I see that you just posted about the same problem in this discussion: “Bluetooth issue with 2 H9s simultaneously”
Based on the whole discussion, it appears to be a problem related with apple recent update. Did you read the whole thing?
If you’re running under IOS 8.3 this is already mentioned there and sadly I’m not sure Eventide could fix something broken on the iPad side.
In any case I’m sure it would help if you confirm which iOS you have.
