SmartLock Ultra - WLAN, MQTT, Bluetooth - Weird issue

Hey together,

My SmartLockUltra works great with the keypad pro (fingerprint) and the App with Bluetooth. Much better BTW from the opening/closing mechanism as the former locks as the universal cylinder and the speed is much better now.

After activating Wifi and MQTT my iOS App can not connect anymore to the SmartLock. Wifi seems stable and working, but my App can not connect anymore (no matter if I am connected with my iPhone to WLAN or not).

I am still getting MQTT updates if I am locking or unlocking the door in my iobroker instance. So WLAN and MQTT works on the Ultra. But I am not able to connect for config changes anymore to my smartlock with the app.

Any idea? What can I try without loosing data?

Check if the phone can connect to the lock via Bluetooth (Phone in flight mode, with Bluetooth active).
If that works restarting the App several times (or the phone) might help
The connection info screen inside the Nuki App might also give you more information about the state of the locks server connection.

Hi

Thanks for your answer. Flight mode and Bluetooth works for the connection. Thanks for this hint. That helps for now, but does not solve the problem.

How can I update firmware of the lock then?
It seems like the lock is not able to establish a connection to the nuki servers? Why?

What can we do to check the issue of the lock and why the nuki server connection does not work?

If Flight Mode works via BLE the BLE connection to the lock should also work without, you just have to wait longer until the App gives up and falls back to BLE (>~10s)

You can try the compatibility mode or play around with expert settings as described in the FAQ: Smart Lock WiFi/Thread/MQTT connection troubleshooting / FAQ - #8 by Stefan_Reiterer

For individual support please contact the Nuki customer support, as this is not a support forum.

Waiting longer in the App does not solve the issue. I will open up a ticket with customer support.
Expert Settings did not do any changes.

What are the server names for NUKI?
Are there any logs I can get via Bluetooth from the Lock?
