Connect Android with PAN1740 usb stick by SPS dialog example

Hi to all.
I'm try to connect SPS application on PAN1740 usb dongle to Android PDA but it seems not to work.
1) I download DA14580 SDS application by Dialog website.
2)编辑da14580_config.h:
#undef CFG_UART_HW_FLOW_CTRL
#define CFG_UART_SW_FLOW_CTRL
.
.
.
#undef CFG_EXT_SLEEP
#undef CFG_DEEP_SLEEP
3) install DSPS app on Android PDA
4) Compile SPS project with uVision5
5) Boot as peripheral hex file with connection manager
6) Close connection manager
7) Open tera term connect to right port, edit settings port with 115200bps 8bit no parity 1stop Xor/Xoff
8) On DSPS I see DA1458x device but in/out transimission don't work.
What's wrong in this procedure?
