在多个任务中接收BLE事件

你好，

是的，我正在使用带有网格SDK 1.6.1的BLE_MESH示例。

我添加了以下任务并在配置设备后启动它。

目前，这项任务只需启动另一个扫描并检查RSSI实力。我将添加一些代码以稍后识别特定设备。

"public " : "private", ble_address_to_string(&evt->address), (int8_t)evt->rssi); for (p = evt->data; p < evt->data + evt->length; p += ad_len) { ad_len = (*p++) - 1; /* ad_len is length of value only, without type */ ad_type = *p++; /* Device not found so we look for UUID */ if (ad_type == GAP_DATA_TYPE_UUID16_LIST || ad_type == GAP_DATA_TYPE_UUID16_LIST_INC) { size_t idx; for (idx = 0; idx < ad_len; idx += sizeof(uint16_t)) { printf("\tUUID16: %04X\r\n", get_u16(p + idx)); } } /* Look for name and store it to use later, if proper UUID is found */ if (ad_type == GAP_DATA_TYPE_SHORT_LOCAL_NAME || ad_type == GAP_DATA_TYPE_LOCAL_NAME) { dev_name = (const char*)p; dev_name_len = ad_len; printf("\tNAME: %.*s\r\n", dev_name_len, dev_name); } } } static void handle_evt_gap_scan_completed(const ble_evt_gap_scan_completed_t *evt) { printf("SCAN STOPPED\r\n"); start_scan(); } void scanner_main_task(void *pvParameters) { /* Just remove compiler warnings about the unused parameter */ (void)pvParameters; start_scan(); for (;;) { ble_evt_hdr_t *hdr; /* * Wait for a BLE event - this task will block * indefinitely until something is received. */ hdr = ble_get_event(true); if (!hdr) { continue; } switch (hdr->evt_code) { case BLE_EVT_GAP_ADV_REPORT: handle_evt_gap_adv_report((ble_evt_gap_adv_report_t *) hdr); break; case BLE_EVT_GAP_SCAN_COMPLETED: handle_evt_gap_scan_completed((ble_evt_gap_scan_completed_t *) hdr); break; default: printf("Event: %d\r\n", hdr->evt_code); ble_handle_event_default(hdr); break; } /* Free event buffer (it's not needed anymore) */ OS_FREE(hdr); } }

此代码运行一段时间和随机卡。

每次卡住时，位置都不同，所以无法弄清楚原因。

还收到了一些不旨在接收的（与网格函数相关）这样的一些事件.Pz_evt_gap_adv_Completed。

我想知道以下内容：

1.这种方法是否正确？即，我可以在不影响彼此的情况下在多个任务中获得BLE事件吗？

2.如果是，请您查看我的代码和建议是什么问题。

3.如果没有，回到原始问题，如何在网格应用程序中执行单独的扫描？

任何更新？
