I am developing a WatchOS app for a companion Bluetooth speaker.
The device has typical the Play/Pause, Volume Up and Volume Down keys of a usual Bluetooth Speaker.
The following code works great at playing the audio, and I can control the volume using the up and down keys, but for some reason I can only stop the audio player using the Play/Pause button on the device. If I try to press the Play/Pause button again, nothing happens.
func playSong(song: Song) {
do {
try self.session.setCategory(AVAudioSession.Category.playback, mode: .default, policy: .longFormAudio, options: [])
} catch let error {
fatalError("*** Unable to set up the audio session: \(error.localizedDescription) ***")
}
do {
print("Attempting to play ", song.url)
let newPlayer = AVPlayer(url: song.url)
newPlayer.play()
self.player = newPlayer
} catch let error as NSError {
print(error.description)
}
}Is there a function or method I can listen on in order to implement the expected play/pause functionality?
I expect I'll have to handle the self.player.pause() events myself, which is no problem, but I can't find any reference for handling any Bluetooth Media Key events (except for the global Play Pause it seems).
