我在这里关注这个问题，并试图取回我为 Meas/HR 订阅的 DataLogger 的内容。
我正在使用在我的 Windows 10 PC 上运行的传感器模拟器来执行此操作。
我设置 DataLogger 并请求“Meas/HR”，如下所示：
WB_RES::DataEntry entry;
entry.path = "/Meas/HR";
WB_RES::DataLoggerConfig logConfig;
logConfig.dataEntries.dataEntry = {entry};
whiteboard::Result result = asyncPut(WB_RES::LOCAL::MEM_DATALOGGER_CONFIG(), AsyncRequestOptions::Empty, logConfig);
if (result == whiteboard::HTTP_CODE_OK) {
this->asyncPut(WB_RES::LOCAL::MEM_DATALOGGER_STATE(), AsyncRequestOptions::Empty,
WB_RES::DataLoggerStateValues::Type::DATALOGGER_LOGGING);
} else {
DEBUGLOG("asyncPut::datalogger config threw error: %u", result);
}
我按预期返回结果代码 200，然后在 onPutResult(...) 函数中有 1 个条目的数据记录器配置对象。
然后使用 onTimer 函数（仅用于测试目的）我尝试使用以下代码获取日志条目：
this->asyncGet(WB_RES::LOCAL::MEM_LOGBOOK_ENTRIES(), AsyncRequestOptions::Empty);
它运行并进入
onGetResult(wb::RequestId requestId, wb::ResourceId resourceId, wb::Result resultCode,
const wb::Value &result)
回调函数，我得到 HTTP_CODE_OK (200) 的 resultCode 但结果值总是返回为：
result = {mDataTypeId=13313 mSenderDataType=1 '\x1' mReceiverDataType=1 '\x1' ..., mpData = 0x0456f8ac}
为什么它总是返回为 MEM_LOGBOOK_ISFULL_LID = 13313 而不是 MEM_LOGBOOK_ENTRIES_LID = 13312？
是因为我运行的是模拟器模式吗？如果需要填充 DataLogger，我还运行了此命令：
wbcmd.exe --port TCP127.0.0.1:7044 --path Meas/HR --op SUBSCRIBE
但它仍然无法正常工作......
我没有 JIG，所以我需要一些方法来确保它可以在 PC 模拟器上运行，因为我下一步是使用 movesense 传感器记录几天的结果，然后再使用 GATT 将结果发回。我试图避免使用白板和安卓手机软件。
有什么方法可以让我使用模拟器正确地测试它，因为即使尝试以任何其他方式来做这件事也将完全是地狱。我需要手动将数据放入 DataLogger 吗？
帮助！我花了很多时间在这上面，这让我发疯......
谢谢！螺旋
