Hung up on advertising

[Lee Daniel Crocker]

I'm migrating an old (but working) app from the S110 5.2.1 (SDK 4.X) to the latest SDK9/S110 8.0. I've read the migration doc, and I'm following the examples carefully (specifically app_hids_keyboard, app_uart, and app_hrs). All my init functions are happy: timer, scheduler (with the new APPSH stuff), softdevice (using SOFTDEVICE_HANDLER_APPSH_INIT), everything comes up nicely. Scheduler works.

Then, I call ble_advertising_start(), I get a single BLE_ADV_EVT_FAST, then never another event of any kind. My phone can't see it advertising like it used to, and I never get any errors or anything--just quiet.

The major difference I noticed with my old code is that is has the sec_params_init() and responds to BLE_GAP_EVT_SEC_INFO_REQUEST, while most of the demos respond to that with a BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP. I never get that event in any case. I noticed that the device manager seems to make those similar security settings, but when I add it into the mix, I don't even get the first advertising event I was getting.

I'm really at a loss what to look for to debug this: If I get errors, I can see them; if I get events, I can see them. But I'm getting nothing.

I removed the extra pstorage_init(). I appreciate the generous offer, but I'd be more interested in learning how to debug this myself. I can add traces to the C code for most of the library, but the softdevice is a black box. It's not sending me any events, but is there any other way to probe its state, or otherwise peek under the hood?

static void softdevice_init(void) {
    SOFTDEVICE_HANDLER_APPSH_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, true);

    ble_enable_params_t ble_enable_params = {
        .gatts_enable_params = {
            .service_changed = IS_SRVC_CHANGED_CHARACT_PRESENT,
            .attr_tab_size = BLE_GATTS_ATTR_TAB_SIZE_DEFAULT
        },
    };
    uint32_t err_code = sd_ble_enable(&ble_enable_params);
    APP_ERROR_CHECK(err_code);

    err_code = softdevice_ble_evt_handler_set(ble_event_dispatch);
    APP_ERROR_CHECK(err_code);

    err_code = softdevice_sys_evt_handler_set(sys_event_dispatch);
    APP_ERROR_CHECK(err_code);
}
