iOS CoreBluetooth CBP外围设备didReceiveReadRequest

Question

我有两个项目。 一个充当中心，另一个充当外围设备。 中央已连接到外围设备，然后中央调用方法readValueForCharacteristic 。 不是立即，而是在大约5-10秒后，外围设备调用了委托方法- (void)peripheralManager:(CBPeripheralManager *)peripheral didReceiveReadRequest:(CBATTRequest *)request 。 为什么会有延迟？ 如何消除延迟？ 有什么想法吗？ 我已经尝试了将近一个星期。 感谢每一个帮助，谢谢

中央

- (void)sendBtnClick:(id)sender
{
    USCPeerBtn *btn = (USCPeerBtn *)sender;
    CBPeripheral *peripheral = btn.connectedPeripheral;
    if (!peripheral) {
        return;
    }

    [self.charachterMDict enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) {

        if (key == peripheral) {
            [(CBPeripheral *)key readValueForCharacteristic:(CBCharacteristic *)obj]; // read
            *stop = YES;
        }
    }];
}

// CBPeripheralManagerDelegate
- (void)peripheralManager:(CBPeripheralManager *)peripheral  didReceiveReadRequest:(CBATTRequest *)request
{
    NSLog(@"didReceiveReadRequest");
}

Answer 1

调用respondToRequest:在方法- (void)peripheralManager:(CBPeripheralManager *)peripheral didReceiveReadRequest:(CBATTRequest *)request

// CBPeripheralManagerDelegate
- (void)peripheralManager:(CBPeripheralManager *)peripheral     didReceiveReadRequest:(CBATTRequest *)request
{
    [peripheral respondToRequest:request withResult:CBATTErrorSuccess];
    NSLog(@"didReceiveReadRequest");
}  

@ Paulw11，谢谢
