Is there a set of functions to disable/enable messages in a CANoe simulation using CAPL?
I have a node called ECM_LS that sends a message Engine_Test_Information_LS on my simulation, and I want to write a test that disables ECM_LS and ECM_LS::Engine_Test_Information_LS. Once I saw a function like disableNode() or canNodeOffline() but I do not remember clearly.
You do not need to disable whole node, you can just stop sending single message.
Function for disabling is TestDisableMsg():
long TestDisableMsg (dbMessage aMessage)
long TestDisableMsg (dword aMessageId)
long TestDisableMsg (char aMessageName[])
In your case it would be TestDisableMsg(Engine_Test_Information_LS);
And you can enable sending of message with TestEnableMsg(Engine_Test_Information_LS);
Or if you really need to disable whole node, you can use ILNodeControlStop and ILNodeControlStart for restarting:
long ILNodeControlStart(char aNodeName[])
long ILNodeControlStop(char aNodeName[])
Yes you can....!
if you are using ILconfiguration you use
1)ILDisableMsg() function in network node.
2)For enable use ILEnablemsg().
Suppose if you are using the test module node
1)testDisableMsg (dbMessage aMessage); in test module node
2)testEnableMSg(); for enable again the message.
Suppose if you are Using normal config(withoutil)
simply create a constant and use if condition. If that condition is ture dont

I want to know if some API/code exists to disable a specific item in the (current) network connection properties?
If yes, could you show a working code example, explain the details, and point out some limitations (if they exist) of the technique used?
The API to disable these bindings is INetCfgBindingPath::Enable. The bindview sample illustrates how to call the API.
From Windows 8 and later, you may alternatively invoke the WMI method /root/standardcimv2/MSFT_NetAdapterBindingSettingData::Disable. Here's a line of PowerShell that illustrates how to disable the bindings from a NIC named "mb-port" to the "ms_msclient" driver (aka wkssvc):
Get-CimInstance -Namespace root/standardcimv2 -Query 'SELECT * FROM MSFT_NetAdapterBindingSettingData WHERE Name = "mb-port" AND ComponentID = "ms_msclient"' | Invoke-CimMethod -MethodName Disable
Note that the GUI is being sneaky: it merges multiple bindpaths into the same checkbox. In the example you have highlighted, there are likely 2 bindpaths from ms_msclient to the NIC: one over IPv4 and one over IPv6. The GUI disables/enables all paths when you clear/tick the checkbox. If you come in through the API and want to do the same, you'll need to enumerate all bindpaths that start from ms_msclient and go to the NIC mb-port.
During my test on Pepper, I found some difficulties in realizing continuative collaborative dialog.
In particular, after about 10 minutes, it seems that the ALSpeechRecognition engine stops working.
In other words, Pepper dialog panel remains empty and/or the robot does not understand my words, even if the structure worked some minute before.
I tried to stop and restart it (i.e., the engine) via SSH terminal, by using:
qicli call ALSpeechRecognition.pause 1
qicli call ALSpeechRecognition.pause 0
It should restart the engine according to the guidelines shown here, but it does not work.
Thank you so much guys.
Sincerely,
Giovanni
According to the tutorial, starting and stopping the speech recognition engine is done by subscribing/unsubscribing it.
The recommended way to do this is unsubscribing and subscribing back to it. For me it also worked changing the speech reco language and chaging it back to the one you had previously.
Luis is right and to do so just create a function as below given and call it if ActiveListenning event comes false from ALSpeechRecognition module. Note: Use ALMemory module to get data from ALSpeechRecogntion.
asr_service = ALProxy("ALSpeechRecognition",ip,port)
memory = ALProxy("ALMemory",ip,port)
def reset():
asr_service.unsubscribe("ASR_Engine")
asr_service.subscribe("ASR_Engine")
ALS = memory.getData("ALSpeechRecognition/ActiveListening")
if ALS==False:
reset()
How do I make the script wait for the bridge to terminate before continuing when I have "bypass_media" set to true?
This snippet -
freeswitch.consoleLog("err","session before="..tostring(session:ready()).."\n")
session:execute("set","bypass_media=true")
session:execute("bridge","sofia/gateway/carrierb/12345678")
freeswitch.consoleLog("err","session after="..tostring(session:ready()).."\n")
from an audio perspective, it works perfectly with bridge_media set to either true or false, and a wireshark trace shows the audio either passing through (false) or end to end (true).
But with bypass set to true, the script continues without pausing, and the session is no longer ready (session:ready() == false).
The channel seems to go into a hibernate state, but I have housekeeping to do after the bridge is finished which I simply cannot do.
Same happens if i do the bridge in XML dialplan, immediately carries on causing my housekeeping to fire early.
FreeSWITCH (Version 1.6.20 git 43a9feb 2018-05-07 18:56:11Z 64bit)
Lua 5.2
EDIT 1 -
I can get "api_hangup_hook=lua housekeeping.lua" to work, but then I have to pass tons of variables and it fires up a new process/thread/whatever, which seems a little overkill unless that's the only way.
I have a workaround, but would still like an answer to the question if anyone has one (ie how to stop the bridge exiting immediately).
