问题:

I am making android BLE app. As per the Documents, I make application. My Problem is that sometime the app will work good , but sometime it throw the errors .There is 2 logs, one for success and 2nd for the errors. Every time bluetooth disconnect, i am send close method. I don't know where I am stuck.

1st success log

As in above Logs , the 1st display the data but in 2nd i got the issue of status 8 , it will happen after 3 or 4 successful connection .My thought is that, If there is issue in the code then it is not given me single success connection.

The issue that happens is resolved by me.

I have seen there are many question related to status 8 and 22 that occurs when we connect to device. I am saying that this is exact answer for status 8 and 22, but in some case it will be reason.

This happens because when we successfully discover the services, we write the descriptor and immediately call the ondescripte override methods and then read and write operation. So what happen, duw to not excecution of one process may create these problems.

The solution that I have found is working great. Always try to make Looper Handler, so that I make some delay to complete one execution.

       new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                mBluetoothGatt.writeDescriptor(RTS_CCCD); //for descriptor
  //  or
    mBluetoothGatt.readCharacteristic(brspInfo); //for read
//or
    mBluetoothGatt.writeCharacteristic(brspInfo); //for write
                            }
                        }, 500);

Why and what status 8 issue here.

Why and what status 22 issue here.
