pebblewatch

A Ruby library for communicating with your Pebble smartwatch.

The protocol implementation was based on the documentation at http://pebbledev.org/, the Python implementation at Hexxeh/libpebble and the .NET implementation at barometz/flint.

To Do

  • Basic protocol communication
  • Sending of messages (notifications etc)
  • Receiving of events (log, music control)
  • Full 2-way app message support
  • Firmware/app uploading
  • CLI
  • REPL

Installation

gem install pebblewatch

Usage

Make sure your Pebble is paired with your computer and set up as a serial port. We're going to need the path or index of the port, which in the case of OS X looks like /dev/tty.Pebble7F30-SerialPortSe for Pebble ID 7F30.

require "pebble"

# Create your watch using the serial port assigned to your Pebble.
watch = Pebble::Watch.new("7F30", "/dev/tty.Pebble7F30-SerialPortSe")
# You can also use autodetection if you're on OS X:
# watch = Pebble::Watch.autodetect

# The watch object will be on the receiving end of 3 kinds of events:
watch.on_event(:log) do |event|
  puts "LOG"
  puts "timestamp:  #{event.timestamp}"
  puts "level:      #{event.level}"
  puts "filename:   #{event.filename}"
  puts "linenumber: #{event.linenumber}"
  puts "message:    #{event.message}"
end

watch.on_event(:system_message) do |event|
  puts "System Message: #{event.message} (#{event.code})"
end

handler = watch.on_event(:media_control) do |event|
  case event.button
  when :playpause
    puts "Play or pause music"
  when :next
    puts "Next track"
  when :previous
    puts "Previous track"
  end
end

# Suddenly had a change of heart? Just cover your ears.
watch.stop_listening(:media_control, handler)

# To make sure we don't miss any events, we haven't connected yet. 
# Because we also want to *send* stuff to the watch, we will now.
watch.connect


# We can of course send notifications.
watch.ping
watch.notification_sms("Scarlett Johansson", "Hey baby, what are you doing tonight?")
watch.notification_email("Tim Cook", "RE: Final offer", 
  "All right, you drive a hard bargain. We'll pay $2 Billion for the whole shop and that is our final offer.")

# Or let Pebble know what we're listening to.
watch.set_nowplaying_metadata(
  "Artist you've probably never heard of",
  "Album released exclusively through SoundCloud", 
  "Song that doesn't suck per se but isn't great either"
)

# We can also do some maintenancy things, although there's currently no firmware/app uploading.
versions = watch.get_versions
puts "Normal firmware version:    #{versions[:firmwares][:normal][:version]}"
puts "Recovery firmware version:  #{versions[:firmwares][:recovery][:version]}"
puts "Bluetooth MAC address:      #{versions[:btmac]}"

# Fun fact: We don't have to wait for the results synchronously. (This works on every message with a response.)
watch.get_installed_apps do |apps|
  puts "Installed apps: (#{apps[:apps].length} of #{apps[:banks_count]} banks in use)"
  apps[:apps].each do |app|
    puts "#{app[:index]}/#{app[:id]}: #{app[:name]} by #{app[:author]}"
  end
end

# Dieting is not just for dogs anymore.
watch.remove_app(id, index)

time = watch.get_time
# Or asynchronously: watch.get_time { |time| ... }

# Time travel is just one method call away.
watch.set_time(Time.now + (365 * 24 * 60 * 60))

# This is mostly interesting for internal stuff, but since there's a :system_message event as well, I thought why not.
watch.system_message(Pebble::SystemMessages::FIRMWARE_OUT_OF_DATE)

# Yeah, I'd stay away from this one.
watch.reset


# If you're done sending messages but want the program to keep listing for incoming events, say so:
watch.listen_for_events
# Note that listening will only end when the connection is lost, so anything that comes after this call will only then be executed. 
# This will generally be the last call in your program.

# If we don't want to wait around and listen, just let the program exit or disconnect explicitly:
watch.disconnect

Oh, and if you want to do some lower level stuff, have a look at Pebble::Protocol which you can access through watch.protocol.

watch.protocol.on_receive(endpoint) do |message|
  # Do whatever
end

watch.protocol.send_message(endpoint, message)

Examples

Check out the examples/ folder for two examples that I actually use myself. They're kind of similar, but should give you an idea of how this whole thing works.
