Difference between Bluetooth Classic 'On' and 'Pair'

[czarcasm]

Topic is pretty self-explanatory, but...what's the difference between the settings 'On' and 'Pair' for Bluetooth Classic?

Thanks in advance.

Pair sets the BT to visability mode so that when you ask the phone to search, it will be able to be found.  

On is just that, it is the opposite of off, and will only be detectd by phones already paired

Got it.

Thanks again, you're quite helpful in these forums.

I don't know, but pair is only to be used for the initial setup of the Bluetooth Classic with your phone. Once the phone and tracker are paired you want to change it to On.

New user here and I've having trouble keeping the Classic Bluetooth on. When I check it, it says off. So I typically keep it on Pair. The only options I can choose from is pair or off.

What phone do you have  @Pinkjen?

Are you trying to control music on your phone with the tracker?

A warm welcome to the Community @Pinkjen and @Rich_Laue thanks for stopping by.

Is your tracker is updated? If it isn't, I recommend update it by following the instructions provided in the How do I update my tracker's firmware? post.

I hope this helps, let me know the outcome.

This is quite poor. The documentation that ships suggests that "Bluetooth classic" is an older spec "stack" (or older standard) and that "classic off" does not disable Bluetooth but enables contemporary settings for Bluetooth rather than legacy.  Otherwise why say "classic" at all?

This doesn't answer the question. Can you please give us an explanation or provide a link with documentation?

Thank you

For a quick explanation see fitbit's searchable interactive help docs. 

Bluetooth classic is what use to be called Bluetooth, the typical Bluetooth used for connecting to speakers. 

With the release of Bluetooth 4.0 there was a new protocol called Bluetooth Low Energy(BTLE). At this point to distinguish between the two types the common Bluetooth was renamed Bluetooth classic. 

https://en.m.wikipedia.org/wiki/Bluetooth

Fitbit tracker a all use BTLE to sync the data. 

Three tracker a Surge, Blaze, and Ionic have both Bluetooth classic and Bluetooth Low Energy. The classic is used for music control and in addition with the ionic headphones may be attached. 

Do yes Bluetooth classic protocol may be turned off if music control is not desired, this however does not turn off BTLE which is needed to sync the tracker. 

As for Bluetooth on/pair, as with keyboards speakers, etc all Bluetooth classic devices have a pairing mode which allows a BT server to see the device, without the pair a user will never be able to properly set it up to a phone.

I have paired my blaze to my cell phone. If I go into my phone app it originally showed it synced. Later when  I check it shows it isn't. When I go to the Blaze, it shows the Bluetooth classic off. When I turn it back on, the phone and watch will sync. Why does the Bluetooth classic keep turning off?  I thought that once a device was synced, it stayed that way.

[Rich_Laue]

@txyank without knowing the phone you use I can not answer your question. 

Bluetooth Classic is only used for music control. The sync process uses Bluetooth Low Energy which can not be turned off. 

An iOS device does not use Bluetooth classic so when connected to such a device classic gets turned off.

Rick,

I have the LGL43AL phone using the Android operating system. But since you said that the Bluetooth Classic is for music, that answered my question and I won't worry about it as I won't be listening to music on my watch. Thanks for your quick response.

[dsantil71]

Thank you, this is exactly the answer I was looking for!!

[Rich_Laue]

@txyank BT Classic is not for listening to music on the watch, but for the Blaze to control the music your listening to that is playing on the phone.
