FiPy, NB-IoT, 1nce/ Telekom.de germany: fails, no band 8 support?
-
I have a FiPy with a 1nce sim installed.
>>> from network import LTE >>> lte = LTE() >>> lte.attach(band=8, apn="iot.1nce.net") Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: band 8 not supported >>>Err? is that correct? No band 8 would mean that the combo of FiPy and 1nce (which is on the Deutsche Telekom LTE network/is a brand of Deutsche Telekom, see https://halberdbastion.com/intelligence/mobile-networks/telekom-deutschland) will never work.
-
@cts Pycom called back the Fipy devices to upgrade it so support all bands, including band 8.
Send a mail to RMA@pycom.io, explaining your need, and ask for instructions. The will send you a link to a RMA form. -

@cts Have you sent in your FiPy back and did you get it to work now?
I'm trying to work with GPy and 1NCE.
-
Just tried today to connect via 1nce with (updated) GPy Band 8 -> no attachment possible :( anyone got it working?
-
@dom With the November modem firmware NB1-40343 and a 1nce card my devices get connected. Band=8, EARFCN=3740, Python firmware 1.20.0.rc7.
The first attach took like forever, like 10 minutes, but then it was OK. It takes like 10 seconds after a colde boot to attach. Still way worse than a SIM7020 modem I have, which attaches in less than a second, after is had the initial attach once. -
Do I really have to send all my divices back to Pycom, if I like to use band 8? Robert are you living in Germany? Have you experience with the network coverage of (1nce) NB-iot? I will maybe buy some cards from Telefonica, because they also support roaming for the Vodafone and the Telekom network in addition to the Telefonica network.
-
@tvetter1976 From what I learned from the discussion, the device have to be returned to Pycom. Whether they are upgraded or replaced, I cannot tell.
And yes, I live in Germany, but never tried to use the device outside my home. That is still on my list. I could try to get information about the coverage. -
Hi, am also trying to get a 1nce SIM card running here in germany.
I tried the "normal" way as the pycom documentation suggests:from network import LTE lte = LTE() lte.attach(band=8, apn="iot.1nce.net")but even after 15 minutes i couldn't get any result.
I also tried to connect via AT commandslte.send_at_cmd('AT+CGDCONT=1,"IP","iot.1nce.net"') lte.send_at_cmd('AT+CFUN=1') lte.send_at_cmd('AT+COPS=1,2,"26201",9')and the "custom" commands like
lte.send_at_cmd("AT!=\"RRC::addscanfreq band=8 dl-earfcn=3740\"")So far neither of the approaches did work for me.
Could you please describe what exactly you did to get a working connection?Thanks a lot!

@bqpd That is a short script which works:
# 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!")The value returned by AT+CSQ is 25,99, which indicated a good reception. As antenna I use a quarter-wavelength 868 MHz antenna, which I tested to work well enough up to the LTE band 8 frequency. The Pycom Lora antenna should be fine too.
-
@robert-hh Thanks a lot! I will test it soon. Maybe i should also try it in a larger city to minimize the risk of net availability issues.

@robert-hh
today i was able to try this script. I updatetd the firmware to MicroPython 1.20.0.rc1 and the sequans firmware updatetd with "upgdiff_33080-to-40343.dup" on my GPy successfully.
I inserted the 1nce SIM and tried your script with connected pycom LTE-antenna via Atom shell in Munich.Unfortunately i wasnt able to attach... i tried several times, each for 45 min but nothing happend.
Any idea what can be wrong? What else i can try?
Thanks

@andy_n I do not recall if you have a FiPy module refurbished by PyCom for BAND=8 support. If not, the software may accept the setting, but it will simply not work. You can query the list of supported bands with:
from network import LTElte = LTE() lte.send_at_command('at!="RRC:showcaps"')It should return something like:
== CAPS config ============================= .Lock UE on SRV band : false .MFBI support : true .TM8 TDD support : false ============================================ == CAPS ==================================== . access stratum: R13 . catM : 1 . nb-IoT : 1 -- EUTRA bands -- . supported : 28/20/13/12/8/5/4/3 . board : 3/4/5/8/12/13/20/28 . admin : . pending admin : -- EUTRA carriers -- . admin : . pending admin : ============================================ OK -
@robert-hh Showcaps does not work for me.
>>> from network import LTE >>> lte = LTE() >>> lte.send_at_cmd('at!="RRC:showcaps"') '\r\nNo permission to use the RRC private debug CLI\r\n\r\nOK\r\n' >>>I also have the problem that I can't connect on band 8 on an upgraded GPy.
What other way is there to see if the firmware supports band 8?

Found solution for showcaps rejection from another thread.
>>> from network import LTE >>> lte = LTE() >>> print(lte.send_at_cmd('AT!="RRC:setDbgPerm full"')) OK >>> print(lte.send_at_cmd('at!="RRC:showcaps"')) == CAPS config ============================= .Lock UE on SRV band : false .MFBI support : true .TM8 TDD support : false ============================================ == CAPS ==================================== . access stratum: R13 . catM : 1 . nb-IoT : 1 -- EUTRA bands -- . supported : 28/20/13/12/4/3 . board : 3/4/12/13/20/28 . admin : . pending admin : -- EUTRA carriers -- . admin : . pending admin : ============================================ OK >>>So this means that this one needs to be RMA'ed?
-
@joop-susan Yes.

I am lucky to have:
>>> print(lte.send_at_cmd('at!="RRC:showcaps"')) == CAPS config ============================= .Lock UE on SRV band : false .MFBI support : true .TM8 TDD support : false ============================================ == CAPS ==================================== . access stratum: R13 . catM : 1 . nb-IoT : 1 -- EUTRA bands -- . supported : 28/20/13/12/8/5/4/3 . board : 3/4/5/8/12/13/20/28 . admin : . pending admin : -- EUTRA carriers -- . admin : . pending admin : ============================================```And I can confirm that it works without any SimCard inserted!

@joop-susan
here the same problem, but your code worked.>>> from network import LTE >>> lte = LTE() >>> print(lte.send_at_cmd('AT!="RRC:setDbgPerm full"')) OK >>> print(lte.send_at_cmd('at!="RRC:showcaps"')) Traceback (most recent call last): File "<stdin>", line 1 IndentationError: unexpected indent >>> print(lte.send_at_cmd('at!="RRC:showcaps"')) == CAPS config ============================= .Lock UE on SRV band : false .MFBI support : true .TM8 TDD support : false ============================================ == CAPS ==================================== . access stratum: R13 . catM : 1 . nb-IoT : 1 -- EUTRA bands -- . supported : 28/20/13/12/4/3 . board : 3/4/12/13/20/28 . admin : . pending admin : -- EUTRA carriers -- . admin : . pending admin : ============================================ OKok so there is no band 8 in the supported line...
i also need to send the boards back to geht upgraded ones...
Thanks a lot! -
@robert-hh
Can you give an example how to send data using 1nce sim card?
