How to read using the classic bluetooth?

How do I read using the classic bluetooth? Not seeing anything in the documentation. Thanks

You should use the setOnEventCallback and then onDataRead.

Sample project.

Thanks for the quick reply! Im pretty new to Android/Java I have that implemented in my code but how do I get that to call.

Like for example I use service.write(byteArray[]) to write to the bluetooth device which in turn calls the onDataWrite(). Is there a similar way to call the read? Or how would I do that?

Thanks again, really appreciate it.

You need to read more about Bluetooth and asynchronous programming.

Receiving data via bluetooth is asynchronous, so there is no method for reading synchronously.

Just did some reading and I see. I am running BLE(can't seem to use BLE on the android version because the bluetooth module has a bug) on my IOS version of the app I'm working on so I was thinking it was setup like that, where I would read whenever I needed a value. It's just weird that I'm not receiving any data from the callback, since the device should be sending data constantly when connected. Will do some more digging, thanks.
