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 (example-ublox-cellular-interface - Example program that uses the mbed UbloxATCellula… | Mbed) 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
Error Message: CMSIS-RTOS error: Stack overflow
Location: 0xAFF1
Error Value: 0x1
Current Thread: application_unnamed_thread Id: 0x10000F94 Entry: 0xD0B1 StackSize: 0x7D0 StackMem: 0x10003D48 SP: 0x10007F14

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

Hoping in Your help
