Hello everybody,
I'm working in a project & need to listen for notification from installed applications in the mobile phone & update the mobile app with some info about the notification like app identifier for example, that would work for the android platform, but in IOS, it's a bit difference due to ANCS, ANCS listens for notifications, do analysis for the notification & get the app identifier & I need to back this notifcation analysis to the mobile phone again, the problem here when I receive any notifcation, I got in ios lightblue "dismiss connection is stale" & after that it fails to connect to the device again:
here is the code example :
/**@brief Function for setting up GATTC notifications from the Notification Provider.
*
* @details This function is called when a successful connection has been established.
*/
static void apple_notification_setup(void)
{
uint32_t err_code;
nrf_delay_ms(100); // Delay because we cannot add a CCCD to close to starting encryption. iOS specific.
err_code = ble_ancs_c_notif_source_notif_enable(&m_ancs_c);
app_error_check ( err_code )
err_code = ble_ancs_c_data_source_notif_enable(&m_ancs_c);
app_error_check ( err_code )
}
/**@brief Function for handling the Apple Notification Service client errors.
*

if (p_attr->attr_len != 0 )
{
err_code = ble_notification_update(&m_notify, ancs_attr_list[p_attr->attr_id].p_attr_data);
if ((err_code != NRF_SUCCESS) &&
(err_code != NRF_ERROR_INVALID_STATE) &&
