connection lost after some days

[Markus Duschek]

hi

My configuration is:

Multitech Conduit (MTCDT-LEU1-247A) with loracard (MTAC-LORA-H-868) and GSM Cellular for WAN Transport.

After a few days of trouble-free operation, the gateway no longer sends data. after a restart, everyone is back.
I looked at the log files and found the following:

14:43:08 INFO: Watchdog is disabled
14:43:08 INFO: Contact email configured to “xxx.xxx.com”
14:43:08 INFO: Description configured to “Gateway from IBBD.AT”

14:43:13 *** Lora concentrator HAL library version info ***

devicehq is not interrupted. Only the last seen status on console.thethingsnetwork.org is interrupted and and packages are not received.

I was going to suggest the ttn forum as well, but you are already there!

The log has this message but the unit is working after reboot?

Take note of the IP address on PPP
$ ifconfig

When the device fails check again if the IP address has changed on the cellular interface.

Try to add “autoquit_threshold” to the gateway config to restart if the IP changes.

Check that there is only one packet forwarder process running
$ ps -A

Try to stop the packet forwarder, reset the lora card, then start the packet forwarder. This should occur on reboot
$ mts-io-sysfs store lora/reset 0
$ mts-io-sysfs store lora/reset 1

Check that the card hardware is functioning, cdone should go low when creset is low.
$ mts-io-sysfs show lora/cdone
$ mts-io-sysfs store lora/creset 0
$ mts-io-sysfs show lora/cdone
$ mts-io-sysfs store lora/creset 1
$ mts-io-sysfs show lora/cdone

There are several threads on TTN with similar issues and more discussion points than I can cover.
