Wed Mar 18, 2020 7:57 am

ROS 6.47beta35. LM940 modem. Routerboard RBLHGR.

Steps taken:
- Modem set to usb2.0
- Modem in LTE mode (and ROS reading it)
-Using same APNs in this modem as the last with the same sim card
-LTE is enabled

ISSUE:
-No internet
-LTE1 is "not running"
-Registration Status: searching

I have found these errors in the log:
Buffer lte
Topics lte
error Message SXTR_LTE: lte1 SMS storage set failed ( I do not have a SXTR_LTE. )

Topics lte async: Message SXTR_LTE: lte1: rcvd +CME ERROR: operation not supported
I don't know what else to check.

At start disable the GSM network, the LM940 not support that ! 3G and 4G only are support. ROS command:
/interface lte set lte1 network-mode=3g,lte
Maybe that ROS try enable GSM=2G who is not supported create you a problem.

At LM940 AT command manual I see that commands and Telit post (https://www.telit.com/technical-forum/o ... t-allowed/) who describe what to check:

Page 66, SIM/PIN status by
/interface lte at-chat lte1 input="AT+CPIN\?"

Page 55, Registration in network by
"enable network registration unsolicited result code"
/interface lte at-chat lte1 input="AT+CREG=1"
+CREG: <stat>
Where:
<stat>
0 - not registered, ME is not currently searching a new operator to register to
1 - registered, home network
2 - not registered, but ME is currently searching a new operator to register to
3 - registration denied
4 - unknown
5 - registered, roaming
Wait some time and repeat by
/interface lte at-chat lte1 input="AT+CREG\?"
+CREG: 0,2 (the MODULE is in network searching state)
+CREG: 0,1 (the MODULE is registered)
Page 198, Serving Cell Information, After registration try this:
/interface lte at-chat lte1 input="AT#SERVINFO"

Good Luck and give feedback, and LOGs in file

i have been facing the same issue. this is what helped me:
- remove the SIM card from Mikrotik device
- put the SIM card to some other device.
- delete all SMS messages on SIM card using the other device
- put the SIM card back to Mikrotik

seems to be some bug in MikrotikOS.
