Emnify using NB-IOT in UK

[cristianspiridon]

Hey guys,

I need help starting with gpy and NB-IOT. I have a simcard from EMnify they are NB-IOT capable, but I have problems running an example. the example bellow is not attaching.

import pycom
import time
from network import LTE

Disable Heartbeat

pycom.heartbeat(False)
pycom.rgbled(0x0)

lte = LTE()
lte.init()

lte.send_at_cmd('AT+CFUN=0') # disable modem
lte.send_at_cmd('AT!="clearscanconfig"') # clear scanned frequencies
lte.send_at_cmd('AT!="addscanfreq band=20 dl-earfcn=6300"') # set scanned frequency
lte.send_at_cmd('AT+CGDCONT=1,"IP","em"') # set APN (Access Point Name)
lte.send_at_cmd('AT+COPS=?') # scan available networks
lte.send_at_cmd('AT+CFUN=1') # enable modem

lte.attach()

print("attaching:", end="")
while not lte.isattached():
print("", end=".")
pass
​
print("connecting:")
lte.connect()
while not lte.isconnected():
print("", end=".")
pass
