android ble connectGatt timeout

To save embedded device battery power, the advertising period is 10sec. With a Samsung tablet, I succeed to scan the device with a scan period timeout of 30sec.

When I try to connect to it, nearly every time the connection is fail (error 133). Sometime it is OK. I already looked for some posts so I try to connect with the TRANSPORT_LE option. I suspect a timeout during the connection procedure because it stops after 2 or 3 second only.

How can I specify a longer timeout for the connectGatt() procedure?

Here is some method I address with status 133.

I add this code in callback

onConnectionStateChange

else if ((status == 8 && newState == 0) || (status == 133 && newState == 0)) { 
                gatt.disconnect();
                gatt.close();
                gatt.getDevice().connectGatt(getApplicationContext(), false, mGattCallback);
            }

I just disconnect and release all bluetooth resource with gatt.close(). Then reconnect with it again.
