You need to register a developer account with google for them to add your email account to the list that will get a pop up from development devices. Please see this ticket:

Hello, I am having the same problem. I am using v2.7.0 with both unchanged input device and locator tag example. The UART log shows discoverable advertising started and I can indeed sniff the advertising packets, but I have tried with a Google Pixel 7 as well as other devices and there isn't a pop-up window that comes up. Could you help me debug this issue? Thanks in advance!

I am not familiar with the github repo that you refer to. That is not an official Nordic Semiconductor account.

Did you try to register a developer account with Google and use your own set of keys?

Hello Edvin,
I am using the default Fast Pair: Input Device sample without any changes,
If I use any of these model id (https://github.com/DiamondRoPlayz/FastPair-Models) I can see the pop up but because of the wrong antispoofing key, it fails.

Hello Nandy,

Can you please try to register an account with Google and use your own Model ID and spoofing keys?

And can you please try out the unmodified Fast Pair: Input Device sample from NCS? Does that work with: 1: Debug keys from nordic, and 2: your own keys?

BR,
Edvin

Hello,

Can you please try to use either NCS v2.6.1 or v2.7.0, as those are stable releases. The v2.7.0 rc1 is the first out of 3 release candidates, which means it is not stable. So unless you particularly need a feature that is just released in a release candidate, please stick to a stable version of the SDK.

Let me know if it doesn't work in NCS v2.7.0. In that case, please share your build log and your nRF52840's (uart) log.

Best regards,

Edvin
