  • Developing a GPS car tracking system

    - by Click Ok
    I'm in the brainstorming phase to develop a GPS car tracking system requested by a customer. I myself know the directions to build some GPS system to mobile phones and etc. But sincerely I don't know how to start in that project. That is the scenario: 1) The cars will get a device with a SIM CARD that will emit GPS signals. 2) My customer will in any place (home, work, etc) with a web connection will see in the map where the car is located. For me, I have not problems at get the GPS data, convert to usable info and show the position in some map system (like Google Maps or MS Bing Maps, by example). My problem is, how I do to retrieve that "GPS Signal" from device in the car? I will need some kind of "Receiver Device" connected to a web server machine in order to my application to consume that data? Or "automagically" my sodtware will receive the info from a third-party web-service? Or what?

  • dial windows serial modem from php

    - by bumperbox
    I am trying to dial a phone number from php (i have a client list in a database, and thought i could use it to ring them when i click on their name here is my code, it doesn't seem to work. I can hear the phone line click, but it doesn't seem to dial. maybe i am missing some command that needs to be sent prior to atdt? $device = "COM4"; exec("mode $device BAUD=9600 PARITY=n DATA=8 STOP=1 xon=off octs=off rts=on"); $comport = fopen($device, "r+b"); if ($comport === false) { die ("Failed opening com port"); } else { echo "Com Port Open"; } stream_set_blocking($comport, 0); $atcmd = "ATDT222222222222\r"; // dial fake number if (fwrite($comport, $atcmd ) === false) { die ("Failed writing to com port"); } else { echo "Wrote $atcmd to com port"; } fclose($comport);

  • weird characters displayed during serial communication OSX

    - by nemo
    I have tried communicating via serial (OSX w/ prolific drivers - USB RS232 adapter - Tx,Rx and GND pins on device serial ttl port) to a device and done so successfully using screen /dev/tty.usbserial 115200 8N1 I get to log in and use it as if I was SSH or TelNetted in... However whenever I try to go into system recovery mode (holding CTRL+1) while the device is powering on, it starts displaying weird characters and until I close the screen session it will continue showing weird characters: Of course when we tried doing the same thing on my boss' macbook running windows and PuTTY and everything worked fine, even in system recovery mode; characters were displayed properly. What gives? Id like to learn the intuition to use because up till now I concluded that since I can bot into the system and see characters normally everything about the connection should be fine and its must have been the recovery partition that was broken. This was wrong of course... Niko

  • What one-time-password devices are compatible with mod_authn_otp?

    - by netvope
    mod_authn_otp is an Apache web server module for two-factor authentication using one-time passwords (OTP) generated via the HOTP/OATH algorithm defined in RFC 4226. The developer's has listed only one compatible device (the Authenex's A-Key 3600) on their website. If a device is fully compliant with the standard, and it allows you to recover the token ID, it should work. However, without testing, it's hard to tell whether a device is fully compliant. Have you ever tried other devices (software or hardware) with mod_authn_otp (or other open source server-side OTP program)? If yes, please share your experience :)

  • iPhone tilt direction

    - by Tate Allen
    Hi all, I am making a simple, tilt controlled game using UIKit. So far, when I tilt the device the character moves in the appropriate direction. What I want him to do is to change the direction he is facing when I tilt the device. For example, when I tilt it left, I want the character to face left. Is there a way to detect whether the device was tilted left or right? If so, could you point me in the right direction please. Thanks, Tate

  • CoreLocation on iPod Touch, location caching and other conundrums...

    - by Moshe
    I have a few questions about Core Location. 1) Should the user refuse permission for my app to use core location, or core location is unavailable for some reason, is there a fallback? (Device Locale, for example?) 2)Can I cache a device's location for next time? Does Core Location do this itself? 3)I really need the sunset time in the user's area during the mid-spring season and I have a function to do that, once I have the Latitude and Longitude of the device. Perhaps I can just make an assumption about the time based on Locale? (Example: In the US, assume approximately 7:00pm.)

