Cannot find CCC (Client Characteristic Configuration) Characteristic on DA 14681 device

Hello,

According to Software Developers Guide _5v0 .pdf of 14681, page number 48 and 49, to enable the notification from the board we have to write to the CCC. But there is no such CCC in my devices characteristics. I can see all other characteristic in the SUOTA service except CCC. Also nowhere in the documentation they have specified what should be written to CCC in order to enable notifications.

Hi vinesh_gowda,

If you are running the proximity reporter for example with the SUOTA enabled the characteristics that should have CCC attributes is only one (UUID_SUOTA_STATUS), if you connect via a generic BLE application then you should see the option of enabling the notifications. Also the enabling and disabling of the notifications is not Dialog defined but BLE specification defined, so the values that you should write are standard and defined by the spec.

Thanks MT_dialog
