问题 I'm trying to create an iOS app that will read from an OBDII Bluetooth 4 (LE) device. I purchased a Vgate icar3 bluetooth(4.0) elm327 OBDII. I plug it into my car and find IOS-VLink peripheral that advertises some services. I can then get the characteristics for those services. These are the services I find: <CBService: 0x1780729c0, isPrimary = YES, UUID = Battery> <CBService: 0x178072a80, isPrimary = YES, UUID = 1803> <CBService: 0x178072ac0, isPrimary = YES, UUID = 1802> <CBService:

问题 When an iOS BLE peripheral enters the background state, the advertising packets are not emitted in the regular manner and they are placed in a special “overflow” area which is only detectable by another iOS device explicitly looking for this device. The bluetooth-peripheral Background Execution Mode That said, you should be aware that advertising while your app is in the background operates differently than when your app is in the foreground. In particular, when your app is advertising while

问题 I have an application that acts as a BLE Peripheral and advertises a specific service CBUUIDs, It never connects to the peripherals It is critical for my use case that this app continues advertising even when the app is operating in the background. Though according to Apple’s documentation and several posts from online forums, iOS will severely limit what an app advertise while operating in the background, Is there any way we can advertise the device with name/data in complete background mode

问题 I am attempting to detect battery levels for connected BT devices on macOS. While I can get CBCentralManager to detect SOME nearby devices, all of the devices it detects are name=Null, even though there are numerous devices that should be detected and should have names (e.g., AirPods, magic trackpad, magic keyboard, etc). My BT Manager class is: import Cocoa import CoreBluetooth class BluetoothManager: NSObject, CBCentralManagerDelegate, CBPeripheralDelegate { var centralManager =

问题 CBPeripheralManager.authorizationStatus() and CBPeripheralManagerAuthorizationStatus are deprecated based on apple docs. What is the proper way of checking whether user has granted permission to use bluetooth in background now? CBPeripheralManagerDelegate has peripheralManagerDidUpdateState but that never returns unauthorized regardless of whether user granted the permission or not, instead it only returns poweredOn or poweredOff 回答1: CBCentralManager and CBPeripheralManager inherit from
