Ublox C027 bug cellular interface

Hi all!
I’m working on a simple hello ublox cellular interface example. I’m using the code of the example ( with just some minor customization:

I’ve putted the example code inside a Thread (I need this for my project); everything works fine if I use mbed online compiler, BUT, using an offline IDE (I use GCC_ARM Toolchain and target UBLOX_C027 to compile) Errors comes up:

++ MbedOS Error Info ++
Error Status: 0x80020125 Code: 293 Module: 2

How can I fix this? I’ve already tried to manually set memory reserved for the thread and thread priority with no benefits…
