Thanks for your reply
We currently have the Tek766 configured to confirm every 4th uplink. The factory setting for this device is an ACK every uplink.
The device is currently setup with ADR
Immediately after reboot
The Tek766 is transmitting every 30 minutes, the NAS pulse is transmitting every hour.
That’s a long story - Kerlink Wirnet Stations do not seem to work well on 3G backhauls (on ethernet they perform perfectly). The Gateway software does not seem to be aware when it drops the connection to TTN. The Wirnet is visible on Wanesy but not on TTN. A quick reboot makes the Wirnet visible on TTN again. The solution with Kerlink Support was to set up some form of cron job to automatically restart the Gateway packet forwarder every 30 minutes. Before this we were rebooting the gateway several times a day. Perhaps this is a subject for discussion in another post, however for the moment the solution provided by Kerlink seems to work. Restarting the packet forwarder every 30 minutes seems to take the Gateway about 2 seconds.
