Send a response directly in the same "connection interval" in Bluetooth


For my application (which is based on the ble_thread_dyn_mtd_coap_cli example), I would like to be able to send a file (for an update) using bluetooth. To do this, I send a 100 byte data packet and wait for the acknowledgment before sending the next one.

I would like to send multiple packets (with responses) in a "connection interval" but by doing some tests, I notice that the responses are always sent in the following interval ...

In the following example, I would have liked to be able to send the reply (message number 7014) already at the time of message 7012.

Would it be possible to send a response directly in the same "connection interval"?

Thank you
