Description of Problem:
We are able to start multiple threads, but we are now getting this error;
#
# A fatal error has been detected by the Java Runtime Environment:

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
  • 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.

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

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.”

Which programming language are you using?
  • JAVA
  • JRE version: 8
  • JACOB versio: 1.14.3
OS Windows 7,  64 bit
Description of Problem: Three of the modems on one of the STK Hubs we ordered are not working. I have attached logs with the request.


Analysis
Based on the “STKEngine.log.txt”,the modem is able to initialise successfully using Modem.Init() is at COM port no. 18 (and not 17)

    • 2015-10-08 10:48:43 INFO  StkProcessor:117 - GSM modem port: 18 is connected to computer.
      2015-10-08 10:48:43 INFO  StkProcessor:128 - GSM modem port: 18 is connected to GSM network.
      2015-10-08 10:48:44 INFO  StkProcessor:131 - The operator of the GSM network is VodaCom Tanzania. Port: 18

Follow these steps and answer all questions:-

  1. What is the OS that Ports: 17,18,19,20 is having problem?
    Answer: Win 7  64 bit
  2. Does COM port no. 17, 19 and 20 has exclamation mark in “device manager”, refer image below and attached manual (same copy is in the CD)
    • Screenshot_1
    • Screenshot_2
    • Answer:  No
  3. If “yes”, kindly re-install the driver (by uninstalling and then re-install again)
  4. If “no”, then unplug STK MODEM HUB (Ports: 17,18,19,20) from server, and plug into another PC/server
    • IMPORTANT: make sure you select the correct driver version for the OS
    • install the USB driver, make sure there are no exclamation marks
    • make sure that only 1 hub is connected to the server/PC (we want to avoid conflicts/inteference)
    • the COM ports will be different, please check in device manager
  5. Run your Java code, does it work?
    Answer:  No
TROUBLE SHOOTING STEP no. 1: Please follow and answer all questions:-

  1. Connect the faulty hub (reported as  FAULTY HUB. Ports: 17,18,19,20) to another server.
  2. Ensure that MOBITK STK API version 6.4 is installed on another server.
  3. Ensure only 1 hub is connected to this server. There are no other hubs/modems.
  4. Install the correct USB driver. 4 Com ports will be generated.
  5. Ensure your Java programme is NOT running.
  6. Download a zip file:-
    • web browser will prompt for login, enter:
        • username = all
        • password = wemakesystemstalk
  7. Unzip “Testing Connection with MOBITEK Q24 STK Modem Hub.zip” onto your desktop

    • Answe: No
  9. Exit SIM Tool Kit.exe. Turn on power to modem “M2” only. Power to other modems are off. Run our SIM Tool Kit.exe (VB.Net executable), specifiy the COM port for “M2”. Click on the button “Connect to STK Modem”. Connected?
    • Answe: Yes
  10. Exit SIM Tool Kit.exe. urn on power to modem “M3” only. Power to other modems are off. Run our SIM Tool Kit.exe (VB.Net executable), specifiy the COM port for “M3”. Click on the button “Connect to STK Modem”. Connected?
    • Answe:    No
  11. Exit SIM Tool Kit.exe. Turn on power to modem “M4” only. Power to other modems are off. Run our SIM Tool Kit.exe (VB.Net executable), specifiy the COM port for “M4”. Click on the button “Connect to STK Modem”. Connected?
    • Answe:  No
  12. If “no”, then attach log file, “MOBITEK STK API Log ….txt".
  13. Attach screen capture of error message if any.
TROUBLE SHOOTING STEP no. 2:
  1. shut down power to STK MODEM Hub and disconnect the power cable to the Hub
  2. open the top panel
    • Screenshot_3
  3. check the cable connection between modem and PCB
    • ensure both ends are tightly connectedScreenshot_4
  4. Repeat the Trouble Shooting Steps no. 1 as mentioned above and give us the result:-
    • Turn on power to modem “M1” only. Power to other modems are off. Run our SIM Tool Kit.exe (VB.Net executable), specifiy the COM port for “M1”. Click on the button “Connect to STK Modem”. Connected?
      • Answer: Yes   /   No
    • Exit SIM Tool Kit.exe. Turn on power to modem “M2” only. Power to other modems are off. Run our SIM Tool Kit.exe (VB.Net executable), specifiy the COM port for “M2”. Click on the button “Connect to STK Modem”. Connected?
      • Answer: Yes   /   No
    • TExit SIM Tool Kit.exe. urn on power to modem “M3” only. Power to other modems are off. Run our SIM Tool Kit.exe (VB.Net executable), specifiy the COM port for “M3”. Click on the button “Connect to STK Modem”. Connected?
      • Answer: Yes   /   No
    • Exit SIM Tool Kit.exe. Turn on power to modem “M4” only. Power to other modems are off. Run our SIM Tool Kit.exe (VB.Net executable), specifiy the COM port for “M4”. Click on the button “Connect to STK Modem”. Connected?
      • Answer: Yes   /   No

If the result remains “No”, then we will proceed to claim warranty.

Final Solution: We manage to check the device after opening the case, and realized the cables where disconnected. Now we have all modems working and connected.
