【问题描述】:
BLE 在 7 Plus (iOS 14.4.2) 和 6 (iOS 12) 上运行良好。但是在 XR (14.4.2) 和 11 连接在centralManager.connect(peripheral, options: nil) 之后卡住(无限连接)
外围设备处于连接模式,因为其他智能手机无法检测到它。 一开始以为是外围设备本身的射频模块(NRF52)有问题,但是调试板也出现了问题。 重新启动智能手机没有帮助。 有趣的是,该应用程序在配备 M1 芯片的 MacBook 上运行良好
部分代码:
// Peripheral model
init(withPeripheral peripheral: CBPeripheral, advertisementData advertisementDictionary: [String : Any], andRSSI currentRSSI: NSNumber, using manager: CBCentralManager) {
centralManager = manager
basePeripheral = peripheral
RSSI = currentRSSI
super.init()
advertisedName = parseAdvertisementData(advertisementDictionary)
basePeripheral.delegate = self
}
public func connect() {
centralManager.delegate = self
centralManager.connect(basePeripheral, options: nil)
print("Connecting to \(advertisedName ?? "device")...")
// logs stops here
}
public func disconnect() {
centralManager.cancelPeripheralConnection(basePeripheral)
print("Cancelling connection with \(advertisedName ?? "device")...")
// triggers on VC dismiss
}
func centralManagerDidUpdateState(_ central: CBCentralManager) {
if central.state != .poweredOn {
print("Central Manager stated changed to \(central.state)")
}
}
func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {
if peripheral == basePeripheral {
print("Connected to \(advertisedName ?? "device")")
delegate?.peripheralDidConnect()
discoverPrimaryServices()
}
}
func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: Error?) {
if peripheral == basePeripheral {
print("Disconnected from \(advertisedName ?? "device")")
delegate?.peripheralDidDisconnect()
}
}
