使用coded PHY来做Advertising的问题求解

我要使用 ESP32-C3 来做一个 BLE Long Range 广播封包，我使用 multi_adv_demo.c 来修改，程序档案如下，

执行时 log 显示程序正确执行，我也于 Sniffer 上看见了 Long Range 格式的 SCAN RSP 封包。

I (641) MULTI_ADV_DEMO: ESP_GAP_BLE_EXT_ADV_SET_PARAMS_COMPLETE_EVT, status 0

I (641) MULTI_ADV_DEMO: ESP_GAP_BLE_EXT_ADV_DATA_SET_COMPLETE_EVT, status 0

I (671) MULTI_ADV_DEMO: ESP_GAP_BLE_EXT_ADV_START_COMPLETE_EVT, status 0

我现在想要将 Long Range 广播封包改成 ADV 封包，但于

FUNC_SEND_WAIT_SEM(esp_ble_gap_config_ext_adv_data_raw(1, sizeof(legacy_adv_data), &legacy_adv_data[0]), test_sem);

却出现了问题，LOG 如下

I (641) MULTI_ADV_DEMO: ESP_GAP_BLE_EXT_ADV_SET_PARAMS_COMPLETE_EVT, status 0

I (641) MULTI_ADV_DEMO: ESP_GAP_BLE_EXT_ADV_DATA_SET_COMPLETE_EVT, status 0

请问我该如何修改呢？
