nrf_error_svc_handler_missing in sd_ble_cfg_set

[ali_dehghan_nayeri]

hi all. 

I am trying to change number of data packets in one time interval.

I don't know the senario to change it.

For first step I wrote this code to change the quee size.

I got this error.

ble_gatts_conn_cfg_t cfg_t;
cfg_t.hvn_tx_queue_size = 5;

ble_conn_cfg_t cfg={0};
cfg.conn_cfg_tag = 1;
cfg.params.gatts_conn_cfg = cfg_t;

ble_cfg_t final_cfg={0};
final_cfg.conn_cfg = cfg;
final_cfg.conn_cfg.conn_cfg_tag = 1;
final_cfg.conn_cfg.params.gatts_conn_cfg.hvn_tx_queue_size=5;
uint32_t app_ram_base = 0x20002280;
error_cfg = sd_ble_cfg_set(BLE_CONN_CFG_GATTS ,&final_cfg,app_ram_base);

please help for the senario steps to change the number of packets and the error.

I use sdk 17.0.2 and s132 v7.2.0

thanks

I am trying to change number of data packets in one time interval.

 When you set hvn_tx_queue_size, you set the minimum guaranteed number of Handle Value Notifications that can be queued for transmission. Try instead to increase
NRF_SDH_BLE_GAP_EVENT_LENGTH in sdk_config.h

so how can I solve this

<error> app: ERROR 1 [NRF_ERROR_SVC_HANDLER_MISSING]?

I call sd_ble_cfg_set after enabling the soft device.

what is the problem?

thanks.

 Did you debug, and check where in the code APP_ERROR_CHECK() is triggering?

I suspect this is actually coming from the uart_event_handle():

        case APP_UART_COMMUNICATION_ERROR:
            APP_ERROR_HANDLER(p_event->data.error_communication);
            break;

and that the error is really NRF_UARTE_ERROR_OVERRUN_MASK. Please check this by taking a look at the value of app_uart_evt_t::error_communication when the error occurs. As indicated here, the value is 1 when the UART is overrun. So try placing a breakpoint at
"APP_ERROR_HANDLER(p_event->data.error_communication);".

I finally got ridde out of error by writing same as nrf_sdh_ble_default_cfg_set() function.

memset(&ble_cfg, 0, sizeof (ble_cfg));
ble_cfg.conn_cfg.conn_cfg_tag = 1;
ble_cfg.conn_cfg.params.gatts_conn_cfg.hvn_tx_queue_size = 4;
ret_code = sd_ble_cfg_set(BLE_CONN_CFG_GATTS, &ble_cfg, *p_ram_start);
APP_ERROR_CHECK(ret_code);

but when I print count in BLE_GATTS_EVT_HVN_TX_COMPLETE, it prints always 1 and I get the error NRF_ERROR_RESOURCES again.

I think the increasing queue size hasn't been affected.

I couldn't find a function like ble_sdh_cfg_get() to sure about the queue size.

 You could get several BLE_GATTS_EVT_HVN_TX_COMPLETE with count=1 in the same connection event.

You should be able to queue minimum 4 notifications before getting NRF_ERROR_RESOURCES
