ANCS Sample doesn't work after rebooting iOS Device

[Nori]

I'm testing ble_app_ancs experimental sample.

It seems working first connection. But after rebooting iOS Device, or Turn Off/On bluetooth function on iOS Device, ANCS does't work.

After delete bonding both evaluation board and iOS Device, it works again. Is there any infomation about this issue?

Testing Environment

iOS Device iPod touch 5th Gen. iOS 7.0.3 iPhone 5 iOS 7.0.3

BLE Board nrf6310 Rev 1.4 nrf6350 Rev 2.0 PCA10004 Rev 2.1.0 Softdevice 6.0.0-5beta

Hi Ole,

I found that I had to keep my code mentioned above:

case BLE_GAP_EVT_CONN_PARAM_UPDATE:
case BLE_GAP_EVT_AUTH_STATUS:
apple_notification_setup();
break;

and, add the following:

ble_ancs_c_t * timer_p_ancs;

void timer_service_discovery(void)
{
    service_disc_req_send(timer_p_ancs);
}

static void event_discover_rsp(ble_ancs_c_t * p_ancs, const ble_evt_t * p_ble_evt)
{
    if (p_ble_evt->evt.gattc_evt.gatt_status != BLE_GATT_STATUS_SUCCESS)
    {
        // ignore failure - retry in one second
        //handle_discovery_failure(p_ancs, p_ble_evt->evt.gattc_evt.gatt_status);

        timer_p_ancs = p_ancs;
        // call function timer_service_discovery in 1000ms, don't repeat
        start_new_timer(timer_service_discovery, 1000, false);
...

This seems to allow notifications after bluetooth has been turned off and on, AND after the iPhone has been turned off and on.

Please let me know if you think this is a suitable work-around, or what needs changing and where about in the source.

Thank you for all your help so far, Paul.

This doesn't seem too bad, but I would consider to just retry a limited number of times, to limit current consumption in case the service is actually not there.

Also, I can't really give a proper verification of the code, so I suggest that you test this thoroughly yourself, to be confident that it works as expected.
