I'm trying to add an lora device on Live Objects.
There is 'AppEUI' field on device registration form.
I don't know how to define AppEUI.
The FAQ explains:
The AppEUI and AppKey parameters are specific to the owner of the object and/or the application used with the object (see specification LoraWan).
And the LoRaWAN spec says:
The AppEUI is a global application ID in IEEE EUI64 address space that uniquely identifies the entity able to process the JoinReq frame.
So, i wonder if i can define appEUI for myself. I create my own EUI-64 address and just fill 'AppEUI' field of the form. Is that it?
Thank you.
yes you're right, you can define your own appEUI
best regards

I am developing rest api update method for user profile resource user/profile. I am disappointed what http method should i use. Update contains some required attributes so it more PUT request, where client need to fill all attributes. But how it can extend attributes in future. If i will decide to add new attribute then it will automatically clear because client is not implement it yet.
But what if this new attribute has default value or is set by another route?
Can i use PUT with not stricting number of attributes and use old data if new isn't come in request. Or how it can be done normally?
HTTP is an application whose application domain is the transfer of documents over a network -- Webber, 2011.
PUT is the appropriate method to use when "saving" a new version of a document onto a web server.
how it can extend attributes in future.
You design your schemas to be forward and backward compatible; in practice, what this means is that you can add new optional elements with reasonable default values. When you need to add a new required element, you change the name of the schema.
You'll find prior art in this topic by searching XML literature for must ignore.
You understand correctly: PUT is for complete replacement, so values that you don't include would be lost.
Instead, use the PATCH method, which is for making partial updates. You can update only the properties you include values for.
In our company, repository objects must be created with original language EN.
Is there a way to check the logon language in case of creating a new object in the ABAP repository?
Desired behaviour:
SE80 - Create program/class/data element/table/....
==> user exit/badi checks the logon language. When it is not 'EN', the creation will be refused.

