"""DisaBLE
|
|
~~~~~~~~~~
|
|
|
|
Disable BLE to save energy and enhance privacy.
|
|
|
|
This app shows the bluetooth status and provides a button to disable/enable it.
|
|
Unfortunately, re-enabling bluetooth normally has some issues, so as a
|
|
workaround the "enable" button restarts the watch.
