Getting Started
Starting the Watches
Charge your watch. Attaching the clip may cause the watch to reset. This is only for Beta units.
It is due to the Reset pin used for 2-wire JTAG (embedded debugging) being turned ON by
default.
Resetting the watch causes pairing information to be deleted. This (pairing information) will be
stored in Flash memory in the next revision of software. If you reset while paired, be prepared
for a new pairing request.
If you are using a large grey charge clip that has an 18 pin ribbon connector on the back, you
should attach your clip to the watch BEFORE applying power via the micro USB socket.
If you are using the small black clip with only a micro USB socket, then you should be able to
attach to the watch however you like. It may be possible to short the power against the steel
case back; there are protections in place to limit any damage, but you may notice the clip
getting hot if this occurs. Try to verify that everything is seated correctly and that the watch is
charging.
Digital Watch
There are 6 buttons on the digital watch. When booted the digital watch has these functions
(mostly for demonstration and debug). The watch boots in a “radio mode”.

Analog Watch
There are 3 buttons on the Analog watch. When booted the analog watch has no UI functions.

This is a temporary situation. There will be a default analog watch UI similar to the digital watch
UI.
Starting the Android APK (Meta Watch app)
Enable 3rd party app installation from Unknown Sources; this check box is found in Settings>Applications on Nexus S OS 2.3.
The APK file can be installed by installing from a GMAIL account or by loading on the SD card
via USB and then browsing for the file using a file manager application. We use Astro File
Manager.
Once installed, you should be able to open the app (named “MetaWatch”, press the Android
Menu button and go to “Settings”.
1. Under the ‘Notifications’ title, you can check or uncheck the items you want pushed to
the watch. Some are experimental, such as Gmail and Alarm which do not have official
APIs from Google to get reliable information.
2. Under the ‘Device’ title; use Select Watch to discover and select your watch. Be sure
your phone has Bluetooth turned on. You should see your watch’s MAC address
displayed on the phone. Alternatively, you can use the MAC button to manually enter
your MAC address. Skip this for now.
3. Under the ‘Other’ title. Here there are two experimental check boxes for the digital
watch only, one labeled “Music Controls” which turns the buttons on the the 9 o’clockside of the watch (D, E, and F Idle buttons) into a music control cluster. The other is
labeled “Last Notification Replay” which turns button B into a signal to the phone to
replay the last notification you received again (does not replay transient notifications like
calls or alarms).
Select the “font size” and “weather location” that works best for you. The weather location is a
free form field, you should be able to put a city, or zipcode. It requires an HTTP data connection.
The “Packet Wait” setting is for debugging and should be set to 0 (zero).
“Invert LCD” changes the LCD from White on Mirror to Mirror on White. Play around with it to
see what you like best, but implementation is incomplete and may require you to start and stop
the Meta Watch APK service.
Keep ‘Skip SDP Lookup’ unchecked. It is for debugging.
‘Test SMS loop interval’ is for debugging.
Press ‘Back’ to go back a screen.
Pairing and Connecting
Here is the procedure:
