英文:
react-native-ble-plx disconnects from BLE device whenever I use navigation.navigate()
问题
我正在使用React Native上下文将数据从一个简单的react-native-ble-plx脚本传递到我的应用程序中的不同屏幕。我在这些屏幕上使用react-native-navigation。每当我调用navigation.navigate()时，我成功地导航到另一个屏幕，但即使我导航回原始屏幕，蓝牙通信也不再有效。如何在我的BLE上下文中继续将数据发送到应用程序的不同屏幕，而不断开连接？
英文:
I am using React Native context to pass data from a simple react-native-ble-plx script to different screens in my app. I'm using react-native-navigation for these screens. Whenever I call navigation.navigate(), I successfully navigate to another screen, but I no longer have bluetooth communication, even if I navigate back to the original screen. How do I keep sending data from my BLE context to the different screens in my app, without disconnecting?

我相信这是因为您在页面上处理/监控连接，而不是通过服务来处理。将BLE功能与UI分开应该可以解决这个问题。请查看以下链接获取更多信息：
英文:
I believe that this is happening because you are handling/monitoring the connection on the page instead of doing it via a service. Separating BLE functionality from the UI should fix this issue. Have a look at the links below for more information:-

这不是真正的一个“解决方案”，但我通过从我的项目中移除React Navigation，并像这样手动处理屏幕来解决了这个问题：
<View>
{showScreen1 && <View></View>}
{showScreen2 && <View></View>}
</View>
英文:
This is not really a "solution" but I solved this problem by removing React Navigation from my project, and just handling the screens manually like this:
<View>
{showScreen1 && <View></View>}
{showScreen2 && <View></View>}
</View>
