Android: Multiple write command in a single connection interval

[masa]

Hello!

I am working with nRF51822 Development Kit and Nexus7(Android4.4.3). I would like to try a multiple write command in a single connection interval, but can't confirm it. A single write command in a single connection interval is OK. Is it possible to send a multiple write command on Android?

Your assistance in this matter is greatly appreciated.

Is the wait for next writeCharacteristic specific to a BluetoothGatt or to the whole Android SDK? For example, an Android device is connected with 2 BLE devices, each of them has a BluetoothGatt to write. Then for those 2 BLE devices, can we write them simultaneously?
