Airturn PED works. However this was the hardest to get working. In the end I had to install the Airturn app from the App Store, update my PED, then it worked as a BT-105 perfectly. Then I selected AirDirect mode in Network->Airturn Setup. Then I had to press the mode button on the PED once to set it to mode 1. Finally I had to select the PED in Devices and then the info button showed up indicating it was paired.
Airturn BT-200 works. Footswitch is 1,3,2,4 in sequence on the pedalboard in Settings->Network->Airturn Switch Assignments. Use AirDirect mode 1.
Coda Music Stomp works perfectly as a BT-105. Just need to pair in the Bluetooth settings of the iPad.
iRig Blueturn works as a BT-105.
iRig Blueboard Still works perfectly. Pair with Blueboard App. Use the standard Blueboard proprietary mode.
