Thank you for support. Yes changed ble_enable_params.common_enable_params.vs_uuid_count = 3 as suggested by Jørgen Kvalvaag and also Increased ram size as provided by Link by Petter Myhre fixed the issue

Hi,

in my case, changing the value of ble_enable_params.common_enable_params.vs_uuid_count to a value different value then 1, causes the sofdevice_enable() to return with "NRF_ERROR_NO_MEM".

Is there anything else to be changed when this parameter is changed?

Hi, this example ble_stack_init() shows how to set vs_uuid_count:

ble_enable_params_t ble_enable_params;

err_code = softdevice_enable_get_default_config(CENTRAL_LINK_COUNT,
                                                PERIPHERAL_LINK_COUNT,
                                                &ble_enable_params);
if (err_code != NRF_SUCCESS)
{
    return err_code;
}
// This is your line, if you have 3 vendor spesific uuids:
ble_enable_params.common_enable_params.vs_uuid_count = 3

//Check the ram settings against the used number of links
CHECK_RAM_START_ADDR(CENTRAL_LINK_COUNT,PERIPHERAL_LINK_COUNT);
// Enable BLE stack.
err_code = softdevice_enable(&ble_enable_params);
...

Thank you Jørgen Kvalvaag .We can change vs_uuid_count value in softdevice_enable_get_default_config function? Is there any other method to change the value?

NRF_ERROR_NO_MEM means your BLE configuration does not allow for more vendor spesific UUIDs to be added. Solution is to set p_ble_enable_params->common_enable_params.vs_uuid_count = 3 before calling sd_ble_enable() in ble_stack_init()

Am getting error No Memory in both cases from sd_ble_uuid_vs_add call

am starting three custom services with different UUID and for DFU service ,UUID given by Nordic at devzone.nordicsemi.com/.../group__dfu__ble__service__spec.html. All 3 custom services start without DFU service enabled,but none of custom services are starting when after starting DFU service

can you also check the parameters in call to sd_ble_enable() p_ble_enable_params->common_enable_params.vs_uuid_count. Sounds like you have configured max vs uuid count to 1, and are now trying to add 2 vs_uuids

can you include your code where you add your custom service and DFU service? Maybe you are using the same UUID?
