Why DeviceSettings.uniqueIdentifier value has changed?

Since last firmware (5.90 for Fr645 case) the value of the uniqueIdentifier has changed. Maybe other devices are involved.

1- Why Garmin have changed a field supposed to be be constant?

2- Why is there any trace in firmware release note?

3- Why developers have any information for this kind of modification before a release?

That is annoying.

I just did a quick test using a side-loaded test app on my fr645m. I ran with both 4.10 and 5.90 firmware and it showed the uniqueIdentifier was 9b3b51...96ba4d in both cases. I also took a look at our…

OK, thank you again. I investigate in my side.

I have found the issue the unique identifier has not changed, the issue comes from a map I used to access some values of the uniqueIdentifier, I close the question and I open a new one.

uniqueIdentifier is unique based on the device itself as well as the app, and I think a store version of an app vs a side load may be different. Are you seeing something like that?

When you update to a new version from the store, it should remain constant though.

The implementation has not changed.

The value should be different for different devices (if you have two fr645 devices and you install the same app on both of them, the value will be different on each one), but will be consistent for the same device (the value won't change if you uninstall the app and re-install it).

I agree

Yes I agree, that s why I have chosen this attribute as unique device identifier. I use this id to give access to some web services. Since 3 days F645 Music users have a problem, they cant access to my web services, both have updated the firmware to 5.90, and all their id have changed. So I am bit woried.

This doesn't sound good. Do you have a way to verify the uniqueidentifier values they had before and after?

0 Juggus over 4 years ago in reply to HermoT

No, I cant verify. That is the facts:

1- This part of my code has not changed since 15 monthes

2- That would be the first bug (for this part of the app )

3- The last update of my app was the 30 may 2019

4- 5 users from different countries have the same issue (since friday)

5- they use my app since 2 or 6 monthes

6- all have a 645 Music

7- all have noted the issue after the 5.90 firmware update

If Travis said the implementation have not changed, the issue should be in my side, but facts are confusing.

Thank you fo all answers.

It is possible that the device team modified some configuration settings that would change behavior. I haven't looked into that.

Regardless, I've filed an issue for us to investigate further.

I also took a look at our testing, and we are testing that the uniqueIdentifier value produced is consistent for a given set of inputs.

Again, I've filed an issue for us to investigate further (WERETECH-7720). I've added a note to the ticket to report back here with our findings.
