 The Twiddler operates in both Wired, via USB, and Wireless, via 4.2 BLE.  When in Bluetooth mode, the Twiddler must be paired before it will start sending keystrokes and mouse data to your host device.

+===== 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|T14F2M]] to sequentially cycle through the Bluetooth Hosts currently paired with the Twiddler 4.

 ===== Automatic Discovery Mode ====
-Automatic Discovery Mode will pair with any of the hosts in your pair table. To enter this mode press T14F2M until all 3 LEDs light up.  The Twiddler 4 will be actively scanning for hosts.  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.

+Firmware 3.2:
+An additional mode that allows for connecting only to any known device is added to the rotation.  This will present show all three LEDs as either blue (peer device stored) or aqua blue light (empty), then will show a scanning animation until a device connects.  Pressing the [[t4_specialchords|Cycle Bluetooth Pairs Chord]] again will select the next single known device, pressing it again will move to the next known device, and continue until no more known devices are available.  The next mode is Automatic Discovery Mode, which also allows for new peers to connect; this mode is indicated by all three LEDs flashing blue quickly in unison.
