Master or Headset Modes
Master or Headset
Your cellular telephone is a good example of a device operating in
Master mode. In default mode your cell phone will see the Daptor
Three as if it were a headset. When the Daptor Three is in Master
mode, it can send stereo audio to stereo earphones or the Daptor
Three can be paired to a headset for full duplex conversations.
There are many different profiles available for Bluetooth communi-
cation. Any devices that you have interconnected must be pro-
grammed with the same profiles. Most newer cellular telephones
use any combination of Headset, Hands-Free and/or A2DP proto-
cols. A2DP is the only profile that will enable Daptor Three to send
stereo audio in Master mode so the headset device it is paired to
must be equipped with the same profile.
Switching to Master mode
When pairing to another Bluetooth enabled device, the Daptor
Three will connect in headset mode by default. If you want to
switch to Master mode, you must start from the Bluetooth power-off
state. Hold the MFB down for greater than 10 seconds but less
than 15 seconds, then release the button to change roles. The next
time a Bluetooth connection is enabled on your Daptor Three, the
Stereo LED will flash green to verify it is operating in stereo Master
A2DP mode. To toggle between stereo A2DP and mono Hands
Free profiles (which can only be done while the unit is in Master
mode), simply tap the MFB button once on the unit that is in Master
mode for each change of state .
The Stereo LED on the top of the Daptor Three will flash green
when the device is in Master mode and red when it is in Headset
mode. The timing of the blue LED while pairing with another device
should remain the same for either state. The red/green LED will
only light during power up or when streaming stereo A2DP audio.
When the Daptor Three is in Master mode, pairing to another Blue-
tooth device is somewhat different. Daptor Three will assume a
default Pin of 0000 on the slave device and will automatically nego-
tiate a connection. If the Pin on the slave device is different, Daptor
Three will not be able to pair with it.
The connection history will maintain up to 16 devices in Master
mode in addition to the 16 devices it keeps in the Headset mode
history.
