Adding DFU service support. Error 4 when calling ble_dfu_init()

[mosi]

My application uses the following:

• Proximity Profile (including Link Loss Service, Immediate Alert Service, Tx Power Service)

• Battery Service

• My own custom service with a 128-bit UUID (including 4 characteristics)

The application has worked so far.

Now I try to add DFU service support to my application.

But when calling ble_dfu_init() I get error 4.

Error 4 = NRF_ERROR_NO_MEM (No more free slots for VS UUID)

What can I do to solve this?

I found an answer. Go to softdevice_enable_get_default_config().

uint32_t softdevice_enable_get_default_config(uint8_t central_links_count,
                                              uint8_t periph_links_count,
                                              ble_enable_params_t * p_ble_enable_params)
{
    memset(p_ble_enable_params, 0, sizeof(ble_enable_params_t));
    p_ble_enable_params->common_enable_params.vs_uuid_count   = 1;
    p_ble_enable_params->gatts_enable_params.attr_tab_size    = SOFTDEVICE_GATTS_ATTR_TAB_SIZE;
    p_ble_enable_params->gatts_enable_params.service_changed  = SOFTDEVICE_GATTS_SRV_CHANGED;
    p_ble_enable_params->gap_enable_params.periph_conn_count  = periph_links_count;
    p_ble_enable_params->gap_enable_params.central_conn_count = central_links_count;
    if (p_ble_enable_params->gap_enable_params.central_conn_count != 0)
    {
        p_ble_enable_params->gap_enable_params.central_sec_count  = SOFTDEVICE_CENTRAL_SEC_COUNT;
    }

    return NRF_SUCCESS;
}

Change:

p_ble_enable_params->common_enable_params.vs_uuid_count   = 1;

to

p_ble_enable_params->common_enable_params.vs_uuid_count   = 2;

This will allow for two Vendor Specific UUID.

Hai mosi,

Have good day. I following your previous question Add BLE DFU service when using Peer Manager?. IF you are complete dfu service in your Proximitty aplication please support.

Thank you.
