Ive bought a cheap bluetooth headset to give it a whirl on the erm spare bike and Im now sure its definitely the way to go
What Im asking the few who already have a Bluetooth headset is... do you still get a trigger delay with the expensive ones ie scala rider etc as you do with a cheaper one ????
The main selling points with the expensive stuff is the quality of the mic and the life of the battery but nothing is mentioned in the blurrb about the trigger ...
what the fook is he on about I hear you ask .....
Background: A bluetooth device must detect a preset amount of A2DP audio stream to trigger open a gate allowing the stream to actually play through the device. For users, this means roughly 1 to 2 seconds of audio can be lost at the beginning of a stream. The gate closes a short period of time after the audio stream terminates. Audio content is lost each time the gate must be triggered open. According to Apple, the trigger threshold is controlled by the bluetooth device manufacturer.
The trigger delay can be a significant problem for navigation apps with text-to-speech (TTS) enabled.
An instruction spoken via the RP1 built-in speaker has no delay and sounds like, "In one mile at the T junction turn right onto First Street."
But the same instruction over bluetooth loses words and becomes, "…tion turn right on First Street."
If something holds the gate open -- for example streaming background audio by iPod or Pandora -- then when a navigation app interrupts with a TTS instruction none of it is lost.
Anyone help me out here please
