Weird glitch # 117: iOS Bluetooth bug?
I have so much advanced technology in my home right now...that it seems something must go wrong every day. Often inexplicably. Here's the latest:
I have a Clavinova CLP-645 piano with Bluetooth. Both my iPhone and iPad have been paired to the piano and use it as a Bluetooth speaker if I choose. They automatically connect to the piano as soon as I turn it on.
At least my old iPad Pro did. Now, the iPhone continues to work fine with the piano. But my NEW iPad Pro 11" (replacing my old one) does not work right in this regard. In particular:
1. After having been paired, it will not connect with the piano either automatically (when turned on) or manually. If I select the piano from the Bluetooth menu in iPad's Settings, I get an Failed to Connect error.
2. If I delete the piano from the iPad's Bluetooth list in Settings, I can re-pair it. It then connects and works fine until after the first disconnect. Then it's back to Point #1 above.
3. What makes this even weirder is that the new iPad does not show this symptom with any other Bluetooth device. And, similarly, the piano does not have this problem with my iPhone or other iOS devices. It's just some weird bug that only occurs with the unique combination of my new iPad and piano.
Any ideas as to how to fix it?
Well I would still try resetting the network Settings as it does clear the preferences for both the WiFi and the Bluetooth items so just because you are not have any problems connecting to WiFi networks does not mean that clearing that setting would be a waste of time.
One other thing to try is to reboot the piano and see if that fixes it. If not, then your best bet would be to get in touch with Yamaha and see what they have to say about it as there really is no anything else that can be done from the iOS side of things.
If you read the linked HT from Apple about what happens when you Reset Network Settings you will see it clears the preferences for BOTH WiFi and Bluetooth and really is the only way to do that on iOS using the built in tools. Most likely you just have a bad pairing preference file for the piano. This is not an uncommon problem to have with bluetooth as I have seen it happen across platforms (macOS, iOS and Windows) and normally is not a bug in the Bluetooth driver. Not saying it is not possible, but from my experience it is a preference thing. So do not look for Apple to fix this as I do not think anything is broken in their software.
Great! Glad to hear that you got your problem solved. As to why you are not seeing the paring prompt on your iPhone X, if it is automatically connecting then it would make sense that it would not be prompting you. Yes, it is a bit odd that the iPad would be handling this BT connection differently but as long as it works that is the most important thing.
Sorry to hear that. I would see what Apple/Yamaha has to say as I would wonder if they have heard about this issue?
