Can't SoftDevice recognize cccd?

[JoonDong]

I coded following

BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(&cccd_md.read_perm);

BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(&cccd_md.write_perm);

char_md.char_props.notify = 1;

char_md.p_cccd_md = &cccd;

and deleted everything that check m_nus.is_notification_enabled.

Then notification operation works well.

Is the cccd just one of attributes?

Is enabling or disabling notification done manually by checking m_nus.is_notification_enabled(reflected cccd value)?

But I heard descriptor(including CCCD) is also attribute, isn't it?

Yes, a CCCD is an attribute, but because setting it manually breaks the spec, it is not possible to do so. This thread explains it a little more thoroughly.

Thank you. It's very useful.