I know there is a exit for this but I haven't remember exact name. You can use general purpose for finding exit. Go to SE24 and open CL_EXITHANDLER class, find GET_INSTANCE method and add break point. Then start creating item, it will pause on debugger multiple times, try to find suitable one.
As #mkysoft suggested, you may implement a check in the BAdI CTS_REQUEST_CHECK, method CHECK_BEFORE_ADD_OBJECTS, which is invoked when the object is about to be attached to a transport request. Raise the exception CANCEL to make the attachment fail (and so the object is not created too).
EDIT: sorry, ignore my answer, "this method is NOT released for Customer usage" as said in note 2150125 - Method CHECK_BEFORE_ADD_OBJECTS not triggered
DISCLAIMER: THE METHOD DESCRIBED HERE IS ABSOLUTELY NOT RECOMMENDED.
As correctly pointed out by the other members there is no standard and customer-exposed method to achieve your requirement, but if you absolutely must enable this check during creation you can use the below method. As well as the previously offered to you, it also involves modification of SAP standard.
There is a system BAdi CTS_TADIR_SUBSCREEN that is located inside enhancement point CTS_ES_TADIR_POPUP. They are SAP internal and not released for customer usage, so do this at your own risk.
Implementation procedure:
Step 0. First thing you need to change is a SAP internal usage flag, for which you need Object Access key which can be obtained from SAP or from SAP partner that made the implementation in your org. In virgin state this BAdi throws the error if you try to implement it
So hereinafter we assume that you already ticked off this checkbox in BAdi settings
Step 1.
In order to implement the BAdi one need to implement enhancement spot prior to that. This is the most complicated part, because despite we disabled internality flag the SAP-namespaced enhancements must be stored only in SAP-namespaced objects. By SAP namespace I mean non-Z, non-Y and non-T (Test). This means to implement this enhancement, besides modifying the enhancement definition, one need to create, for example, CTS_ES_TADIR named enh.impl., and save it to non-Z package, which you also need to create. Your enhancement implementations selector should look somehow like this
On the above screen only the second will work, all the rest Z will not.
Every non-Z object need Object Access Key, remember? Too bad. But just to show the proof-of-concept, I will proceed.
Step 2. After you created the enh. implementation in SAP-namespace it will propose you to create the BAdi implementation. The same principle applies here: only SAP-namespaced container for SAP-namespaced objects, hence CTS_TADIR_SUBSCREEN should have implementing class for example CL_TADIR_SUBSCREEN. During the creation of enhancement you will see many warnings
but finally you should have something like this, where all system-named objects are created and the enhancement/BAdi is activated.
Step 3. In order to get the BAdi working we need to enable this subscreen processing
during the playing with enhancement I found out that BAdi class is not being triggered standalone, without screen events not enhanced, so to make it work you need to touch a screen enhancement for screen 100
If you do not wanna modify screen elements logic, just put the dummy enhancement in SHOW_TADIR dialog module in the end of the include LSTRDO18
PROCESS BEFORE OUTPUT.
MODULE SHOW_TADIR. "<-- create the dummy enhancement here
CALL SUBSCREEN subs_info INCLUDING gv_badi_prog gv_badi_dynnr.
for example declaration statement like I did
Step 4. Activate your created BAdi class and put the necessary logic there. I wasn't able to trigger method GET_DATA_FROM_SCREEN, but PUT_DATA_TO_SCREEN worked fine
If we put this simple processing for your requirement
METHOD cts_if_tadir_subscreen~get_data_from_screen.
IF object_data-l_mstlang <> 'E'.
MESSAGE 'Objects in non-English languages are not allowed!' TYPE 'A'.
ENDIF.
ENDMETHOD.
it will not allow creating objects in languages other than English.
The check in method get_data_from_screen is being done before showing the screen so language is determined from system logon settings. If to play more with this BAdi, I suppose the method GET_DATA_FROM_SCREEN can also be enabled, which will make it possible to check user input, i.e. the case when the user gonna change the default language.
I have to create a particular simulation for a college project. The simulation should feature several mobile nodes cyclically switch between 802.11 access point and station modes. While in station mode, nodes should read the SSIDs of access points around them, and then they should change their SSID in AP mode accordingly. There is no need for connections or data exchange between the nodes beside the SSID reading.
Now, I've been through Omnet/Inet tutorials/documentation (all two of them), and I feel pretty much stuck.
What I could use right now is someone confirming my understanding of the framework giving me some directions on how exactly I should proceed.
From what I understand is Inet does not implement any direct/easy way to do what I'm trying to do. Most examples have fixed connections declared in NED files and hosts with a fixed status (AP or STA) defined in the .ini file.
So my question is basically how do I do that: do I need to extend a module (say, wirelessHost), modifying its runtime behaviour, or should I implement a new application (like UDPApp) to have my node read other SSIDs and change his accordingly? And what is the best way to access an host's SSID?
You may utilize two radios for each mobile node e.g. **.mobilenode[*].numRadios = 2 (see also example in /inet/examples/wireless/multiradio/).
The first radio operates as AP **.mobilenode[*].wlan[0].mgmtType = "Ieee80211MgmtAPSimplified" which has to adapt its SSID.
The second radio serves as STA **.mobilenode[*].wlan[1].mgmtType = "Ieee80211MgmtSTA". Now, you have to sub-class Ieee80211AgentSTA which handles the SSID scanning procedure and has to change the first radio's SSID upon new SSID detection. Then you utilize the adopted sub-class within the simulation. Finally, active scanning has to be activated **.mobilenode[*].wlan[1].agent.activeScan = true.
First, thanks for any advice. I am new to all of this and apologize for any obvious blunders.
Second, the question:
In an interface for entering clients that often possess a number of roles, it seemed efficient to create a set of inputs which possessed both visual characteristics and associated data binding based simply on the inputs name.
For example, inquirerfirstname would be any caller or emailer who contacted our company.
The name would dictate a label, placeholder, and the location in firebase where the data would be stored.
The single name could be used--I thought--with a relational table (state machine or series of nested ifs) to define the properties of the input and change its outward appearance and inner bindings through property manipulation.
I created a set of nested iffs, and console logged the property changes in the inputs, but their representation in the host element (a collection of inputs that generated messages to clients as well as messages to sales staff) remained unaffected.
I attempted using the ready callback. I forced the state change with a button.
I was unable to use the var name = new MyInput( name). I believe using this method would be most effective but am unsure how to "stamp" the JavaScript into a heavyweight stamped parent element.
An example of a more complicated and dynamic use of a constructor and a factory implementation that can read database (J-son) objects and respond to generate HTML elements would be awesome.
In vanilla a for each would seem to do the trick but definitions and structure as well as binding would not be organic--read it might be easier just to HTML stamp the inputs in polymer by hand.
I would be really greatful for any help. I have looked for a week and failed to find one example that took data binding, physical appearance, attribute swapping, property binding and object reading into account.
I guess it's a lot, but each piece independently (save the use of the constructor) I think I get.
Thanks again.
Jason
Ps: I am aware that the stamping of the element seems to preclude dynamic property attribute and binding assignments. I was hoping a compute attribute mixed with a factoryimpl would be an option (With a nice example).
Currently I'm using trial version of RFT for PowerBuilder v12.5 application. During recording when we save one windows information it generate a string (unique auto generated) for variable and use it for reference to store all other information from other windows and tabs . Currently RFT use this in Object Map for reference and when we playback the script, it fails as value of the variable changes from recorded value. I am unable to change recognition properties so that during playback it does not match above variable ‘Business Partner ID’.
I need to know how I can change the recognition property so that during playblack RFT skip the matching of this value or how can I make this dynamic so that whenever during playback RFT save the information it get the unique value each time.
Your prompt response will really help me a lot, thank you in advance. In case any other details required, do let me know.

Atif Abbas
In cases where recognition properties of an object are dynamic , there are two approaches two handle them:
Convert the dynamic property value to a regular expression.
Convert the object itself to a dynamic test object.
You can find detail information on converting the property value to a regular expression in the below link.
http://publib.boulder.ibm.com/infocenter/rtnlhelp/v6r0m0/index.jsp?topic=%2Fcom.rational.test.ft.help%2FReplExactMatchPropwithPattern.htm
Also there is a nice blog on object map of RFT:
http://rftobjectmap.blogspot.in/
If you want to find objects with changing properties you can consider to use the TestObject.find method. This allows you to access test objects without even having them in the object map. A good introduction to the find method is provided by IBM developerWorks: http://www.ibm.com/developerworks/rational/library/06/0711_nowacki_nodwell/.
