Problem about Communication with Bluetooth
Hi all!
I want to use a PC host to communicate with a mobile phone with Bluetooth technology. In details, the mobile phone wanting to know some informaiton about "news of today" firstly send a message to my PC, then my PC have to response with a reply message to that client mobile phone. It seems that I should use Java programming with J2SE to control the communication through Serial Port. Is it right? I want to overview some Java sample code about this topic so that I'm able to know the general manipulation. Thanks very much! : )
Hi,
Under J2ME you can use the JSR82 but only for compiling and then port the application on the mobile device. The source is not implemented.
There is free APIs java that you can use www.javabluetooth.org
Let me know if it works with you, I am going to begin next week...
Sihem ;)

Problem of communication with compactrio
Hello,
I am working with a compactrio 9014 and labview 8.5
I have a problem of communication with my compactrio. I acquire sound with NI 9215 and transmit points from the fpga VI to the VI on the real time target at a rate of 10Khz. On the VI on the RT I have two loops, one determinisic running at a speed of 10Khz (0.1ms) (in this loop I will do my signal processing) and one non-deterministic running much slower (20ms) to communicate data to my computer. To communicate data to my PC, I used shared variable.
The problem is that if I run the VI_RT, I loose immidiately the connection. I think that is because the VI is taking up all of the execution time of the
processor and is starving out the communication loop that is used to
send data back to my PC.
Because of this problem, I try to configure my compactrio to automatically run on startup of my cRIO. So I follow the steps I have read in another message in the forum posted by MattP
To make your application (RT host VI and FPGA VI) run automatically on startup of your cRIO, you will need to do the following:
1. Download the FPGA VI to the flash memory on your cRIO. If
using LabVIEW 8, right-click on the VI in the Project Explorer Window
and select Download VI or Attributes to Flash Memory...
2. Build an executable out of the RT VI. Under your RT target
in the Project Explorer, right-click on Build Specifications and select
New>>Real-Time Application. Select the source files necessary
for your application and any support files to be included. Click Build.
3.. After building the RT Application, you will find its entry
under the Build Specifications folder in your project. Right-click on
the application and choose Set as startup. Right-click again and
choose Deploy, which will download the application to your cRIO.
With this procedure, I thougt that I can run my loop faster because I don't have the RT VI open on my desktop (PC), so the PC don't have to synchronise the VI. But when I startup my compactrio, I loose connection with the target...
So, what is wrong with my project? Is it possible to run a loop at 10kHz on the real time processor and communicate in the same time (but every 20ms) data to my PC. Can someone explain me the right procedure to do that at this frequencies?
I have attached my project and hope that someone can help me.

Communication.zip 658 KBHello,
The method you use in your application to transfer the data from the FPGA to
the RT Host use the Front Panel Interactive Communication that write/read the
control/indicators of the FPGA VI. This method provides also risk of Race
Condition and use uP resources.
To avoid errors in data caused by race conditions and use less processor resources,
I suggest you to rewrite this part of your application with the method
DMA transfer from FPGA to Host.
You will find some good tutorial at the following address.
What
is the Best Method For Synchronizing a LabVIEW FPGA and a Host Interface VI?

Question about Communication with Oracle 7
Hi,
Generally we use Oracle Snapshots for Communication, but since Oracle 9.2.0.5 do not work with Oracle 7.1.5.2.4. we are thinking about do use Oracle Interconnect for this Link.
Now I have the following two Questions about Communication with Oracle 7:
1. Is an Adapter for Oracle 7.1.5.2.4 available?
2. From your experience, does it make sense to install Oracle Interconnect for implementation of only one read only Link with 3 Tables if an OAS for BI is available?
Thanks,
Hannes1. The Oracle database adapter is for Oracle 8i and up. I checked the code needed in the database and doubt that will work in Oracle 7.
1. The other option Advanced Queuing also needs 8i and up.
2. For me it doesnt make sense that you want to connect to Oracle 7. Oracle 7 is unsupported and should not have to be developed against. Also the license costs for Oracle Interconnect ~17K without any discount is a bit steep for read only links to three tables. Having the OAS means you wont have to pay another additional ~17K for the apps server. -
Lenovo S820 problem in call with bluetooth headset
Hello All.
I have Lenovo S820. I update smartphone to last version firmware. Information from phone:
Model: Lenovo S820_ROW
Android system version: 4.2.1
Firmware communication module: S820.V21, 2013/08/07 15:14
Build number: S820_ROW_S119_130922
I also connected the bluetooth headset. In the phone attached 2 sim: MTS(3g and 2g), BWK(only 2g)
Problem:
When I call from first slot of sim with bluetooth before whistles Lenovo S820 activate flight mode and disconnect with all providers(MTS and BWK) and after reset call Lenovo S820 turn off flight mode.
In second phone I recive call, but I can't answer a call from Lenovo S820.
I try from different headsets. this problem occur with all headsets.try to update your firmware with the latest ROW version
[#Update]#Lenovo #S820 with the Latest ROW Version Firmware S221

Problem while communicating with ECU through NI USB CAN
Hello sir,
I want to communicate with ECU through NI USB CAN interface while i tried to communicate with ECU it gives timeout error. here i am using CCP version 1.0, ECU toolkit 2.1.4 and NI CAN 2.7.2 .if you have any problem that communicates with ECU using CCP version 1.0 Please attach it.
Thanks and Regards,
MadhanSo for the fifth time you start a new thread about the same problem!
If you don't get any response to your threads, it could be because you are not giving a lot information about your problem.You could start with giving the vi you have problem with, so that we can see what you are doing.
You also need to give any error code and a description on that you have done, in details!
You also had one response in one of the other threads, it is polite to make an answer when someone is replying to you.

