I am having problems getting my iPhone 4S (was my daughter's and only using it for the keyboard apps) to recognise my P115 keyboard.
Sent an online support request to Yamaha at 12:29 and received a reply at 12:38 saying everything I have done is correct so they suggest it may be a faulty cable and to contact the supplier which I have done.
