sd_ble_uuid_vs_add error

[All4here]

Hello, i am using the Nrf52, i am facing problem on the following line

    #define MESH_SERVICE_BASE_UUID128 0x23, 0xD1, 0xBC, 0xEA, 0x5F, 0x78, 0x23, 0x15, 0xDE,     
                                                               0xEF, 0x12, 0x12, 0x00, 0x00, 0x00, 0x00
    ble_uuid128_t baseUUID128 = { MESH_SERVICE_BASE_UUID128 };
    err = sd_ble_uuid_vs_add(&baseUUID128, &meshService.serviceUuid.type);

sd_ble_uuid_vs_add return the error code 16. the Error code 16 is Bad memory Address.

this problem came from the gap_enable_parameters as i think. if i select the maxoutconnection to 3 then everything is ok but if i select this to 7 then i got this issue. i also would like to share the information about sd_ble_enable

Here is code for ble_enable

u32 __application_ram_start_address = 0x20003F30;

err = sd_ble_enable(&params, &app_ram_base);

using this address i have no error from the ble_enable.

thank you

To allocate enough RAM for vendor specific (custom) UUIDs, the correct number of such UUIDs should be provided to softdevice_enable(..) --> sd_ble_enable(..).

Setting the correct number of vendor specific UUIDs could be done the following way:

ble_enable_params_t ble_enable_params;
err_code = softdevice_enable_get_default_config(CENTRAL_LINK_COUNT,
                                                PERIPHERAL_LINK_COUNT,
                                                &ble_enable_params);
 ...

ble_enable_params.common_enable_params.vs_uuid_count = 3; // set number of vendor specific UUIDs.
err_code = softdevice_enable(&ble_enable_params);
APP_ERROR_CHECK(err_code);

Would this also be the preferred way with S132 and SDK 14.2.0? I seem to have the same problem as stated above, yet I don't even find a 'softdevice_enable' in the ble template project...

[Yurii G]

For SDK 14.2.0, "#define NRF_SDH_BLE_VS_UUID_COUNT 3" in sdk_config.h would do.

THAT makes it a lot simpler. Thank you a lot for this first breadcrumb. Would be great if there were an up-to-date tutorial explaining the neccessary steps to create a simple BLE application with service + characteristic, based on the "ble_app_template" from the SDK.

@Phil, totally agreed. Spent a few hours on this trail. I have posted my findings at this question:
