Troubleshoot SWWAN "SM activation error",136 on ELS61-E | Telit Cinterion IoT Developer Community
August 29, 2023 - 7:35am, 133 views
Hello, I have a ELS61 based routed and I managed to use it on MBIM mode. However, I would want to try it on ECM with AT^SWWAN=1,2 but it returns a +CEER: "SM activation error",136,"Regular PDP context deactivation" error. However, I am able to ping with AT^SISX="Ping"

I would appreciate any suggestion to figure out what's wrong with my setup.

Hello,
Please share more information how you do that, with what environment etc. For instance did you use the same APN and context for MBIM, did you sent ECM with AT^SSRVSET and rebooted etc.

Hello,
If I understood correctly what you mean by environment, I am currently running on a test bench indoors.
And yes, I use the same "orangeworld" APN for both configurations, actSrvSet was on 1 but I set it again AT^SSRVSET="actSrvSet",1 and I rebooted with at+cfun=1,1. After the reboot, I do a check with AT+CEREG? and AT+COPS? and, finally, the AT^SWWAN=1,3.

By environment I meant the OS and how you exactly proceed with the connection setup. After bringing up WWAN interface you need DHCP client in your OS to get the IP address. Please see also here https://iot-developer.thalesgroup.com/knowledge-base?title=wwan&field_kb...
I was following How to Guide: ELS61/PLS62 and Linux Startup | Telit Cinterion IoT Developer Community (thalesgroup.com) which assumes that NetworkManager would enable the connection. However, for me it does not but I managed to get it running launching the dhclient myself.
Is there a way to achieve the same under a Windows OS on ECM mode? I get an 169.254.X.X IP on the adapter so the AT^swwan fails.
Thank you BARTŁOMIEJ
