Inquiries regarding iPhone STK

Inquiries regarding iPhone STK

Hello All,

There are few issue encounter for using iPhone STK, I will list out the potential issue found along using the STK:

1) STK command “Get Input” instructions
While “Get Input” command being instructed in a very short period of time (Approximately in less than 1s), iPhone will automatically reply to the “Terminal Response” and “Terminal Response” value will be 0X12- No Response from User.
This “Get Response” timer is way too short. Possible to take a look and modify the commands?

2) STK command sends DTMF Instruction While power on the iPhone; it can only send successful 4 times DTMF command, the fifth and subsequent DTMF command will be unsuccessful. iPhone require manually power on/off again in order to send 4 times DTMF command in this cycle.
Require kind assistant to take a look on this issue.

3) STK command in the setup call instruction
While power on the iPhone, “Setup Call” instruction able to execute within 11 times. Subsequence the 12^th time “Setup Call” execution will be failed and unsuccessful.
Proceed with Power on/off cycle will be having the same successful 11^th Setup Call and the unsuccessful 12^th attempts on the Setup Call.

Highly appreciated that Apple Program Engineers or expertise able to take a look in to this matter in Singapore.

Thanks

Best Regards,
