我正在尝试从具有CoreBluetooth的iPad连接到MacBook Pro。
这是我的CBCentralManagerDelegate
代表团:
extension MasterViewController: CBCentralManagerDelegate {
func centralManagerDidUpdateState(_ central: CBCentralManager) {
if central.state == .poweredOn {
print("Scanning for peripherals")
central.scanForPeripherals(withServices: nil, options: nil)
Timer.scheduledTimer(timeInterval: 3, target: self, selector: #selector(self.stopScan), userInfo: nil, repeats: true)
}
}
func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
print("Did discover peripheral", peripheral)
central.connect(peripheral, options: nil)
}
func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {
print("Did connect to ", peripheral)
peripheral.delegate = self
self.remotePeripheral.append(peripheral)
}
func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: Error?) {}
}
但是当我扫描时,我在日志中收到此错误:
<Error>: [CoreBluetooth] API MISUSE: Cancelling connection for unused peripheral
为什么会这样?
最佳答案
不知道为什么这样做有效,但是我发现如果我将外围设备委托分配给self,并在连接到外围设备之前将外围设备添加到阵列中,那么它会工作。
func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
print("Did discover peripheral", peripheral)
peripheral.delegate = self
self.remotePeripheral.append(peripheral)
central.connect(peripheral, options: nil)
}
关于ios - 由于API滥用,CoreBluetooth正在与未使用的外围设备断开连接,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/40113545/
