The Pedal has a reset button  next to the charging port. Did you try to reset?

Michael:  I had not tried the reset button before your suggestion.  But based on your suggestion, I did.  AND IT WORKED!!!!  I cannot thank you (and the others that commented) enough for helping me work this out. I truly did not want to have to buy and have yet another piece of gear that was merely a duplicate of a fully functional piece of gear that I already have.  So you saved me from that, and I'm very grateful. For any others that might be following this tread because they've had a similar problem, I think that the combination of (1) decoupling the Donner from my iPad, and (2) activating the reset button on the Donner were what made it work.  Thanks again for sticking with me on this and getting the Donner up and running.  Much appreciated!
