Hi,
I am trying to configure READ characteristic with notification attribute. At the moment I can see this characteristic on android app (nRF Connect) with properties READ and NOTIFY. On android app, I can't see the possibility to subscribe this characteristic. To update value in this characteristic, I have to press read button manually.
Is there any tutorial or demo/example that shows how to configure that kind of characteristic?
Best regards,
Witold

Hi Witold,
Please take a look at theDA1469x Tutorial BLE Custom Servicetutorial from our support web site. This tutorial demonstrates how to create a custom service which includes one characteristic declaration with write-read-notify access permissions. Please check step 5 in Section 2. In your case you should have GATT_PROP_READ | GATT_PROP_NOTIFY access permissions.
Thanks, PM_Dialog
Hi,
now I see my mistake. Every characteristic which uses notify must have descriptor.
Now it works!
Thanks,

Hi Witold,
Glad that you are able to create a characteristic with notify/write properties and thanks for accepting my answer.
Thanks, PM_Dialog
