EXCO Members’ Directory for Visiting Delegates

To: EXCO Members of Youth Committee
From: K.L. Ng

Re: Exco’s Directory for Visiting Delegates

I have attended 2 networking/reception functions:-
1) MRCA
2) CMA of Hong Kong

Here is my feedback:-
– CMA of HK had given us delegates booklet, it will be good if we can give them a EXCO’s or Youth Committee Directory.

Purpose:-
– they can get to know us better and can have something to take back with them.
– with directory they can know our business and explore business opportunities

Cost of Directory:-
– cheapest solution = use A4 paper and colour printer to print the directory
– professional solution = print in booklet

How to Create Directory Using Cheapest Solution:-
– extract from KLSCCCI Membership Directory
– put in MS Word table format

The directory can also be given to MBA students from Philippines during their visit on 30/Oct.

TROUBLE SHOOTING STEPS : Please answer all questions:-

  1. Create a Java project/new code without thread, does it work?
    Answer:   Yes   /   No
  2. If “no”, then try the code (no thread) in 32 bit OS, does it work?
    Answer:   Yes   /   No
  3. If “no”, then what is the STK API function that you called that result the error?
    Answer:  
  4. Try in 32 bit, no thread and change the JRE to “JavaSE1.6” (refer screen shot below), does it work?
    • Untitled 2
    • Answer:   Yes   /   No
Final Solution: 1. your Java code must follow strictly the “STK API FLOW CHART” in page 12 of the manual, “MOBITEK STK API version 6.pdf”. Refer figure below for the flow chart;

STK API FLOW CHART
Untitled

2. your Java code must call STKStatusGet() and wait for a response moving moving to next step, i.e sequential

3. your Java code must call “MobitekSTKAPI.dll” (STK API) in synchronous manner, i.e. you must wait for a response from STK API before calling another function;

4. DO NOT call “MobitekSTKAPI.dll” (STK API) in asynchronous manner, i.e. your Java code make mutiple calls to STK API without waiting for any response as this will cause your code, API or modem to crash.

 

“OK” Bug in MOBITEK STK API version 6.3

Product:
  1.  MOBITEK Q24 STK MODEM HUB
  2. MOBITEK STK API version 6.3

Which programming language are you using?

  • JAVA
  • JRE version: 8
  • JACOB versio: 1.14.3

OS

  • Windows 7, 32 bit
  • Windows 7, 64 bit
SIM CARD: M-PESA
Description of Problem: 1) The menu is not submitting when it get to the end of the flow. On Android, the menus shows a message saying “sending…”, which stays on for few seconds, before presenting a confirmation box with “Ok” and “Cancel” buttons.

2) The menu fails to submit any value which starts with “Ok”. Some customers have names (first name, last name) starting with “Ok”. Example “Okie”.

TROUBLE SHOOTING STEPS : Do you have anyone with name with just 2 letters — “OK” ?

So far we have not encountered anyone with the name just OK.

Note:-

  • Please note the this “OK” bug will only affect your old batch of SIM cards and NOT your new batch.
  • Because old batch is using text format, new batch is using UCS2 format for names.
Final Solution:
  • Uninstall MOBITEK STK API version 6.3
  • Download a zip file:-
    • web browser will prompt for login, enter:
        • username = all
        • password = wemakesystemstalk
  • Install version 6.4, it fixes “OK” bug
  • IMPORTANT NOTE: if anyone with the name “OK” then the API will not submit it as a name but rather as a confirmation.


How to Write a Multi-Threaded Java Code with MOBITEK Q24 STK API

SUMMARY OF SUPPORT for MOBITEK Q24 STK MODEM



 

Product:
  1.  MOBITEK Q24 STK MODEM HUB
  2. MOBITEK STK API version 6.3

Which programming language are you using?

  • JAVA
  • JRE version: 7.0-b147
  • JACOB versio: 1.14.3

OS

Windows 7, 64 it
SIM CARD: M-PESA
Description of Problem: We are unable to start multiple modems at once. We have written our application using JAVA, and we are using threads for each modem. The first one works fine, but the next ones fail to connect. The application complain about access.
Final Solution: We do no have Java programme in our team. We will try our best to assist you by pointing you to the right direction.The recommended way is to create an executable (.exe) for each STK modem. E.g. 8 STK modems will have 8 exe. This is easiest and safest. Threading requires programmer having good understanding of thread coding.
The “MobitekSTK6.dll” is apartment threaded. Refer to http://danadler.com/jacob/JacobThreading.html
“If you are using a component that declares itself as ThreadingModel “Apartment” (you can find this out by looking in the registry under its CLSID), and you plan to create, use and destroy this component in one thread – then you are following the rules of an STA and you can declare the thread as an STA thread.”We suggest that you code according to single threaded apartment (STA) instead of multi-threaded apartment (MTA). This means:-

  • all threads must be independent of other each other
  • thread 1 cannot call or pass values to thread 2

Please refer to
ScriptTest.java – creates an STA for the ScriptControl component and runs all its method calls from that STA.”

What is the Maximum Number of USB Ports in Windows?

The maximum number of USB ports can be created in Windows is 256 ports (in theory).

But reality is 127 ports, so about 31 units of MOBITEK Q24 STK Modem Hubs. So 124 SIM cards per server.

But 1 server has maximum of built-in 6 USB ports, so 6 Hubs x 4 = 24 SIM cards per server.

We suggest that you use MOBITEK Q24 STK Modem Hub, model: STKMH-EP432-C which is based on LAN connectivity to overcome USB port restriction on a server.