  • implementing ioctl() commands in FreeBSD

    - by thecoffman
    I am adding some code to an existing FreeBSD device driver and I am trying to pass a char* from user space to the driver. I've implemented a custom ioctl() command using the _IOW macro like so: #define TIBLOOMFILTER _IOW(0,253,char*) My call looks something like this: int file_desc = open("/dev/ti0", O_RDWR); ioctl(file_desc, TIBLOOMFILTER, (*filter).getBitArray()); close(file_desc); When I call ioctl() I get: Inappropriate ioctl for device as an error message. Any guess as to what may be doing wrong? I've defined the same macro in my device driver, and added it to the case statement.

  • Serial port determinism

    - by Matt Green
    This seems like a simple question, but it is difficult to search for. I need to interface with a device over the serial port. In the event my program (or another) does not finish writing a command to the device, how do I ensure the next run of the program can successfully send a command? Example: The foo program runs and begins writing "A_VERY_LONG_COMMAND" The user terminates the program, but the program has only written, "A_VERY" The user runs the program again, and the command is resent. Except, the device sees "A_VERYA_VERY_LONG_COMMAND," which isn't what we want. Is there any way to make this more deterministic? Serial port programming feels very out-of-control due to issues like this.

  • GNU ld removes section

    - by Jonatan
    I'm writing a boot script for an ARM-Cortex M3 based device. If I compile the assembler boot script and the C application code and then combine the object files and transfer them to my device everything works. However, if I use ar to create an archive (libboot.a) and combine that archive with the C application there is a problem: I've put the boot code in a section: .section .boot, "ax" .global _start _start: .word 0x10000800 /* Initial stack pointer (FIXME!) */ .word start .word nmi_handler .word hard_fault_handler ... etc ... I've found that ld strips this from the final binary (the section "boot" is not available). This is quite natural as there is no dependency on it that ld knows about, but it causes the device to not boot correctly. So my question is: what is the best way to force this code to be included?

  • Different NSTimeZone names being returned

    - by Michael Waterfall
    I've noticed that on some devices the NSTimeZone's name method for a particular timezone can return different values. When testing the Brisbane time zone, my device returns @"Australia/Brisbane" whereas another user's device returns "Etc/GMT-10". Both iPhone's are running 3.1.2. The Date and Time Programming Guide for Cocoa states that: timeZoneWithName: The name passed to this method may be in any of the formats understood by the system, for example EST, Etc/GMT-2, America/Argentina/Buenos_Aires, Europe/Monaco, or US/Pacific, as shown in the following code fragment. I'd just like to know what could determine which value is used? The device? The language?

  • SMS Gateway Devices

    - by u07ch
    Can anyone recommend a good SMS Gateway device that sends and receives messages and has a reasonable API. We are looking for a hardware device that a Sim Card and works with Windows / .Net. I am working with about 50 different countries (Right now 50 will only become more in the future) and dealing with that many SMS suppliers and their various methods for billing and sending / responding to messages is proving unmanageable. It may be much easier to have a single method and call it by country. We do bulk send messages but from the logs this is at most 500 messages at a time (though it could be up-to about 1500 at a time) - mostly its small numbers far less than 500 messages. Ideally would like to get message delivery data and error handling type messages back from the device. I am not interested in a hosted solution unless it has the ability to receive a message to a local number in EVERY country.

  • Windows Mobile Development on MacBook Pro?

    - by Ted Nichols
    I am a frequent Windows Mobile application developer in need of a new development laptop. I am considering a MacBook or Macbook Pro running either Fusion from VMWare or Parallels Desktop. This will give me the option to port my applications to the iPhone depending on what MS does with WM 6.5 and 7. Has anybody tried doing Windows Mobile development using Microsoft Windows Mobile Device Center (or ActiveSync) and VS2008 on the MacBook Pro using one of these virtual machines? Does the device emulator work properly? What about debugging a Windows Mobile device over a USB cable? In general, do most USB drivers (non HID) designed for Windows work under these virtual machines? Thanks.

  • Debug IPhone App on 3.1.2 Phone

    - by Steblo
    Hello, I recently finished my first IPhone app and want to test it on my device now. I registered (and paid) for an Developer Account and managed to install the required certificates. Unfortunately my device is on firmware 3.1.2 (which I don't want to upgrade). My SDK only shows 3.1.3 as possible Target. As a result it can't be installed on my 3.1.2 device. Where can I set/change to target platform ? Otherwise my App would only run on the newest firmwares, right ? Instead I want to provide it to every User with OS 3.0

  • Do I need to rebuild application after adding a new iPhone in ad hoc distribution?

