Moto 360 Allow Wear Debugging

For some reason it only worked when my phone (Moto G5s) was in "charge only" mode when connected via USB. As soon as I changed it to "file exchange" the connection broke and ADB refused to connect to the smartwatch. After switching the phone back to "charge only" and restarting the adb console I could connect again using "adb connect 127.0.0.1:4444"

First of all become a developer on Moto 360 and enable Debugging.

1. Launch Settings
2. Select About
3. Tap on Build number until you become a developer :-)
4. Above will enable Developer options in Settings on your Moto 360

Enable ADB debugging and Debug over Bluetooth.

5. Under Developer options enable ADB debugging and Debug over Bluetooth
6. Launch Android Wear on your phone/tablet
7. Press settings (gear) icon
8. Turn on toggle button Debugging over Bluetooth
9. Connect your phone via USB and make sure USB debugging is enabled
10. Run adb devices from the command line.
11. If device called “localhost:4444” is listed, you are already paired and can continue at step 13.
12. From command line run adb forward tcp:4444 localabstract:/adb-hub then run adb connect localhost:4444
13. Launch Android Studio. When you launch your app your device should be available in the list for debugging in Choose device dialog under Choose a running device checkbox.

Hope this helps.
