I've got several of these boards and they've worked okay for me without doing anything special. I have not tried the software you are using, however, nor do I use the adapter you mention (does that adapt the connector on the SSR-6tru to a connector that fits your UT+ board?). I made a connector to talk to mine directly from a 3 volt serial port in a BBB SOIC. Since you can see the NMEA sentences the transmit side of the serial port from the LEA-6T is clearly working and you have the baud rate right, but your symptoms suggest the module doesn't hear you. Have you tried looking at the basic connection, i.e. that the serial port receive pin on the module wiggles at the right voltage and polarity when the software tries to send stuff (maybe there are two ways to plug in the adapter, only one of which works)? If that looks okay then the only other guess I can think of is that the software is trying to talk to the board with u-Blox binary messages but that protocol has been turned off for input on the port (the PUBX,41 NMEA sentence can turn it on and off), but that seems unlikely since, no matter how I reconfigure mine, a power-on reset always sees the serial port come up willing to receive either protocol.
