What's new in v0.1.1

• The board advertises as a keyboard, so it shows up in a Mac's Bluetooth settings. The iPad keeps its on-screen keyboard.
• Pair another device (About screen): releases the current host for 60 s so a second iPad, iPhone or Mac can pair.
• Pairing and keys-only screens now cover the Mac as well as the iPad.

v0.1.0

• Portrait UI: Now playing, More, Nothing playing, pairing and About; green accent.
• HID media keys plus an Apple Media Service client: app, title, artist, progress, volume, shuffle and repeat, plus skip ±15 s and like.
• Random static address with recovery from stale bonds; flip screen; backlight dims after 2 min; #alive heartbeat.

On a Mac it works as media keys only (macOS doesn't publish Now Playing to accessories). Unofficial; not affiliated with Apple or Spotify.