That makes no sense, where have you copied that from ? -
Long string problem while communicating with DLL
Hi
In our project, we encountered problems about passing strings longer than 255 characters while the SAP system communicates with a dll method.
We do not want to use file operations as the intermediary layer. Is there a way to handle this situation other than a file-related solution?
Thanks & Regards...

Sorry for answering late. The dll is created via VB. At the ABAP side, a type having length greater than 255 or the string type gives error. This seems to be a restriction of OLE interface?
Thanks...

OEM Problem in Communicating with Listener
Dear all,
for some reason, my OEM is corrupted and when it's enabled, it messes up with the listener. I concluded the problem lies in OEM rather than in the listener since I can establish connection between SQLdeveloper and the server via the listener without any problem.
I have instance named INARA, host named FIREFLY.SNOWDROP.COM, and listener named ORACLE_LISTENER.
I closed SQLdeveloper application and its listener and started OEM first to pinpoint the problem. After I started OEM, the Management Service log emoms.log dumped:

Any idea how to troubleshoot the problem from this point?
regards,
ValHi SyBrand,
sorry if you got impression that I'm ignoring pointers that you gave me. I assure you that I'm trying to use the pointers that everyone gave to me and I really appreciate it.
I'm still learning how to get familiar with the database, read the log file, troubleshoot the problems, and get familiar the whole concept, that's why most of the time I receive wrong message from everyone, most often I detect them incorrectly.
Ok, so far what I understand is I have a database resides in the server, a client, and a listener. The client, in this case, OEM is connecting to the server via listener. In my listener.ora configuration, there are 2 listener configuration, LISTENER and ORACLE_LISTENER. In the client side whose description is in tnsnames.ora it has inara as client service name, which should be matched with available listener either with LISTENER or ORACLE_LISTENER.
one of the log file that says connecting to 192.168.1.5 is because it implicitly translated firefly into its ip address which is 192.168.1.5.
Also I double check both files as you suggested before listener.ora
# listener.ora Network Configuration File: /usr/local/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
ORACLE_LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
ADR_BASE_LISTENER = /usr/local/oracle
ADR_BASE_ORACLE_LISTENER = /usr/local/oracletnsnames.ora
# tnsnames.ora Network Configuration File: /usr/local/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
INARA =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = inara.snowdrop.com)
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl.snowdrop.com)
LISTENER_OCA11G =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)service inara in tnsnames.ora is consistent with LISTENER or ORACLE_LISTENER.
How can I associate local service name inara with OEM client? BTW OEM client and database reside in the same host firefly.

Problem about NetGroup with Cirrus
Hi guys, I try to setup NetConnection and NetGroup following the example code in tutorial "Peer-assisted networking using RTMFP groups in Flash Player 10.1" ( http://www.adobe.com/devnet/flashmediaserver/articles/p2p_rtmfp_groups.html ) but have got some problems. No matter how many node I connect to the same netgroup, estimatedMemberCount and neighborCount is always 1 and 0. I can receive NetConnection.Connect.Success and NetGroup.Connect.Success event and calling NetGroup.post does return a vaild id but still, nobody could receive a NetGroup.Posting.Notify. Any idea what may be wrong or missing ? Thanks.
I have the same problem... what do you mean with "wrong version of playerglobal.swc"? Thanks

Problem when communicating with postgres
Hi everyone,
i have got a problem when i am trying to communicate with postgres.

i am really confused, what is the mistake i made? .
please help and its urgent. thanks
harish.Hello Harish,
I was introduced to databases at university with postgres. I now use SQL Server 7.
Anyway, what is the problem exactly - which exceptions are being thrown?
I have to admit, these forums don't present code very well and it makes it more confusing to read.
What are you inserting into your database - what is the context of your application ?
I did notice your constructor will be treated like a method. It does not matter in this case as it doesnt do anything, but you can't have void or any return type in your constructor - it has implicit instructions to return an instance of this class when it is called. If it is empty, omit it altogether.
I understand you getConnection() method.
I've never used the prepared statement:
String sql = "INSERT INTO exception_ip_list (ip_Address)" + " VALUES (?)";
PreparedStatement pstmt = con.prepareStatement(sql);
pstmt.setString(1, ipAddress);I assume the '?' in the sql string gets replaced with 'ipAddress' parameter variable? Are you sure 1 is the correct number - I know sql counts from 1 but java counts from 0.
You have created statement st and haven't used it, but later created st1 ?
For your JSP's, try
test0.jsp
<%@ page language="java"%> <!-- this is not needed -->
<html>
<head>
<title>
</title>
</head>
<body>
<form name="exiplist" method="post" action="test1.jsp">
<input type="text" name="ip"><br>
<input type="submit" name="SUBMIT" value="SUBMIT">
</form>
</body>
</html>
test1.jsp
<%@ page language="java" import="java.sql.*, Harish.*" %> <!-- this is not needed -->
<jsp:useBean id="exiplist" scope="page" class="Harish.Exception_IP_List" />
<html>
<body>
<%=request.getParameter("ip")%><br>
Inserted: <% int i = exiplist.insertExceptionIPList(request.getParameter("ip")); out.print(i); %>
</body>
</html>
Please let me know how this works,

Difficulty about communication with an instrument
hi,
I have a instrument which can measure voltage .According to the Getting Started with Labview,I could not communicate with it yet?
what should I do?
what the reference to look?Sorry again............your info is not really helpful.........
with Google I only found a "Door closer" Type UA304.
Find attached a vi - made for HP34401-DMM connected via GPIB;
maybe this gives an impression, how to handle such kind of
instrument.
Hope this helps.
