FiPy on Telia Norway LTE-M1
Hello, Norway based Telia employee here!
I just got the GPy and FiPy in the mail today and I am trying to connect to a base station which is M1-enabled for testing purposes. I copied the example from the documentation but it does not seem to work. lte.isconnected() returns False no matter what I try? I saw that LTE.init() takes a cid parameter, should it be set to 1 for all operators except Verizon (that's how I read the documentation)?
There are some posts about a debug mode where I can see some more information and perhaps AT-commands. How do I enable this?
There are also some posts about the module needing to be certified with different operators. This has not been a problem for any of the others that I have tried (Ublox, Telit, Quectel, Simcom) and after asking around no one seems to know about us requiring any certification to allow devices in our network.
@GeirFrimann hello, I`m just starting out, can you share your settings for telia?
Well I'm living in Sweden, and after updating the modem firmware with the
latest file (upgdiff_33080-to-41065.dup) I finally got the device connected:
from network import LTE lte = LTE() def connect_internet(): MyApn = "lpwa.telia.iot" lte = LTE() lte.init() lte.attach(apn=MyApn) time.sleep(1) print("LTE coverage:", lte.ue_coverage()) while not lte.isattached(): time.sleep(0.5) print('Attaching...') lte.connect() while not lte.isconnected(): time.sleep(0.5) print('Connecting...') print("\nConnected to LTE-M:",MyApn) #--------------------------------------------------------- # MAIN #--------------------------------------------------------- connect_internet() client = connect_MQTT_Broker()
Connecting to COM3... LTE coverage: False Attaching... Attaching... Connected to LTE-M: lpwa.telia.iot Connected to MQTT Broker: mymqttbroker.com
I wish there where a easier way to upgrade the modem firmware though...

I'm not at Pycom anymore, the last manual I had access is the one published for Cat M1. Maybe one of the current team can help, sorry.
@jmarcelino I found on docs but the manual seems to not be NbIot https://docs.pycom.io/.gitbook/assets/monarch_4g-ez_lr5110_atcommands_referencemanual_rev3_noconfidential-1.pdf
@jmarcelino Where we can find the Seaquans manual for AT commands? Above link from xykon is not working anymore .
Hi! Today I finally got a breakthrough and managed to get the FiPy online on NB-IoT! Pycom are still working on LTE-M, but at least we are one step further!
This is what needs to be done:
- Upgrade Pycom firmware to at least version 1.18.1.r2 using the Pycom firmware update tool. At the time of writing, this version is only available through manual download via the forum: [LINK NO LONGER AVAILABLE]. Because of this, you can not use the automatic download in the updater tool but need to download the firmware and select "Upgrade from file".
- Upgrade Sequans firmware to at least version NB1–38729. This is the LTE modem inside the Pycom module. Note that only NB-IoT is working at the moment, Pycom are still working on LTE-M. Follow the steps here: https://docs.pycom.io/tutorials-and-examples/lte/firmware
- Below is an example sending and receiving data from an echo server, in this case echo.ublox.com:
from network import LTE import socket lte = LTE() lte.send_at_cmd('AT+CFUN=0') lte.send_at_cmd('AT!="clearscanconfig"') lte.send_at_cmd('AT!="addscanfreq band=20 dl-earfcn=6252"') lte.send_at_cmd('AT!="zsp0:npc 1"') lte.send_at_cmd('AT+CGDCONT=1,"IP","lpwa.telia.iot"') lte.send_at_cmd('AT+CFUN=1') print("Attaching...") while not lte.isattached(): pass print("Connecting...") lte.connect() while not lte.isconnected(): pass print("Creating socket...") s = socket.socket() address = '22.214.171.124' # echo.ublox.com port = 7 try: s.connect((address, port)) except OSError: print("Failed to open socket!") exit(0) print("Sending message...") s.send(b"Hello world\r\n") print("Getting response:") print(s.readline()) print(s.readline()) print("Closing socket and disconnecting...") s.close() lte.disconnect() lte.dettach() print("Test complete!")```

Thanks for your interest. I've reached out by e-mail because we need to collect some details regarding your network as you're running a test setup - we have no information on what Telia Norway is using for Cat M1.