If I set this before the bridge :
session:execute("set","bypass_media=true")
session:execute("set","session_in_hangup_hook=true")
session:execute("set","api_hangup_hook=lua housekeeping.lua "..<vars>)
then "housekeeping.lua" fires when the bridge actually terminates (which is long after the script does).
In housekeeping.lua I can then do :
session:getVariable("billmsec")
and it seems to have the correct values in them, allowing me to do my housekeeping.
My problem with this is the uncertainty of playing with variables from a session that appears to have gone away from a script that fires at some point in the future.
Anyway, it'll have to do until I can find out how to keep control inside the original script.
I'm using LabVIEW and its VISA capabilities to control a Keithley 2635A source meter. Whenever I try to identify the device, it works just fine, both in reading and writing.
viWRITE(*IDN?) /* VISA subVI to send the command to the machine */
viREAD /* VISA subVI to read output */
However, as soon as I set the voltage (or current), it does so. Then I send the command to perform a measurement, but I'm not able to read that data, with the error
VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.
After that, I can not read the *IDN? output either anymore.
The source meter is connected to the PC via a National Instrument GPIB-USB-HS adaptor.
EDIT: I forgot to add, this happens in the VISA Interactive Control program as well.
Ok, apparently the documentation is not very clear. What the smua.measure.X() (where X is the needed parameter) command does is, of course, writing the measurement outcome on a buffer. In order to read that buffer, however, the simple viREAD[] is not sufficient.
So basically the answer was to simply add a print command: this way I have
viWRITE[print(smua.measure.X())];
viREAD[]
And I don't have the error anymore. Not sure why such a command is needed, but that's that. Thank you all for your time answering me.
As #Tom Blodget mentions in the comments, the machine may not have any response to read after you set the voltage. The *IDN? string is both command and query. That is, you will write the command *IDN? and read the result. Some commands do not have any response to read. Here's a quick test to see if you should be reading from the instrument. The following code is in python; I made up the GPIB command to set voltage.
sm = SourceMonitor()
# Prints out IDN
sm.query('*IDN?')
# Prints out current voltage (change this to your actual command)
sm.query('SOUR:VOLT?')
# Set a new voltage
sm.write('SOUR:VOLT 1V')
# Read the new voltage
sm.query('SOUR:VOLT?')
Note that question-marked GPIB commands and the query are used when you expect to get a response from the instrument. The instrument won't give a response for the write command. Query is a combination of write(...) and read(...). If you're using LabView, you may have to write the write and read separately.
If you need verification that the machine received your instruction and acted on it, most instruments have the following common commands:
*OPC? query to see if the operation is complete
SYST:ERR? query to see if any error was generated
Add a question mark ? to the end of the GPIB command used to set the voltage
Using Delphi 7 I am reading from a serial port.
The read is always preceded by a write which triggers the h/w to measure from a sensor and write something for me to read (and there is always something to read).
I have two possibilities: manually enter a command and click a button to write that to the serial port (read model or f/w version, etc) or click a button to loop reading measurements until a stop button is pressed. These both use the same internal functions, so the code looks something like this:
WriteSerial('?model');
SerialData := ReadSerial(); // returns string
WriteSerial('?fw');
SerialData := ReadSerial();
and
while stopButtonNotPressed do
begin
WriteSerial('?data');
SerialData := ReadSerial();
Memo1.Lines.Add(SerialData );
end;
The first variant (manually entering a command & pressing a button) is always successful, no matter how quickly or slowly I enter commands (hold down button for repeat), where are the second goes
pass
fail
pass
pass
fail
pass
pass
fail
... add infinitum
adding calls to sleep produces nothing, but trying to debug, I found that if I add a modal dialog box MsgDialog, 'Please close this dialog...', mtInfo, [mrOK]); to the loop, then it no longer fails.
Now, it doesn't look like timing (else surely adding Sleep(2000); to the loop would make it pass & does not, so why does pressing a button on the main form or the modal dialog cause it to succeed?
Btw, the h/w user guide says nothing of CTS / RTS, and the sole code example provide also does not.
Note: if I manually enter ?data repeatedly it never fails ...
Any ideas?
Your serial devices need time to react, so obviously you need a break for the device to catch up. When you use the keyboard to push the button you're providing the brake it needs because the keyboard repeat isn't all that fast.
As you say Sleep(2000) should provide plenty of "break", but there are two other potential problems you'll need to take care of:
Serial communication isn't necessary buffered: Sleep(2000) might be too long!
The serial library you're using might be using windows messages to process incoming bytes. Sleep() inhibits the message pump, so no more messages flow towords your application
Try "sleeping" using something like this:
procedure BusyWait(ms: Cardinal);
var StopAt: TDateTime;
begin
StopAt := Now + EncodeTime(0, 0, ms div 1000, ms mod 1000);
while StopAt > Now do
begin
Application.ProcessMessages;
Sleep(50); // per Michał Niklas's suggestion, to keep the CPU from reaching 100%
end;
end;
This routine will wait, but it'll keep the message pump going, allowing your serial library to receive messages. If that's the problem...
Maybe adding Application.ProcessMessages() before Sleep() will help.
