Hi Petter,

i need to send my log when the app is connect to device. My log is send with indication because i need to know is all is received from app. But i need know if the cccd is enable from client, i don't understand how the sd_ble_gatts_value_get() works.

What is that you don't understand with sd_ble_gatts_value_get()? Please be more specific.

sd_ble_gatts_value_get() is the third option of your link. " 3. Read the value of the CCCD using sd_ble_gatts_value_get(), and check whether it is 0x0001 (Notification) or 0x0002 (Indication)."

Yes. I know. What is the problem?
