Fcm send out data

Hi,
I’m developing for Q2406B 6.52 firmware 3.04 open AT version.
I’d like to use timer too send out block of data(byte) trough UART1, and receive respons ( query and response task).
From ADL User Guide, I know that I must setup FCM to Data state.
Using Terminal emulator to view data communication, I can see sent data in Data window, while any AT command and response showed on At1 window.
When i tried to run in target mode, I didn’t get any data sent out from modem.
Modem respons to any listed at command, but I doesn’t sent out data/query I want.

I also get ADL_RET_ERR_PARAM when execute this function

adl_fcmSwitchV24State(handle_uart1,ADL_FCM_V24_STATE_DATA);

None of any dstributor in Indonesia would provide any solution for problems.
They could sell many unit, but provide no technical support.
Help for any solution .
Best Regards.
