Please go to iOS settings -> Bluetooth, and toggle Bluetooth off and then back on. After that, try to connect with the nrf connect app and enable notifications again. Toggling Bluetooth enable will clear the attribute cache and this might be necessary if you have been using the same board with different firmware.

OK weird. sd_ble_gatts_hvx now returns 8.

uint32_t NotifierService::UpdateValue(uint16_t value)
{
    if (!mStatusInfo->notificationEnabled)
    {
        return 0;
    }

    uint32_t err_code = NRF_SUCCESS;
    ble_gatts_value_t gatts_value;

    // Initialize value struct
    memset(&gatts_value, 0, sizeof(gatts_value));

    gatts_value.len     = sizeof(uint16_t);
    gatts_value.offset  = 0;
    gatts_value.p_value = reinterpret_cast<uint8_t*>(&value);

    // Update database
    err_code = sd_ble_gatts_value_set(mStatusInfo->connectionHandle,
						    mStatusInfo->customValueHandle.value_handle, 
						    &gatts_value);
    if (err_code != NRF_SUCCESS)
    {
        return err_code;
    }
    
    // Send value if connected and notifying
    if ((mStatusInfo->connectionHandle != BLE_CONN_HANDLE_INVALID)) 
    {
        ble_gatts_hvx_params_t hvx_params;

        memset(&hvx_params, 0, sizeof(hvx_params));

        hvx_params.handle = mStatusInfo->customValueHandle.value_handle;
        hvx_params.type   = BLE_GATT_HVX_NOTIFICATION;
        hvx_params.offset = gatts_value.offset;
        hvx_params.p_len  = &gatts_value.len;
        hvx_params.p_data = gatts_value.p_value;

        err_code = sd_ble_gatts_hvx(mStatusInfo->connectionHandle, &hvx_params);
    }
    else
    {
        err_code = NRF_ERROR_INVALID_STATE;
    }

    return err_code;
}

How to view the log?

RE: nRF Connect app upgrade

Vidar Berg — Tue, 12 Dec 2023 07:26:23 GMT

Thanks for confirming. Could you please post the log from the nRF Connect app after you have enabled the notification?

RE: nRF Connect app upgrade

Yes, it does after the notification has been enabled in the app

There are no known issues with receiving notifications in the app. Have you checked whether sd_ble_gatts_hvx() returns NRF_SUCCESS?

Fair.
Since the upgrade, I haven't been seeing Value attribute in the BLE service modifying despite being set via

sd_ble_gatts_hvx 



Can't upload photos (nrf website being buggy)

To add, swipe right/left when you run into this bug on the old version of the app, those tabs will populate.

Hello, this was a bug in version 2.7, but should be fixed in 2.7.1. Version 2.7.2 is available on the app store now.
