Nuki Bridge 2.0 Errorcode 15 WiFi broken

My Nuki Bridge 2.0 (or whatever the revised Hardware Revision from 2019 is being called) running Firmware 2.14.0 lost the WiFi connection. After a reboot it didn’t reconnect so I started the Nuki App to manage the Bridge.
The App reports that the Bridge is broken and Reports Errorcode 15. After several retries I can manage the Bridge and it looks like it doesn’t find any WiFi Networks anymore at all. A factory reset didn’t help at all.

Is there a bug with the Hardware of the Espressif ESP-WROOM-32 inside the bridge or a problem with the WiFi Firmware?

Error Message in German: "Diese Nuki Bridge ist leider defekt und muss ausgetauscht werden. Bitte wende dich an den Nuki Support. Fehlercode: 15.

Any ideas what Error 15 means?

The same thing happened to me 10 days ago. Any update that broke the product?

For me too: Fehler 15 / Error 15 with my nuki bridge. thats crap :frowning:

Nuki refuses to replace the product, this is obviously a software bug, not a hardware one.
I informed the seller (Tink) about that procedure and think it was my last nuki.
The original lock is already replaced, i used the Bridge with the Smartlock 3.0, which i bought 3 months ago at Amazon, luckily, i am able to return that crap.

nearly 3 Years of nuki seem to be enough.

This assumption is wrong. It’s a hardware defect and can’t be fixed with a software update.

That’s discussable. I will open it and extract the firmware and compare it with a brand new one.
But still: multiple customers are affected by this bug, which occurred in three cases ±7days
Planned obsolescence?

Then let us know what exactly is broken.
What does Error 15 means? Which component failed?
The Bridge consists of an ESP32: is there a Problem with this Part?
Maybe something in Common?
How comes so many brigdes fail at more or less the same time? Bad component or failed Firmwareupdate?

Most likely a problem with the power unit (transformer).

“Many” is relative. It’s 3 out of a 6digit installed base.

Thanks Jürgen for your reply.

I connected an usb-to-serial-adapter to the serial pin header on the nuki bridge and here’s what it shows.
Looks like a boot loop.
Can you tell whether your assumption on a broken transfomer is right or not from this output please?

A boot loop is what you usually see when an energy source does not deliver enough power to a circuit. So yes, still points to a defective transformer. You can simply replace the integrated transformer with any other 5V power source.

This would be the transformer


SMTSD S05P7-05W
This means, this is a 5 volt transformer with 1amp current.
That cheap china transformer caused those errors?


That’s a bit below that 5 volts, indeed.
Anyhow, USB (best source for stabilized 5 volt power supply) does work

Cheap parts means more complaints.
