从geigercounter串行换行读取的C ++ ON NodeMCU随机读取双精度值（是否是换行符？）

Question

从geigercounter串行换行中提取的值由CR换行符指定。但是，该代码似乎随机遗漏了换行符，并将2个cPm值读取为1。例如，将读取2次cPm值2次，结果将cPm 2020值推送到数据库中。

该行为是完全根除行为，无故发生。突然，w的值增加了一倍，然后一切恢复正常，几个小时后我得到正常的20 cPm计数。

直到值突然突然翻倍，再持续几个小时，等等。

我希望有人可以帮助找到解决方案。可以在以下位置找到该代码和更多信息：https://github.com/JanBosNL/esp8266-NetIO-GC-10-GC10-geiger-counter-influxdb
