Hello,

I have issues with EHS6T Modems. I  use them  for USSD via AT Command  from LAN only. They Works fine for 1 day and then an "failed to set dtr/rts"  error occurred and I'm no more able to connect to Modem NOR run AT Commands until a hard reboot. OS reboot doesn't fix issue either. I disabled power saving Mode and disable PPP service.

Attached is the system Log with full errors.

Please need a help to fix issue as I'm using them for Enterprise Service in production.

 

Regards.

Hello,

Thanks for your help. I will enable SSH on all others and then get Logs while the errors occurs and share with you.

But I have new error today when trying to access GUI:

 

/usr/lib/lua/luci/dispatcher.lua:533: bad argument #1 to 'pairs' (table expected, got nil)
stack traceback:
	[C]: in function 'pairs'
	/usr/lib/lua/luci/dispatcher.lua:533: in function 'createtree'
	/usr/lib/lua/luci/dispatcher.lua:201: in function 'dispatch'
	/usr/lib/lua/luci/dispatcher.lua:168: in function </usr/lib/lua/luci/dispatcher.lua:167>

On this one I enabled SSH so I got Logs that I will share in new post.

The only thing I noticed Lan goes UP and Down sometimes...

Certainly this Firmware is not stable. Please, could you advise on  the most stable and suitable Firmware for this model of terminal ?

 

Thanks.

Hello,

I don't think it brings anything new unfortunately. 
So, first I would try to stop and restart ser2net to see if it can work again, I would check the module connection over RS232 to see if it's alive and fully functional. Or I would try to communicate with it on the other virtual USB from within the OpenWrt system and if the module replies on the interface previously used by ser2net. I would disable WAN connection if the only functionality you need is USSD.
Then I would also try newer FW image on one of the devices. But this is something that you can't withdraw. it is only possible to download the other image.
At the same time or after that I would report this to Thales support system or your local M2M contact person or distributor. If the problem is officially reported there may be more possibilities of supporting you.

Regards,
Bartłomiej
