Read a lot of data from NRF51822 over BLE

Question

I'm going to make temperature logger in NRF51822.
I want to use ble_app_uart as reference.
When mobile app is connected I have to send kilobytes of logs.
Now I use ble_nus_string_send to send chunks of logs.
And I call ble_nus_string_send from timer interrupt each 10 msec.
Of course it is not optimal. I have to get maximum baudrate.
I need BLE transmission complete event for example.
Does it exists?

There are multiple post on the forum explaining how to send notifications as fast as possible already. Here is one example. See sd_ble_gatts_hvx for details.
