many thanks for your information about the unclean disconnection,
my critical TTIG, which used to fail reconnecting after a powerfail or WLAN break is online since yesterday 13:00 o clock. After an outage today (I think WLAN) at 12:15 it reconnected at 13:00 without my intervention. I think your fix could have been successful. I’ll watch this behaviour the next days and will report it here.
2020/02/21 7:30 … by chance I saw at the moment my TTIG blinking red/green … means it had lost WLAN Connection and was establishing it again. After shortly blinking fast green the LED got solid green … means established connection to CUPS and configured correctly. Looking at TTN Console there was an outage of about 10 min. Perfect … I think and hope, the issue I described above is solved. Many thanks…the timeout of 600 instead of the initially 60 seconds isn’t a big problem for me and my apps.
My problem seems, as mentioned above by TD-er, WLAN disconnects, which I’ll try to minimize now. I’ll establish an AP of its own for the TTIG, operating BG only.
My second TTIG, connected to a corporate WLAN, which is switched off every night, runs stable the last two days … also a big improvement. This device was implemented for testing purposes only and will be switched off within the next 2 weeks.
