no can connect to vodafone spain NB-IOT with FIPY

hi mates!!:
i have a Fipy. i put a last stable firmware and update to last modem firmware.
>>> os.uname() (sysname='FiPy', nodename='FiPy', release='1.18.1.r4', version='v1.8.6-849-dfa1176 on 2018-11-12', machine='FiPy with ESP32', lorawan='1.0.2', sigfox='1.0.1') >>>and version for modem:
>>> FiPy with firmware version 1.18.1.r4 Your modem is in application mode. Here is the current version: UE6.0.0.0 LR6.0.0.0-40343i use a examples to try connect to vodafone, but not attached...
import sys import pycom import time import socket import ssl from network import LTE #colors off = 0x000000 red = 0xff0000 green = 0x00ff00 blue = 0x0000ff yellow = 0xffff00 # pycom.heartbeat(False) # pycom.rgbled(0xff0000) time.sleep(1) pycom.rgbled(0x00ff00) time.sleep(1) pycom.rgbled(0x0000ff) time.sleep(1) # lte = LTE() #set the apn lte.send_at_cmd('AT+CFUN=0') lte.send_at_cmd('AT!="clearscanconfig"') lte.send_at_cmd('AT!="addscanfreq band=20 dl-earfcn=6300"') lte.send_at_cmd('AT!="zsp0:npc 1"') lte.send_at_cmd('AT+CGDCONT=1,"IP","nb.inetd.gdsp"') lte.send_at_cmd('AT+CFUN=1') # lte.attach(band=20, apn="nb.inetd.gdsp") # while not lte.isattached(): pycom.rgbled(red) time.sleep(0.25) pycom.rgbled(off) print ( " NOT ATTACHED" ) # lte.connect() # start a data session and obtain an IP address while not lte.isconnected(): pycom.rgbled(yellow) time.sleep(0.50) pycom.rgbled(off) print ( "NOT CONNECTED")this is result:
NOT ATTACHED NOT ATTACHED NOT ATTACHED NOT ATTACHED NOT ATTACHED NOT ATTACHED NOT ATTACHED NOT ATTACHEDi try with example in documentation of pycom but not connect [ really no attach]
i have a few question:
- is possible create a tutorial for get a connection...
- exist a app for android to check a NB-IOT cover? (and test if really exist)
3)i'm confused because are a lot of topics with this problems but i think one topic (in tutorial mode) is for a easy paht for use a fipy....
i hope learn to used NB-IOT and fipy...
thanks

@robert-hh said in no can connect to vodafone spain NB-IOT with FIPY:
The second number is the bit error rate (ber), whic is not know beforehand. So it means now the device detects is a proper signal.
then. then, now I understand that it had a good signal, but the fipy was trying to attach herself all night, and she did not succeed.
it's just waiting, or we should give it the command to attach repeatedly ...
On the other hand, I'll check the commands you indicate

Btw do you have any experience with eDRX/PSM?
Sorry no. I'm restarting on that area now that I got the FiPy modules back from RMA.

@robert-hh
That's impressive. Btw do you have any experience with eDRX/PSM? I did not play with those features yet.

@danielm Not at a place where I have access to. using the help command, i compiled a list. It's not from the most recent version of the firmware:

@lafumat You can also probe the attach-status with the command
AT+CEREG?
That's what the micropython firmware does. If it returns a longer string than
+CEREG: 2,2
something like
+CEREG: 2,5,"E2AE","018C7A0C",9
then the device is attached.
-
@robert-hh
Are proprietary commands documented somewhere?
-
exist other command for view band is "on"?
There are a lot of proprietary commands (~400), which all start with AT!="command>". You could try:
lte.send_at_cmd('AT!="RRC:setDbgPerm full"') lte.send_at_cmd('AT!="RRC:showDetectedCell"')The first command enables debug commands.
You may have to repeat the second command .There is also:
lte.send_at_command('AT!="help"')
lte.send_at_command('AT!="help commansd_name"')
-
@lafumat The first number is the rssi value. And 26 is ecellent. The second number is the bit error rate (ber), whic is not know beforehand. So it means now the device detects is a proper signal.
-
i get more values:
27,99
31,99
26,99
32,99
always i get firts (26-32), but second parameter is always 99 (no signal)
-
@lafumat said in no can connect to vodafone spain NB-IOT with FIPY:
@robert-hh i change to:

but, is possible get 26 (excellent) and 99 not detectable?
exist other command for view band is "on"?
you are help full, i'm learn good :)

-
@lafumat Are you sure it is band 20? You could also try Band 8 or Band 3, although the latter is unlikely, being at a higher frequency. Please check also, that the antenna is properly attached.
-
@lafumat See also: https://www.gsma.com/iot/deployment-map/#ES
I could not find ad hoc, which band is used by Vodafoen Spain
-
@lafumat 99,99 means: not known of not detectable.
If the first number is in a range of 0..31, it indicates a signal strength, but everything below 10 is bad. See for instance http://m2msupport.net/m2msupport/atcsq-signal-quality/
-
@robert-hh said in no can connect to vodafone spain NB-IOT with FIPY:
AT + CSQ
i use direly in console:
>>> from network import LTE >>> lte = LTE() >>> lte.attach(band=20, apn="nb.inetd.gdsp") >>> lte.isattached() False >>> lte.send_at_cmd('AT+CSQ') '\r\n+CSQ: 99,99\r\n\r\nOK\r\n' >>>99,99 is a 100% signal?
if true, attchad returns false
-
@lafumat You could try AT+CSQ, which tells you the strength of the signal. That will give results even if the devis is not attached.
-
@robert-hh I have come to try it for more than 30 minutes.
I also do not understand that it takes longer the first time than others.perhaps, to make it easier you could consider a command to scan to check that coverage first exists (I do not know if that command exists), for later once we are sure there is coverage try to attach and then connect.
for that reason I also ask if there is any mobile application to read if there is coverage.
in principle the technicians of vodafone tell me where I carry out the tests if the coverage exists, but I imagine that it is relative ....
Thank you
-
@lafumat How long did you wait for attaching? The first attach attempot can take very long, like 15 minuts. After that, attaching is faster.
-
i probe this too:
from network import LTE lte = LTE() lte.attach(band=20, apn="nb.inetd.gdsp") while not lte.isattached(): time.sleep(0.25) lte.connect() # start a data session and obtain an IP address while not lte.isconnected(): time.sleep(0.25)but not attached, always returns FALSE
