Hi there,
I use this Yamaha bluetooth receiver/sender to go from my pedal to the ipad: https://www.yamaha.com/paragon/reviews/read.html?product_id=658440&sdbid=658440
Here's a good video, but note that he's using a wired MIDI connection and a TC Helicon pedal: https://www.youtube.com/watch?v=kHm95AIgHoA

Good luck!
