I've been trying to run valueReporting simulation using castalia. I've edited the ini file in ordre to add to a node 2 sensor devices ( weight and blood glucose). However i'm facing the following error running the simulation :
Error in module (SensorManager) SN.node[0].SensorManager (id=10) during network initialization: Model error:
[Sensor Device Manager]: The parameters of the sensor device manager are not initialized correctly in omnet.ini file..
Here's a sample of the omnetpp.ini file. omnetpp.ini
Does anybody have any idea why i'm having this error ? if so, how can i fix it ?
Thank you !
If you searched for the error message The parameters of the sensor device manager are not initialized correctly in omnet.ini file in the code you would find it in SensorManager.cc.
You could then figure out that this error is triggered when any of 9 parameters do not match the number of sensor devices you have on the node. These are the 9 parameters:
SN.node[0].SensorManager.sensorTypes
SN.node[0].SensorManager.corrPhyProcess
SN.node[0].SensorManager.pwrConsumptionPerDevice
SN.node[0].SensorManager.maxSampleRates
SN.node[0].SensorManager.devicesBias
SN.node[0].SensorManager.devicesNoise
SN.node[0].SensorManager.devicesSensitivity
SN.node[0].SensorManager.devicesResolution
SN.node[0].SensorManager.devicesSaturation
You only define the first two correctly in your ini file. All the rest have the default values, which include only one sensor type, you need to include two values for each. You can look at SensorManager.ned to see what are the default values that these parameters take. You can then simply copy these values, or change them according to your needs.
For example devicesNoise default value is "0.1", so for two sensing devices it can be "0.1 0.1"
I am running a code for my FPGA to collect data from accelerometer and I am able to print that to Tera Term. And I followed this tutorial to have MATLAB plot the data in real time.
I have essentially used the same code except a few changes in variable names title.
It gives me the following error.
The mathwork website has a similar question posted but there is no solution.
Open failed: Cannot connect to the COM6 port. Possible reasons are
another application is connected to the port or the port does not
exist.
Error in Untitled (line 8) fopen(s);
TIA
I've started using V-Rep to simulate some robots (Pioneers and quadrotors, initially), but I've been having problems when I try to connect it with ROS. I tried to replicate the example from RosTopicPublisherAndSubscriber.ttt and it only works the first time, after I close it and load it again, it doesn't work anymore, my code is practically identical to the example, except that I use getPose and it's a Pioneer (the one that comes with V-Rep), here's my code:
if (simGetScriptExecutionCount()==0) then
-- Check if the required plugin is there (libv_repExtRos.so or libv_repExtRos.dylib):
local moduleName=0
local moduleVersion=0
local index=0
local pluginNotFound=true
while moduleName do
moduleName,moduleVersion=simGetModuleName(index)
if (moduleName=='Ros') then
pluginNotFound=false
end
index=index+1
end
if (pluginNotFound) then
simDisplayDialog('Error','ROS plugin was not found.&&nSimulation will not run properly',sim_dlgstyle_ok,false,nil,{0.8,0,0,0,0,0},{0.5,0,0,1,1,1})
else
-- Retrive the handle of the vision sensor we wish to stream:
lHandle=simGetObjectHandle('Pioneer_p3dx')
-- Now enable topic publishing and streaming of the vision sensor's data:
topicName=simExtROS_enablePublisher('p3dx',1,simros_strmcmd_get_object_pose,lHandle,0,'')
if (topicName == nil) then
simDisplayDialog('Error','Nil',sim_dlgstyle_ok,false,nil,{0.8,0,0,0,0,0},{0.5,0,0,1,1,1})
else
simDisplayDialog('Error','Not Nil',sim_dlgstyle_ok,false,nil,{0.8,0,0,0,0,0},{0.5,0,0,1,1,1})
end
-- Retrive the handle of the passive vision sensor. We will use the passive vision sensor
end
end
Any idea is welcome! Thanks in advance!
PS: Also, if anyone with 1500 reputation points could create the v-rep tag, that would be great!
Ok, the people at V-REP helped me solve it. So basically I should used the argument as -1 instead of 0.
So basically, a should have done this
topicName=simExtROS_enablePublisher('p3dx',1,simros_strmcmd_get_object_pose,lHandle,-1,'')
instead of
topicName=simExtROS_enablePublisher('p3dx',1,simros_strmcmd_get_object_pose,lHandle,0,'')
I'm trying to follow this guide on sending data from an arduino to a MATLAB program. I have every piece of code exactly matching the code in the example. However, whenever I attempt to start up the MATLAB program, I get the error message:
Error using serial/fopen (line 72) Open failed: Port: COM3 is not
available. Available ports: COM1. Use INSTRFIND to determine if other
instrument objects are connected to the requested device.
Error in Untitled8 (line 2) fopen(arduino)
Can anyone help me figure out how to get this working?
EDIT: My arduino is printing to COM3, so if I want MATLAB to hear it, it also needs to be COM3.
If I understand correctly you are using the Arduino IDE/Monitor to communicate with your Arduino on COM3. You want to have Matlab connect to the Arduino.
Since RS-232 is a point to point methology, you can only have one program/device on each end unless you add a bunch of hijinks.
When you have the Arduino IDE/Monitor open it uses the com port and other programs are denied access.
I think you need to close the Arduino monitor program to release Com port 3 and then the Matlab program should be able to open the port.
I am a newbie . we are using NXP 's jn518 ek 010 and I am using jennet stack .
we are using win 7 and for application development we are using eclipse .
our project task is to get the temperature , humidity and luminosity sensors value on PC , from which decision making will be proceeded.
can any one guide me how to get these values in human readable format?
I have read about the custom flash programmer which provide these functionality but they were limited to jn5139.
2 )Is it can be done by the help of wireshark?
3 ) can I get values with the help of hyper terminal?
Thanks in advance.
