FiPY can't attach/connect to LTE (T-mobile, Europe)

[Antonio Gauta]

Hi, I'm having trouble making the LTE connection work.

It starts with:

Goes to

+--------------------------+--------------------+
| RRC TOP FSM              |SCANNING            |

Then to

    |            FSM           |        STATE       |

    | HP CAT FSM               |IDLE                |
    +--------------------------+--------------------+

And afterwards it loops back to the beggining and does everything again.

These are my band and apn settings

lte.attach(band=20, apn="internet.ht.hr")

Does anyone have any idea what is happening?
