Pebble adds Android Wear notification support with its update to version 2.35
Firmware version 2.9 adds support for Actionable notifications and Android Wear compatibility for those pairing their Pebble with a phone running Android 4.0 (Ice Cream Sandwich) or higher. Android users need to update their firmware to version 2.9 before they go into the Google Play Store and update to Pebble version 2.3. The update allows you to have five pre-written replies to notifications and also allows you to reply to a SMS message from your Pebble, using most Android compatible messaging apps. The update will also allow you to receive WhatsApp notifications and it allows for Automatic app and watch face updates when Pebble is idle. And of course, there is the usual bug fixes and stability improvements.
