2025年蓝牙广播包中自定义厂家数据的设置及获取

大家好，我是讯享网，很高兴认识大家。

硬件: Nordic nrf52840 SoC

软件: Nordic nRF5_SDK_15.2.0_9412b96

1. 蓝牙 perihperal 设备广播自定义数据设定

蓝牙广播相关数据结构定义于 ble_advertising.h

以下为相关数据结构关联示意图

参考样例

 static void advertising_init(void) { uint32_t err_code; ble_advertising_init_t init; memset(&init, 0, sizeof(init)); // define manufacture data of sensor category char data_of_sensor_category[] = 0x20; uint8_array_t array_category; array_category.size = 1; array_category.p_data = data_of_sensor_category; ble_advdata_manuf_data_t device_category; device_category.company_identifier = 0x31; device_category.data = array_category; init.advdata.p_manuf_specific_data = &device_category; init.advdata.name_type = BLE_ADVDATA_FULL_NAME; init.advdata.include_appearance = false; init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE; init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]); init.srdata.uuids_complete.p_uuids = m_adv_uuids; init.config.ble_adv_fast_enabled = true; init.config.ble_adv_fast_interval = APP_ADV_INTERVAL; init.config.ble_adv_fast_timeout = APP_ADV_DURATION; init.evt_handler = on_adv_evt; err_code = ble_advertising_init(&m_advertising, &init); APP_ERROR_CHECK(err_code); ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG); }

2. 蓝牙 Central 设备获取蓝牙广播中的自定义数据

说明: 蓝牙广播原始数据使用 Nordic nRF Connect Android 版本软件获取;

3. adv_report_parse() 数据分析函数

讯享网static uint32_t adv_report_parse(uint8_t type, uint8_array_t * p_advdata, uint8_array_t * p_typedata) { uint32_t index = 0; uint8_t * p_data; p_data = p_advdata->p_data; while (index < p_advdata->size) { uint8_t field_length = p_data[index]; uint8_t field_type = p_data[index + 1]; if (field_type == type) { p_typedata->p_data = &p_data[index + 2]; p_typedata->size = field_length - 1; return NRF_SUCCESS; } index += field_length + 1; } return NRF_ERROR_NOT_FOUND; }
