connecting Casio CTK 810 to Android smartphone

[pzielony]

I'm trying to connect my Casio CTK 810 with my android phones (Android 6 on Samsung Galaxy Grand Prime and Android 7 on Samsung A3 2017) but it just doesn't work. It is either disconnecting second after I choose MIDI connection on my phone or it is doing nothing like I never plugged anything. Cables are fine, keyboard is fine, if I connect to my Laptop it works correctly.

Do you have any ideas? Any app I should use? Drivers?

I don't think Android supports MIDI connections. Even now.

Casio only supports iPhones and iPads with their keys as well as Windows and Mac Machines.

oh yes I know it is possible, there are plenty of instructions for that in the internet, like here this youtube video:

What kind of cable are you using to connect the pair up?

Dumb question the answer is USB, but what kind of USB?

It is a while since I used Android but at that time the USB cable had to specifically be an OTG type, that is On The Go, it is only these that allow two way communication.

You will have to check up on this to see if it is still the case.

It is standard USB B->USB A cable like this:

and an adapter USB A->USB micro like this one:

I also tried with cable USB B->USB C and to newer phone or with USB C->USB micro adapter... no luck

OK you have the OTG adaptor but sadly that may not be enough.

Not all Android devices actually support the function.

It seems that specifically with Samsung, some do and some do not and even within the same model it depends upon chipset and ROM kernel.

I fell foul of this with an Asus tablet quite a few years ago, if I plugged in the OTG adaptor and plugged a memory stick into the adaptor the tablet would not see it

I suggest you ring Samsung product support.

Or, consider buying an iPad.

About OTG, there is an app in google play that allows you to check if your phone is OTG compatible or not. Mine is but it is not helping.. I asked casio support about that and here is the answer:

"Regarding your question, we can inform you about
the following.

The CTK-810IN is not compatible with Android, but only with Windows.
In this case only with the Casio USB Driver, which can only be installed up to Windows 8.1.

I am considering buying an old iPad (where simply piano app would work) or hack into android drivers somehow..
