RAK3400 interface with Ublox

I am using RAK3400 in Segger Embedded Studio for interfacing Ublox-max7Q.
I have tried to replicate the Arduino TinyGPS library but the ublox GPS module doesn’t give any response.
Have any one used ublox-7q. please do reply.

Thanks in Advance.

Sorry, but what is a RAK3400?
I am not aware of that module. Must be something older, it is neither in our Store nor in our documentation center.
