Step by step guide on how to change COM Port number
Step 1: Open device manager, and expand ‘Ports (COM & LPT). I will use MobiGATE SG-B-8-U for this example
Step 2: Select the COM Port you want to change, right click and click on ‘Properties’
Step 3: Click on ‘Port Settings’ tab
Step 4: Click on ‘Advanced’
Step 5: Select the COM Port that is not in use. I will select COM Port 26 for this example.
Step 6: Click on ‘OK’. The COM Port is changed now.
Version 4.5 supports 8 STK Engines. The setup.exe will create 8 MOBITEK STK ENGINES (previously was 4 STK Engines) in order to support the new MOBITEK Q24 STK MODEM HUB model: B-8-U

Contains installer for MOBITEK STK API version 6.5.
PROBLEM: the STK ENGINE has problem submitting “OK” to STK. Refer below for the log in “ini” file:
Confirm reload to 0173737692 with RM 10.00 now > OK STK status is unknown. > STK status is unknown. STK status is unknown. STK status is unknown. STK status is unknown. STK is deactivated! 12/21/2015 4:25:58 AM
SOLUTION: bug fixed in MOBITEK STK ENGINE version 4.4

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:-

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.
M-Pesa
There are new batch of M-Pesa SIM Card with STK (SIM Tool Kit) that requires you to input value in UCS2 format instead of text format.
In order to submit or input value in UCS2 using MOBITEK® Q24 STK API , you need convert the text into USC2 (hexadecimal) format, e.g.
Michael => 004d00690063006800610065006c
STK refers to SIM Tookit or SIM Tool Kit.
SAT refers to SIM Application Toolkit
Both terms are interchangeable.
