About “Proximity 2.5” app
You can update the firmware of the watch through the “Proximity 2.5” app.
In the combination of an updated watch and the iPhone which registered it,
you can establish Bluetooth connection only using Bluetooth setting on the
iPhone.
In addition, once Bluetooth connection is established between the watch
and iPhone, you do not have to keep “Proximity 2.5” activated since the iPhone sends
notification to the watch following its own notification setting set by the app.
You can configure notification setting of each supported app from the iPhone to the watch
separately through “Proximity 2.5” as well as other settings.
