The Bluetooth Gizmo That Costs More Than Your Coffee Addiction

The BT-105 is the name of the module used on classic AirTurn two & four pedal units. This screen shows the power & LED indicator light on the back of the BT-105 module.

Keyboard That Lives in Your Screen

Surprise! When you're rockin' a Bluetooth foot pedal, that iOS on-screen keyboard? Yeah, it ghosted you. This is because most Bluetooth foot pedals pretend to be a computer keyboard, so iOS is all "nah, we don't need that keyboard on screen, fam." You can drag that keyboard back into existence by jabbin' the red power button on the back of the module. You're welcome.

Baby Steps

This screen has numbered steps you can follow to turn your device on, pair it up & configure it so it actually does stuff. Tap each step to watch a lil' LED status light show. It's basically a rave. A tiny, foot-pedal rave.

The Actual Manual

Or hey, if you're feelin' fancy, read the whole bleepin' manual right here on this screen. Tap "Manual" in the upper right corner & pretend you understand electronics. We believe in you.
