Can I set the value of "ATT_Write_Response", when peripheral receved "BLE_GATTS_EVT_WRITE"?
No sure if I understand your question correctly.
Maybe you could elaborate on what you want to acheive?
Best regards, Joakim
Also, on a general basis;
Information about what device, SDK, softdevice etc. that you are working with would be useful to include when asking questions.
Cheers.
