I have been successfully controlling AutoScroll start/stop and manual scroll with a homemade footswitch using Arduino ESP-32 via keyboard commands over Bluetooth. It works great except there are some locations that I cannot for the life of me get Bluetooth to connect to my iPad. It's seem like location dependent interface? Possibly other BT devices?? I'm pretty dependent on this so for a gig this is no good when it happens.
Is there any alternative to BT such as direct control via TCP?
Thanks in advance!
Most foot switches are really keyboards (a typing keyboard, not a piano keyboard) that send a limited number of key messages. Most commonly a keyboard connects by Bluetooth using the HID protocol, but it can also connect by USB. The PageFlip Firefly (2 buttons) and Dragonfly (4 buttons) can do both:

The other option is a foot switch that sends MIDI messages, and connects through a USB MIDI interface.
ok
I'll pursue migrating my arduino to direct via USB connection
thank you!
