DFU Service and Custom Service

[Srikar]

Hi, Am starting custom service to support custom profile and it works without any issues. But when I add DFU service also to start after custom service DFU service fails to add the service. If I start custom service after DFU service ,custom service is not starting. Am using NRF52 dev kit with Softdevice 2.0 flashed first and application . Please let me what may be reason for failure. I can see sd_ble_uuid_vs_add is returning error in either case

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);

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?

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
