Result of Python Script

[DecryptLocations] Decrypted Locations:
No locations found.

Also getting Location unavailable error on phone. - It keep respeating

Device is showing on both python list and phone application

Any thoughts? Feels so close

Built on mac using 5.4 or toolset

As stated in the README, locations cannot be viewed in the Find My Device app.

Google's network is not the best, you need to be patient if you are located in a less-populated area.

One additional thing: Did you use the ESP32 firmware or the Zepyhr firmware? I'm asking because the Zephyr firmware was not written by me, and I didn't have the time to test it yet.

Did you verify with a Bluetooth scanner app that the ESP32 is indeed sending out Bluetooth frames? nRF Connect is a good app for that, or AirGuard.

@billybigpotatoes C6 supports only BLE and not classic bluetooth, so the code won't work.
I did a pull request that makes the code work for a C3 (because I have some at home on which I could test), and that should work for your C6 also.

Hello, I am getting this using ESP32-C3 and ESP-IDF firmware on release/v5.4 branch:

3. GoogleFindMyTools µC: 67c74126-0000-287b-997d-94eb2c1af6e0

If you want to see locations of a tracker, type the number of the tracker and press 'Enter'.
If you want to register a new ESP32- or Zephyr-based tracker, type 'r' and press 'Enter': 3
[LocationRequest] Requesting location data for GoogleFindMyTools µC...
[FCMReceiver] Listening for notifications. This can take a few seconds...
[LocationRequest] Location request successful. Decrypting locations...
----------------------------------------
[DecryptLocations] Decrypted Locations:
No locations found.

I can see it in FindMyDevice app on the phone, but the location is unavailable there too. I can see it in nRF app as well.

Did you verify that Find My Device works with regular trackers? Maybe it is not available in your area yet or there are too few devices.

This is mine for reference

It will take time to show up.
Do we know the best case latency? on apple it's 10-30minutes

Did you enable scanning for FindMy app?

Ok, I left it on over night and now I can see locations in the Python script.

Check if it's similar to mine in nrf app.

even though the office is full of people I only get 2-3 reports/day, apple seems a lot better for now.
