Help wanted NB-iot issue

[AM]

I am test Fipy with nb-iot and running the Coap example code from Telenor CoAP code. Everytime I try to run the code I get this error.

Initializing filesystem as FatFS!
Traceback (most recent call last):
  File "main.py", line 1, in <module>
  File "/flash/lib/telenor.py", line 3, in <module>
ImportError: cannot import name Coap
Pycom MicroPython 1.20.0.rc13 [v1.9.4-94bb382] on 2019-08-22; FiPy with ESP32

I tried with CATM1 same error.

(sysname='FiPy', nodename='FiPy', release='1.20.0.rc13', version='v1.9.4-94bb382 on 2019-08-22', machine='FiPy with ESP32', lorawan='1.0.2', sigfox='1.0.1')

Welcome to the SQN3330 firmware updater [1.2.6] >>>
>>> FiPy with firmware version 1.20.0.rc13

lte.isattached() alwats give false even when I try to REPL

from network import LTE
lte = LTE()
lte.deinit()
lte.init()
lte.attach(apn="telenor.iot", band=20)

Any Ideas on how to fix this problem.