    - by RaYell
    I'm using Ad Hoc distribution to send preview/beta version of my iPhone apps to customers for approval. I'm always sending a zipped application and mobileprovision files. Sometimes however I encountered situation when nothing in the application changed but we needed to add a new device for testing. I've added a device in Provisioning portal and assigned it to a provisioning profile my application uses for ad hoc distribution. I've downloaded new mobileprovision file and imported it to xcode now the question is do I need to rebuild the application to enable the app on a new device or would it be enough to just send old build with updated mobileprovision file?

  • What messaging technologies in windows-ce for gauranteed msg delivery?

    - by Aidanapword
    All, We are building a windows-ce (6.0R3) based device that requires guaranteed and audit-ready message delivery (including store & forward) up to and down from the cloud. I have been looking for choices beyond: MSMQ a proprietary solution (what our prototype device is using) AMQP (research on using this in our context is now starting) ... are there any others? We will be transporting sensitive data (who isn't?!?!) over a public network, and large scale options are required. Anything running on an embedded device will be performance sensitive too. Thanks!

  • Intelligent serial port mocks with Moq

    - by Padu Merloti
    I have to write a lot of code that deals with serial ports. Usually there will be a device connected at the other end of the wire and I usually create my own mocks to simulate their behavior. I'm starting to look at Moq to help with my unit tests. It's pretty simple to use it when you need just a stub, but I want to know if it is possible and if yes how do I create a mock for a hardware device that responds differently according to what I want to test. A simple example: One of the devices I interface with receives a command (move to position x), gives back an ACK message and goes to a "moving" state until it reaches the ordered position. I want to create a test where I send the move command and then keep querying state until it reaches the final position. I want to create two versions of the mock for two different tests, one where I expect the device to reach the final position successfully and the other where it will fail. Too much to ask?

  • my realtime network receiving time differs a lot, anyone can help?

    - by sguox002
    I wrote a program using tcpip sockets to send commands to a device and receive the data from the device. The data size would be around 200kB to 600KB. The computer is directly connected to the device using a 100MB network. I found that the sending packets always arrive at the computer at 100MB/s speed (I have debugging information on the unit and I also verified this using some network monitoring software), but the receiving time differs a lot from 40ms to 250ms, even if the size is the same (I have a receiving buffer about 700K and the receiving window of 8092 bytes and changing the window size does not change anything). The phenomena differs also on different computers, but on the same computer the problem is very stable. For example, receiving 300k bytes on computer a would be 40ms, but it may cost 200ms on another computer. I have disabled firewall, antivirus, all other network protocol except the TCP/IP. Any experts on this can give me some hints?

  • 3D Screensaver interfering with WPF application (Windows XP)

    - by Andrew Keith
    I have a fairly large application that uses WPF for its user interface. I recently found an unusual defect regarding 3D screensavers. The 3D screensavers 3D FlowerBox,3D Flying Objects,3D Pipes,3D Text causes 1 of my WPF windows to disappear when the screensaver activates. Other screensavers are fine. My application only encounters this problem on Windows XP. I have some experience with DirectX. When a 3D screensavers activates, the d3d device context will be switched to exclusive mode. I reckon that WPF has trouble restoring the device context when the device switches back to cooperative mode (hence why its only affecting windows XP) Has anyone seen such a scenario occur before ? Is there a remedy for the problem ? Windows XP SP3, DirectX 9.0c, .NET 3.5

  • WPF TreeView PreviewMouseDown on TreeViewItem

    - by imekon
    If I handle the PreviewMouseDown event on TreeViewItem, I get events for everything I click on that TreeViewItem include the little +/- box to the left (Windows XP). How can I distinguish that? I tried the following: // We've had a single click on a tree view item // Unfortunately this is the WHOLE tree item, including the +/- // symbol to the left. The tree doesn't do a selection, so we // have to filter this out... MouseDevice device = e.Device as MouseDevice; // This is bad. The whole point of WPF is for the code // not to know what the UI has - yet here we are testing for // it as a workaround. Sigh... // This is broken - if you click on the +/- on a item, it shouldn't // go on to be processed by OnTreeSingleClick... ho hum! if (device.DirectlyOver.GetType() != typeof(Path)) { OnTreeSingleClick(sender); } What I'm after is just single click on the tree view item excluding the extra bits it seems to include.
