How to enable CCCD automatically in NCS(zephry)

[stars]

Hi

Develop peripherals.nrf devices do slave machines.

Due to project requirements. The standard (notification) operation process needs to be changed (In the absence of binding).The following blogs have confirmed that the project needs can be achieved in the SDK：

SDK added as follows：

The SDK test meets the requirements.

But eventually I need to implement this functionality in NCS, so I want to know how to implement it in NCS. Currently, I can't find an API like sd_ble_gatts_sys_attr_set in the NCS list of GATT layer apis:

I need your help. Thank you very much!

Hi Einar Thorsrud，

I used NCS_2.3.The SDK I use is SDK_17.1.

This is determined directly when CCCD is not enabled on nrf_connect, as in SDK_17.1. The nrf device sends the data directly to see if nrf_connect can receive it.

Hi Stars,

It is not entirely clear to me what the issue is now (if any). Perhaps you can elaborate?

Hi,

Using the soifdevice in the SDK to disable CCCD, the nrf connect terminal can still receive data. But how do you change it in NCS.Just like in SDK_17.1

Hi Stars,

There is no API to manipulate the CCCD in non-standard ways in NCS.
