Thanks for the quick reply. I included a screen shot of the error I received on my post, that may not be visible. Here is the exact text. I will try to upload the screen shot again.
An error occurred while communicating with the H9 Device
The stompbox is not responding. Please verify that it is still connected.
(Error code MessageConstants::sm_response_timeout)
I am using an iPhone 5 for the update via Bluetooth.
I successfully updated my other H9 immediately before trying several times to update my other one using the same iPhone.
