Auto-resume After Wake

Overview

The plugin includes an “Auto-resume after wake” feature that can automatically re-enable Bluetooth when your device wakes from sleep if Bluetooth was enabled before the device was suspended.

Enabling Auto-resume

1. Go to Settings → Network → Bluetooth → Settings
2. Toggle “Auto-resume after wake” to enable or disable the feature

How It Works

When auto-resume is enabled:

1. When your device suspends, the plugin automatically turns off Bluetooth to save battery
2. If “Auto-resume after wake” is enabled and Bluetooth was on before suspend:
   • The plugin will automatically turn Bluetooth back on when the device wakes
   • It will attempt to reconnect to previously connected devices
   • Your key bindings will remain active
3. If the setting is disabled, Bluetooth will remain off after wake and you’ll need to manually re-enable it

WiFi Interaction

When Bluetooth auto-resumes after wake, the plugin needs to temporarily enable WiFi (MTK Bluetooth requires WiFi to be on). The plugin handles WiFi restoration based on KOReader’s “Auto-restore WiFi after resume” setting:

• If KOReader’s “Auto-restore WiFi” is disabled, WiFi will be turned back off after Bluetooth finishes enabling (since WiFi was only enabled temporarily for Bluetooth)
• If KOReader’s “Auto-restore WiFi” is enabled, WiFi state will be managed by KOReader’s own restoration logic

This ensures that enabling Bluetooth doesn’t unexpectedly change your WiFi preferences.

Battery Considerations

When auto-resume is disabled:

• Bluetooth will remain off after wake
• You’ll need to manually turn Bluetooth back on using the menu or a dispatcher action
• This can help save battery if you don’t need Bluetooth active all the time
