We ran into an issue where the LX60/LX40 modem would only respond to incoming traffic while the Ethernet port was in use. We are connecting with CAT M1 with a Verizon SIM card with a generic firmware version. Other people have said that it was a service provider issue with the way the card was activated, but we found that to be untrue. The modem was going into sleep mode after it wasn’t seeing any connection to the Ethernet port. There isn’t a fix in a dropdown menu on the modem itself, you need to log in through telenet. I will attach the instructions on how to fix it directly from Sierra tech support. It took us a lot of man hours playing with the settings to get to here, so I hope we can help out someone with the same issue that we were having and not have to do the trial and error method. One other bug we found is that in ALEOS 4.12.0, under general, cellular we could see if we were truly connected to CAT M1 because it would only say LTE.
In ALEOS 4.11.1, you can go to the same place and if you were connected to CAT M1 it would have an additional line saying CAT M1. This is an issue in the latest ALEOS 4.12.0 that no longer has this line saying CAT M1. We contacted Verizon to see if we truly were using an activated CAT M1 SIM and they insisted it was, but we couldn’t see it. We re-installed 4.11.1 trying to fix our first issue with the modem not communicating without Ethernet connected and found the line in the cellular tab was there saying it was on the CAT M1 network. Hopefully this gets addressed in the next ALEOS update.

LX60 Problem 12/2019
our engineering team have looked at this and believe that the issue is related to a radio module sleep mode setting that causes the module to miss incoming requests when idle. In order to fix this, can you try the following procedure which will disable this mode:
From the ACEmanager > Services tab > AT (Telnet/SSH): check that telnet is enabled and which port is in use (default 2332).
From a cmd prompt on a Windows machine connected to the modem LAN, telnet to the modem (default would be: telnet 192.168.13.31 2332)
Sign in with user “user” and password same as for the ACEmanager.
You should see the response “OK”, but to confirm, type “ATI” and hit enter. You should see the response “LX60” and “OK”.
Enter the command:
atsendtorm?at+cedrxs?
7. You should get a response similar to the following (it may differ somewhat):
8. at+cedrxs?
9. +CEDRXS: 4,“1101”
10. +CEDRXS: 5,“1101”
11. OK
12. Enter the command:
13. atsendtorm?at+cedrxs=0
14. Response:
15. at+cedrxs=0
16. OK
17. Finally, check that the change was successful:
18. at*sendtorm?at+cedrxs?
19. Response:
at+cedrxs?
+CEDRXS: 4,“1101” We actually saw 0001**
OK
You can now close the telnet session (Ctrl Break or just close the window).
NOTE:
at*sendtorm?at+cedrxs=0 command was executed alright (ie, received an OK response), then the sleep mode should have been successfully disabled
Hi,
we’ve having similar issues, but on our LX60 we can not get use that AT commands.
They are not recognized.
maybe in EU version they are not present ?
It seems that his LX60 in original post has Radio Module Type named WP7702. So eDRX is enabled by default and he can use AT command to disable eDRXS mode.
You can check your Radio Module Type in ACEmanager → Status → About. If your Radio Module Type is not WP7702, I don’t think you are able to follow his procedure .
Could you try to update your radio firmware to the latest one and try again?
If you’ve connected to the router you can check that our radio firrmware is WP7607 (not WP7702).
Is this model affected by eEDRXs ? Does it have At commands for this, can you tell which commands to check ?
We already have upadted the last firmware and LX60 is not responding immedtiately with Vodafone, it waits (sleeping ?) and then is reachable after a few seconds, every time we check.
How can we solve this and disable sleep mode is this is the issue ?
If we can not solve we have to bring back all to our reseller.
We’re using a custom APN, but after upgrading firmware on one LX60 it loose the custom APN and reset to the standard APN for that operator, and that APn does not work in bidirectional mode.
How can we be sure that APN is not lost after firmware upgrading (we do upgrade to remote devices) ?
I have taken a look on your configuration file and have some points:
You should set ACEmanager->Service->Power Management->Low Voltage Standby Mode to “Automatic” mode if you don’t play around with it.
Your ALEOS software version is 4.11.1 and radio FW version is 02.16.02. Is it a right template file?
In case this problem cannot be resolved, returning your LX60 and reporting this issue to reseller is the best ideal.
For your another question about APN, I think you should create a new topic in order to make it easier for members in this forum to search for a solution.
As I know, Sierra recommends that all configuration should be set as default if user don’t have specific purpose.
I have checked your configuration file and there is no difference from the old one. The possible thing you can do now is to reset your device to factory default and check this issue again.
To reset your device to factory default, press Reset button for 7-20 seconds and release it when the power LED flashes red. If your want to go back to your old settings, go to ACEmanager → Template → Upload your configuration file.
