If i add a delay of one second, the app receive the indication. Maybe i must wait that the service discovered. I can try to use a db_discovery_module

PM_EVT_LOCAL_DB_CACHE_APPLIED occurs before BLE_GAP_EVT_CONNECTED, so is not the correct event to be ensure that the app Master control panel is ready to receive the indication. I think that the problem is The app because if i count the number of ack which receive is it correct.

Then I think you should be able to use the PM_EVT_LOCAL_DB_CACHE_APPLIED event instead.

Is it possible that the problem is the APP? Because if i count the ACK that arrived is correct. But in the log of app doesn't compare. The number of ack for me is the times number that BLE_GATTS_EVT_HVC occurs

I use a peer manager not the device manager.

Ok. Maybe you can use the DM_EVT_SERVICE_CONTEXT_LOADED event you get in device_manager_evt_handler()? Do something like:

if( p_event->event_id == DM_EVT_SERVICE_CONTEXT_LOADED)
{
    start sending indications
}

Yes, i have. i use a BLE Developer studio to create a custom profile and plug in for the Nordic SDK11 to generate the code for it. The softdevice is s132 version 2.0.0

So you have bonded. What example are you using? What SDK and SoftDevice version?

Hi Petter,

thanks for the answer. Yes, sure the data must be when indication is enable. But if enable it, disconnect the app (Nordic Master control Panel), and i reconnect the indication is enable, yet. So i don't need to enable it. But in this case the event send before is lost. How can i understand when the indication is enable? Is there an event or a function that after the connection allow to check if the indication is enable?

Thanks, Anna

You can only send indications and notifications after the client have enabled them, this is done by writing to the CCCD of the characteristic you want to indicate/notify.
