in esp-idf bt stack is constructed like that:
- for gatt server all connected devices are using the same gattIf and different connId,
- for gatt client all connections to different servers are using different gattIf.

So, if you want to connect to few ble servers then you have to control all data exchange operations at first by gattIf and then by attr_handle.
