When calling sd_ble_uuid_encode()
I get NRF_ERROR_INVALID_PARAM in one project while in another I get NRF_SUCCESS with the same params on same SoftDevice(S110 8.0.0) on same DevKit(nRF51422):
The first screen is from SDK 10.0.0, example ble_app_uart and it's fine. The second is ble_app_hrs which is modified so that it advertises BLE_UUID_NUS_SERVICE in scan response (I am trying to reuse bonding from ble_app_uart and just replace heart service with uart service from ble_app_uart). The problem now is that device does not advertise because of this error.
Relevant code:
static ble_uuid_t m_adv_uuids[] = {{BLE_UUID_NUS_SERVICE, BLE_UUID_TYPE_VENDOR_BEGIN}}; // {{0x0001, 0x02}}
static void advertising_init(void)
{
uint32_t err_code;
ble_advdata_t advdata;
ble_advdata_t scanrsp;
// Build advertising data struct to pass into @ref ble_advertising_init.
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = false;
advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;
memset(&scanrsp, 0, sizeof(scanrsp));
scanrsp.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
scanrsp.uuids_complete.p_uuids = m_adv_uuids;
ble_adv_modes_config_t options = {0};
options.ble_adv_fast_enabled = BLE_ADV_FAST_ENABLED;
options.ble_adv_fast_interval = APP_ADV_INTERVAL;
options.ble_adv_fast_timeout = APP_ADV_TIMEOUT_IN_SECONDS;
err_code = ble_advertising_init(&advdata, &scanrsp, &options, on_adv_evt, NULL);
APP_ERROR_CHECK(err_code); // err_code = NRF_ERROR_INVALID_PARAM; from sd_ble_uuid_encode()
}
I compared main.c from both projects (ble_app_uart and ble_app_hrs) to make sure I'm not missing some configuration but I am not. What is wrong here?
