May I know that after the generate a AC , what kind of information i need to pass to issue for verification ? Do i need to send my AC with PAN , PAN SN , CID and ATC to issuer for card identification ?
Thank you
David
Simple rule - data used during creation should be available during verification. The data elements used for creating GEN AC1 you can find from CDOL1. (another is to get it from Cryptogram version number, check based on context) These data you should make sure is passed to issuer. Card sequence number is not a part of CDOL1, but this has to be made available to the issuer( a common mistake).

I'm developing an OBD-II reader where I want to query requests to read PID parameters with a stm32 processor. I already understand what should go on the data field, but the ID is giving me a headache. As I have read, one must send 0x7DF to broadcast a request, and each ECU will respond with his own ID. However, I have been asked to do this within the SAE J1939 protocol, which uses the 29 bit extended identifier, and I don't know what I need to add to this ID.
As I stated in the title, could someone show me some actual data from a bus using this method? I've been searching on the internet for real frames but did not have any luck so far.
I woud also appreciate if someone could shred some light to if the OBD-II communication needs some acknowledgment to work properly.
Thanks
I would suggest you to take a look on the SAE J1939 documentation, in the more specifically on the J1939/21,J1939-71 and J1939/73.
Generally, a J1939 transport protocol response sequence can be processed as follows:
Identify the BAM frame, indicating a new sequence being initiated
(via the PGN 60416 - 0xEC00 can be reach by 0x1CECFF00 )
Extract the J1939 PGN from bytes 6-8 of the BAM payload to use as the
identifier of the new frame
Construct the new data payload by concatenating bytes 2-8 of the data
transfer frames (i.e. excl. the 1st byte)
A J1939 data transfer messages with ID 1CEBFF00 (PGN 60160 or EB00).
Above, the last 3 bytes of the BAM equal E3FE00. When reordered, these equal the PGN FEE3 aka Engine Configuration 1 (EC1). Further, the payload is found by combining the the first 39 bytes across the 6 data transfer packets/fram
The administrative control device or any device issuing the vehicle use status PID should be sensitive to the run switch status (SPN 3046 - 0xFDC0 which probably can be reach by 0xCFDC000) and any other locally defined criteria for authorized use (i.e., driver log-ons) before the vehicle use status PID is used to generate an unauthorized use alarm.
Also, you can't forget to uses a read/send to extend ID message, since that is a 24-bit.
In fact, i will suggest you to use can-utils to make your a analyses even easier. A simple can-dump or can-sniffer you can see what is coming on your broadcast.

Suppose there are 1000 Person agent on 4 (a,b, c,d) GIS region area. On a certain event, I want to communicate with all the agents living inside GIS region "a" . In "a" region we have 200 person agents.If I send message or command to Person state chart, how I can make sure that only those 200 person agents living on that specific GIS region "a" is getting my command? Is there any way to model that?
You can filter messages inside the Agent's statechart transition, in order to only executethe transition when a certain expression is true (in your case: Agent is in the right region).
Of course you could do this filtering in a lot of other places too, for example when sending the message, or when receiving it. However you can always use this code to check if the Agent is located inside of a GISRegion:
main.gisRegion1.contains(this.getLatitude(), this.getLongitude())
This is assuming you executed this inside the Agent (therefore main. and this.) and the region you are looking for is named gisRegion1.

webinar_id* {+}
It says string but when I input a string for webinar_id I get a 400 missing required parameter.
The linked document shows you that webinar_id is a string that is obtained by the call from section 1. Section 1 also specifies an array called schedules, and since the API call in question asks for an integer called schedule it is logical to assume this is the array of the index previously returned in the section 1 JSON response.
EDIT: webinar_id is also a string and schedule is also an int in the response from the call of section 2. I assume those will be identical to those from section 1.
The fact that {+} indicates re-using values from other requests is outlined in the subscript in section 3.
{+} webinar_id and schedule must be obtained from a previous API call to retrieve the details from whatever specific webinar you want to register the person to.
Hope that helps. It mostly just comes down to careful reading of the documentation document (which you should be glad you have, things aren't always this explicit!)
Just started coding with Appwarps and I'm running into an issue. I have a lobby built that shows live rooms, but I really do not want to show the rooms for matches that have already started. I figured I would use
void Client::setCustomRoomData(std::string roomId, std::string customData)
But I have some doubts on how to use it. Once the game starts, I plan on sending
SetCustomRoomData(roomId, "Closed");
to notify the server that open seating is now closed. However, when I check the room properties on another device when it calls
void CCAppwarpDelegate::onGetLiveRoomInfoDone(AppWarp::liveroom revent)
{
CCLog("CustomData=%s",revent.customData.c_str());
...
it returns blank. What am I missing here? Besides the code not working, what really makes me question myself is that I don't understand the mechanics of the properties. How do you have multiple custom properties since you aren't assigning it any kind of index...or do room only have a single custom property at any given time?
You don't need to use customData and instead use only room properties. Room properties is a set of key/value pairs that you can associate with a room.
I recommend you read the following link
http://appwarp.shephertz.com/game-development-center/matchmaking-basic-concept/
So the flow is as follows -
you first create the room using the createRoom API and pass a
properties dictionary containing <"closed", "false">.
Then once the game is active, you use updateRoomProperties API
on the room and pass <"closed", "true"> to the API.
Then when you want to show the list you should use
getRoomWithProperties and pass <"closed", "false">. This will get
you a list of rooms that are not yet "closed".
Hi I am working on a site and integrating authorize.net payment gateway. I am thinking of adding a dropdown for country names, will passing of "United States Of America" as country variable work? Or should I use "US"? Should I use ISO codes for every country? I tried on test developer account but it seems to accept everything I passes to it as correct!
~Ajit
I know authorize.net doesn't require country names. A simple way to see if they even validate them would be to run a transaction through the production gateway, pass a nonsense value and see if the transaction still goes through.
If you do standardize to support authorize.net (or for another reason), I'd suggest country codes versus full names. Codes seem to change less often, and also can be useful as identifiers. For example, I have an application which presents data for roughly 200 countries; I have flag icons (multiple sizes for each country) that use a 2 digit country code in their name. Using codes made this fairly easy to implement and maintain.
