when i send the data over Bluetooth why write exe event triggered instead of write event in ble

There is 2 types of write:
- GATT_WRITE_EVT - to send/write partially data, in case the data is longer than MTU
- GATT_WRITE_EXEC_EVT - to inform when data write is finished, which means all data are already transferred

Actually if the data size is less than 23 bytes write event was triggered but if its greater than 23 bytes write exe event triggered can i know why?
