iOS CoreBluetooth CBPeripheral didReceiveReadRequest

Question

我有两个项目。一个起中心作用，另一个起外围作用。中央已经连接到外围，然后中央调用方法readValueForCharacteristic。不是立即，而是在大约5-10秒之后，外设调用委托方法- (void)peripheralManager:(CBPeripheralManager *)peripheral didReceiveReadRequest:(CBATTRequest *)request.为什么会有延迟？怎样才能消除延误呢？有什么想法吗？我已经试了将近一个星期了。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;
        }
    }];
}

围周

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

Answer 1

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

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