Connection to NB-IOT issues. How to get logs

[robert-hh]

@Nab The first attach may take VERY LONG, longer than 15 seconds.
May I also ask for:

• the version of the ESP32 firmware (push Ctrl-B)
• the version of the Sequans modem firmware (get it with)

from network import LTE
lte=LTE()
print(lte.send_at_cmd('AT!="showver"'))

that you are using.
