You can debug your wearable over Bluetooth by routing its debug output to the handheld device that's connected to your development machine.

Setup Devices for Debugging

1. Enable USB debugging on the handheld:
   • Open the Settings app and scroll to the bottom.
   • If it doesn't have a Developer Options setting, tap About Phone (or About Tablet), scroll to the bottom, and tap the build number 7 times.
   • Go back and tap Developer Options.
   • Enable USB debugging.
2. Enable Bluetooth debugging on the wearable:
   1. Tap the home screen twice to bring up the Wear menu.
   2. Scroll to the bottom and tap Settings.
   3. Scroll to the bottom. If there's no Developer Options item, tap About, and then tap the build number 7 times.
   4. Tap the Developer Options item.
   5. Enable Debug over Bluetooth.

Set Up a Debugging Session

---

---

1. On the handheld, open the Android Wear companion app.
2. Tap the menu on the top right and select Settings.
3. Enable Debugging over Bluetooth. You should see a tiny status summary appear under the option:

   Host: disconnected
   Target: connected

4. Connect the handheld to your machine over USB and run:

   adb forward tcp:4444 localabstract:/adb-hub
   adb connect localhost:4444

   Note: You can use any available port that you have access to.

In the Android Wear companion app, you should see the status change to:

Host: connected
Target: connected

Debug Your App

---

---

Your wearable should show up as  localhost:4444 when running  adb devices. To run any  adb command, use this format:

adb -s localhost:4444 <command> 

If there are no other devices connected over TCP/IP (namely emulators), you can shorten the command to:

adb -e <command>

For example:

adb -e logcat
adb -e shell
adb -e bugreport
