Need Help to connect NB-IOT 1nce / Germany

[svonbentzel]

Hello togehther, I need help.

I have multiple FiPy Boards with and without expansion board try´d.

I have used two 1nce SIM-Cards. The cards working good. and its a NB-IOT Contract.
FiPy Rev. 1.2 RMA from Pycom
Modem Firmware is already updated to DUP NB1-41019
LTE-Antenna is connected
SIM-Card is correctly plugged in.

i have try multiple NB-IOT connection Scripts. no ones run.
i have running the script multiple hours inside and outside of the House.

any Ideas and Hints?

@svonbentzel Did you setup the AP?
Something like 'AT+CGDCONT=1,"IP","internet.nbiot.telekom.de"' ?

[svonbentzel]

@Elizar Hello, Yes I think ;)

from network import LTE
import time

lte = LTE()
lte.attach(band=8, apn="iot.1nce.net")
while not lte.isattached():
    time.sleep(0.5)
    print(".", end="")

print("\nAttached!")

print(lte.send_at_cmd("AT+CSQ"))

lte.connect()       # start a data session and obtain an IP address
while not lte.isconnected():
    time.sleep(0.5)
    print("-", end="")

print("Connected!")

Second Script:

import os
from network import LTE
import usocket
import time


def send_at_cmd_pretty(cmd, delay=1000):
    response = lte.send_at_cmd(cmd, delay=delay).split('\r\n')
    print('Sent to modem: \'{}\', delay {} ms'.format(cmd, delay))
    for line in response:
        if line.strip() != '':
            print(line)


# Print module details
un = os.uname()
print('Sysname:', un.sysname)
print('Release:', un.release)
print('Version:', un.version)
print('Machine:', un.machine)

# Initialize LTE object
lte = LTE()
time.sleep(5)

# Pre attaching debugging
print('Query LTE modem imei...', lte.imei()[:5] + '*' * 10)
print('Query SIM iccid...', lte.iccid()[:5] + '*' * 15)
send_at_cmd_pretty('ATI1')
send_at_cmd_pretty('AT!="showver"')
send_at_cmd_pretty('AT!="RRC:setDbgPerm full"')
send_at_cmd_pretty('AT!="RRC:showcaps"')
time.sleep(5)
send_at_cmd_pretty('AT+SQNCTM?')

# Attach LTE
print('LTE attaching...')
lte.attach(band=8, apn="iot.1nce.net")
attempts = 0
while not lte.isattached():
    time.sleep(5)
    attempts = attempts + 1
    print('Attaching...', attempts)
    if attempts % 15 == 0:
        send_at_cmd_pretty('AT+SQNMONI=9')
        send_at_cmd_pretty('AT+CEREG?')
        send_at_cmd_pretty('AT+CFUN?')
        send_at_cmd_pretty('AT+CSQ')
        send_at_cmd_pretty('AT!="showphy"')
        send_at_cmd_pretty('AT!="fsm"')
print('LTE attach succeeded!')

# Debug attached state
send_at_cmd_pretty('AT+CEREG?')
send_at_cmd_pretty('AT+SQNMONI=9')
send_at_cmd_pretty('AT+CSQ')
send_at_cmd_pretty('AT!="showphy"')
send_at_cmd_pretty('AT!="fsm"')
send_at_cmd_pretty('AT+CGPADDR')
send_at_cmd_pretty('AT+PING="8.8.8.8"', delay=5000)

# Connect LTE
lte.connect()
attempts = 0
while not lte.isconnected():
    time.sleep(5)
    attempts = attempts + 1
    print('Connecting...', attempts)
print('LTE connection succeeded!')

# Test DNS
try:
    usocket.dnsserver(0, '8.8.8.8')
    usocket.dnsserver(1, '1.1.1.1')
    usocket.dnsserver()
    print(usocket.getaddrinfo('www.google.com', 80)[0][-1])
except Exception:
    print('DNS over NB-IoT failed...')



# Shutdown LTE
print("Disonnecting LTE ... ")
lte.disconnect()
print("Detaching LTE ... ")
lte.dettach()
print("Shuttting down LTE...")
lte.deinit()

@svonbentzel The first script is the one I uss too for testing and it works. Only I have a different firmware version:
Pycom MicroPython 1.20.0.rc10 [3911a85-dirty] on 2019-04-17; FiPy with ESP32
Edit: updated to:
Pycom MicroPython 1.20.0.rc11 [55accd1-dirty] on 2019-05-24; FiPy with ESP32, same good state.
