 ===== Multiple Host Pairing ===== ===== Multiple Host Pairing =====
  
-You can pair your Twiddler 4 with three separate Bluetooth hosts.  For security reasons, the Twiddler 4 will only connect to one host at a time. Use [[t4_specialchords|Use the Cycle Config Chord]] to sequentially cycle through the Bluetooth Hosts currently paired with the Twiddler 4.+You can pair your Twiddler 4 with three separate Bluetooth hosts.  For security reasons, the Twiddler 4 will only connect to one host at a time.

 +===Bluetooth Modes=== 
 + 
 +Cycle through the different Modes by pressing the [[t4_specialchords|Cycle Bluetooth Pairs]] chord. 
 + 
 +==Pairing (B-B-B)== 
 + 
 +When all three LEDs are blinking Blue at the same time, the Twiddler is actively looking for a host to pair with. Use this mode to add new hosts to the Twiddler. 
 + 
 +==Automatic Discovery Mode(B-B/A-B/A)== 
 + 
 +This mode has been designed for situations where you have paired with hosts that are in different locations and want to seamlessly transition from one host to the other when in range.  A good example of this is a work PC and a home PC.  If you pair the Twiddler with both, when you leave home, the pair is dropped when out of range of your Home PC and automatically paired when you get into range of your work PC. 
 + 
 +Press the [[t4_specialchords|Cycle Bluetooth Pairs]] chord until at least one of the LEDs is Aqua (light blue). This mode will only seek to pair with known hosts.  The number of known hosts are represented by Blue LEDs and empty pair slots are represented by Aqua LEDs.  All three LEDs will illuminate then cycle left to right, then right to left indicating that it is searching for a match. Once a match is found, the corresponding pair slot will briefly blink Blue and then all LEDs will go off. 
 + 
 + 
 +==Specific Pairing Slot (B--, -B-, --B)== 
 + 
 +To cycle to a specific pair slot press the [[t4_specialchords|Cycle Bluetooth Pairs]] chord until the 1 Blue LED illuminates in the 1st (left most) position. Pressing the Cycle Bluetooth Pairs chord again will advance the selection to the next pair slot, if it has been previously assigned. 
 + 
 +==Bonding (B-B)== 
 + 
 +When a host is in the process of pairing, the Twiddler goes through a bonding phase.  You will see LED 1 and LED 3 briefly illuminate to indicate this.
