will have to return you phone to your ebay seller for a full refund.

IPhone 4S - Could not scan for wireless networks - help needed please

Hi
Can anyone offer any advice please.
My 4s has developed an wifi issue. It cant scan for wireless networks My bluetooth is intermittent also.
I have turned it on/off, rebooted, reset all networks, reset to factory settings, set to airplane mode, set to do not disturb - everything and all to no avail.
I am under a two year contract with Vodafone and went into their branch at Merry Hill, Dudley today and they failed to help me saying it was nothing to do with them.
I am at a loss as to what to do. I have not had any accident with my phone and it is still in mint condition.
Can anyone please offer any suggestions on what to do.
Many thanks.

Apple's out-of-warranty policy is a feeble attempt at covering up it's issues and is a clear cut demonstration for their lack of respect for its user base. Their WIFI/Bluetooth dropping issues have been around for several years now and it started within the last 3 IOS updates. Apple engineers acknowledge this problem and don't have a solution yet... this was confirmed at the Genius Bar at their Nashua, NH outlet. My phone is 6 months passed warranty and my Verizon contract isn't up for renewal for another 6 months.
There are a lot of complaints about this (a LOT), yet Apple continues to stick its head in the sand instead of owning up to providing shoddy hardware and/or glitches software. They certainly don't want to be in the business of replacing phones, so they put the onus on us by charging $200 for a replacement... such a deal for Apple!
Apple's support communities are basically useless on this subject with a lot of screwy so-called solutions to work around their flaws. I've seen one fix where you heat up the phone with a hairdryer until the temp warning appears and then refrigerate it for 10 minutes... then BINGO, it's all fixed! Ya right!!!
Resetting network settings, or all settings (including a complete reset) is ineffective and appears to do nothing more than to further upset Apple users once they realize that they have wasted their time following Apple's so-called fix.
I just wonder if or when Apple pulls it's collective head out of the sand will they be able to see that their competition has surpassed them by leaps and bounds. There really isn't any good reason to stick with Apple now-a-days since their conscience passed away. Their competition offers superior technology while Apple continues to impress up with new connector technology and placement of their sockets.
I am finished with Apple and am incredibly sick of their spoon feeding what they want rather than what we want.
The best way to make Apple improve is to provide them with a taste of their own WIFI/Bluetooth offerings by DROPPING THEM!
They have abandoned us and have no problem trying to charge us to replace their flawed technology instead of doing the right thing!

Cant receive or send picture messages

Hi can someone please help me, I have recently bought the Nokia C3 and I cant receive or send picture messages, can someone please advise. Thanks

You need to contact ur operator and ask them to send u MMS & wap and internet settings (Or only MMS), u'll most probably get them via configuration sms, open it, go to options and select "save" phone will ask if to set it as default, select yes. that's it. Try to send Picture message.

Once per day client exec sql query which take 15Meg of data from database.
It's take a lot of time, much more if I transfer this data through FTP.
Why it's happend?
May be server can compress data before transfer?
Help me please.

Receive data from PayPal

Hello.
Assuming that I send data into PayPal (with the use of "HTML Variables for PayPal Payments Standard"):
var variables:URLVariables = new URLVariables();
variables.cmd = "_xclick";
variables.business = "A8AJGG5PS2GKE";
variables.upload = "1";
variables.item_name = "some item";
variables.amount = "123";
variables.currency_code = "USD";
variables.lc = "pl";
variables.page_style = "PayPal";
variables.return = "my site";
variables.re = 2;
variables.no_note = 1;
variables.no_shipping = 1;
variables.notify_url = "[email protected]";
var request:URLRequest = new URLRequest("https://www.paypal.com/cgi-bin/webscr");
request.method = URLRequestMethod.POST;
request.data = variables;
navigateToURL(request, "_blank");
Does anyone managed to integrate PayPal IPN - "Instant Payment Notification"-
(https://www.paypal.com/ipn/) with AS3 in order to receive data from PayPal?
Could you please show any example of using it.

My idea is as follow:
1. .swf on you page sends variables into PayPal
2. After finishing the payment on PayPal, the customer is auto-redirected to your page ("return" variable)
3. Customer returns to your page. PayPal does NOT send any payment data there.
Separately in the background, you receive a form POST from PayPal at a different URL (notify_url variable) - (here resides the php that I added below).
4. You post back a form with cmd=_notify-validate and all fields you received from PayPal. PayPal responds with a single word VERIFIED or INVALID
5. If you receive VERIFIED, you can process payment
This method means that you can easily update for example your MySQL database but unfortunately you have to reload .swf file each time - and that's why it is not a perfect solution in my opinion;
PS:
- variables.return and variables.notify_url must be absolute urls
- notify_url must also allow anonymous access from outside of your network
- firewall must be opened to host: notify.paypal.com
- in your business PayPal account:
Auto Return = Enabled in account profile
PDT = Disabled in account profile
IPN = Enabled in account profile
- php file:
<?php
// read the post from PayPal system and add 'cmd'
$req = 'cmd=' . urlencode('_notify-validate');
foreach ($_POST as $key => $value) {
        $value = urlencode(stripslashes($value));
        $req .= "&$key=$value";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: www.paypal.com'));
$res = curl_exec($ch);
curl_close($ch);
// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
if (strcmp ($res, "VERIFIED") == 0) {
        // process payment
else if (strcmp ($res, "INVALID") == 0) {
        // log for manual investigation
?>

How to stop apps from sending and receiving data?

Or does it even matter because I have cellular data turned off...

If you have cellular data turned off apps can still send and receive data via WiFi. But why do you have apps that send and receive data if you don't want them to send and receive data?
