RE: Locator Tag example fails at Fast Pair Validator App test "Scan/Connect timing"

Luca E. — Mon, 12 Jan 2026 11:01:31 GMT

Hi Susheel,

first thank you for your answer.

[quote userid="6207" url="~/f/nordic-q-a/126447/locator-tag-example-fails-at-fast-pair-validator-app-test-scan-connect-timing/558399"]The phone might be falling back to the 2 s interval.[/quote]

What do you mean by this interval? If the DUT is not allowing to pair after receiving an Account Key, it should not work after a delay of 10s, or am I missing something? I only found a factory reset schedule which expires 5min after receiving the first account key.

[quote userid="6207" url="~/f/nordic-q-a/126447/locator-tag-example-fails-at-fast-pair-validator-app-test-scan-connect-timing/558399"]Fast Pair advertising is only enabled when the pairing‑mode trigger is active[/quote]

Fast Pair advertising is enabled, but in the not-discoverable state. Which is the same as in Clock-Synchronization mode, as far as I understand, so it is not allowing to pair to a new phone.

Pressing Button 1 after a disconnect produces the Log message: "I: Fast Pair: pairing mode change is not available when the Account Key is in the NVM storage" and does not change the test outcome.

[quote userid="6207" url="~/f/nordic-q-a/126447/locator-tag-example-fails-at-fast-pair-validator-app-test-scan-connect-timing/558399"]where fp_adv_pairing_mode_request is set to false and temporarily for testing set that to true[/quote]

I did this in fmdn_provisioning_state_changed and fp_account_key_written (inside the main.c) which led to the test passing.

Please find attached the log for failing test (fp_adv_pairing_mode_request = false) see L.137 where Button 1 was pressed.

[quote userid="6207" url="~/f/nordic-q-a/126447/locator-tag-example-fails-at-fast-pair-validator-app-test-scan-connect-timing/558399"]Make sure that the phone does not have any bonded paired entries for your device under test.[/quote]

I checked in the settings that there are no devices bonded (saved) on that phone.

Now that we have got the test passing, how do we proceed? With fp_adv_pairing_mode_request always set to true the device probably does not adhere to the FMDN guidelines, I would imagine.
