Not sure what do you mean by Background mode.不知道你说的后台模式是什么意思。 Do you mean when the app is minimized or do you mean in background thread?您是说应用程序最小化时还是在后台线程中？
As far as being continuously connected with the BLE device is concerned then yes it is possible!就与 BLE 设备的持续连接而言，是的，这是可能的！ Provided your BLE device is continuously powered on and available.前提是您的 BLE 设备持续通电且可用。
You'd have to search for particular service and then its characteristics using Core Bluetooth.您必须使用 Core Bluetooth 搜索特定服务，然后搜索其特征。
Mind you this could be a battery draining operation.请注意，这可能是电池耗尽操作。
Suggestion would be to connect read what you want to read and disconnect.建议是连接阅读您想要阅读的内容并断开连接。
