Hello
I’m trying to work with MC7710 modem and RB411 (V6.5)
I can see I get in the interface
but what I need to config in it ?
this is what I get when I want to find info
/interface lte info 0
failure: Configuration running, please wait!
is someone know this modem and can help ?
Thanks ,
please upgrade the RouterOS to v6.10.
Disable the lte interface and then try to run the info command.
O.K.-still doesn’t work
this is what I have now-
version of the modem - SWI9200X_03.05.24.00ap r5792 carmd-en-10527 2013/05/02 13:35:47
when I press info I get this (I have antenna connected to Main connector)
I get functionality -“minimum”
also - it will only work when I’m on Auto\GSM - way is it?
it shows minimum because it isn’t enabled and connected to the network.
When the interface is enabled and connected to the network it will show full when you will do info command.
About the Auto mode I am not sure, check if your SIM card supports LTE operations and if it is enabled on the Mobile operator.
I will do this and let you know
Thank you for now
Well I talk to them and they say that the SIM I have is open to LTE
but still is doesn’t work - and even if I try to connect to GSM\3G
and doesn’t even show me he dial or something ??
I have “open” log topic=lte
and this is what I get :
15:55:08 lte,error internal init failed: +CME ERROR: no network service
help?
Thanks,
do I need to make the modem dial some how?
because I have check the modem with develop board - and it’s working and connect to 4G
what am I missing here?
I have config
User,Pass,APN ? is there anything else?
and this is what I get in the debug - no response???
after adding
at+cfun=1
I can see now it’s running , but we still won’t connect to the internet
why?
there is no need to specify that modem-init entry for this modem.
What firmware version are you using on the sierra card?
I got the modem with this version -
SWI9200X_03.00.02.00AP R2032 CARMD-EN-10526 2011/05/17 17:47:02
also I have try to use this versions
SWI9200X_03.05.23.02ap r5708 carmd-en-10527 2013/03/14 20:07:35
SWI9200X_03.05.24.00ap r5792 carmd-en-10527 2013/05/02 13:35:47
what else?
those are ok firmwares. Remove that modem-init entry and then check what you see in the logs.
still the same , this is the log
do you want to see something else ? another logs?
It is Running already - now you just need to add a dhcp-client on the lte1 interface.
ohhhh 
so this is all I had to do? just had DHCP client…
o.k. now I can see it’s working , Thanks !
is there a reason why the other version didn’t work for me?
and 1 more question
why I can’t use “info” while the LTE is working?
how can I know what is the signal? and where it is connect to ?
all I get is “modem did not respond”
?
when the connection is established and running the info command on the lte interface should be running.
Check the log file what is reports when you try to run the info command.
This is what I get in the log (debug+lte)
03:24:24 async,debug lte1: sent AT+COPS?
03:24:29 async,debug lte1: sent AT+COPS?
03:24:29 async,debug lte1: sent AT+GMI

03:25:14 async,debug lte1: sent AT+COPS?
from the logs it looks like the modem is locked up and not running and that is why the info doesn’t work.
You can try to do the usb power reset if the board supports.
2 questions now:
the modem is working and running - I have connection to the internet all the time.
how do I do usb power reset? I’m using RB411
I am not sure why it is not working. Also providing some special user command as welll?
I have such firmware and info is working ok:
SWI9200X_03.05.24.00ap r5792 carmd-en-10527 2013/05/02 13:35:47
RB411u board doesn’t have usb power reset
but you could try to reset the modem with AT command AT+CFUN=1,1
I didn’t use any special user command- (if you mean AT command)
this is how I got it ,no change were made.
something is weird now -
I have remove the modem and then put it in again
and it show me the info for 5-6 seconds , then i got “modem didn’t replay”
and again the info command isn’t working
I have done soft reset and hard reset - nothing
just when I remove it from the RB it’s working
and also - how can I use “AT Command”? I can’t reach the modem using Serial
when I do
/system serial-terminal usb2 channel=0
I get nothing - can’t write or anything
what could it be?
